►The "TT" is a new type of competition created within the Class C rules.
A "Miniature TT" is a "TT" event on a course less than one mile in length. From the 1933 Rules For Competition: "The term Tourist Trophy (or "TT") is derived from the famous Tourist Trophy races held each year in the Isle of Man. It represents, on a small scale, a road race, and consequently should embrace, to the closest possible extent, all the conditions that would be met in driving on the open road. The course should be irregular insofar as possible, so that both right and left hand turns have to be negotiated. It is advisable to include, if possible, a hill that will necessitate gear changing so that the entire motorcycle is made to perform its regular road functions."

►All divisions use black numbers on white number plates.
Note: Rider numbers are not assigned until late 1942.
District letters are not introduced until 1947.

►Frenchy Castonaguay sets a record fast qualifying time at the August 17, 1941 Springfield Mile, but the time is uncertain. The September 1941 The Motorcyclist lists Frenchy's time as 42.64, while other periodicals state 43.64. The issue comes to light when Jerry Callen sets a 42.900 second lap in 1950, but it is unclear whether that time is a new record or not. The editor of The Motorcyclist asks in Septmber 1950: "There must be an error somewhere. Can anyone set us straight?"

The Motorcyclist, September 1950

►The AMA issues "Permanent National Numbers" for the first time to the top riders in the nation. Numbers 1-14, 16-17, 21-27, 29, 32-33, 35, 38, 55, and 72 are issued. In the October 1941 issue of The Motorcyclist, competition director E.C. Smith writes: "Effective at once, expert riders in dirt track racing have been assigned a permanent riding number. We feel that this will add something to the show as spectators will get to know the riders better and most of all, the riders won't have to have different numbers made up for each race meet. They can now get their numbers and carry them throughout the year. They can have on on their trailer, their mechanic's coveralls, etc. We ask that they adopt a uniform number at least ten inches, black on white background and also have a number for their right rear wheel. If they wish they can have three numbers, one for the front and both sides of the rear wheel or on the front and right of rear wheel."

►Frenchie Castonaguay is the brother of 1935 & 1938 Class C National Champion Woodsie Castonaguay, marking the first (and, as of 2022, the only time) that brothers have each won the National title.

►Harley-Davidson introduces the race-only "WR", 750cc V-twin side-valve hand-shift racing model, for Class C competition. The WR replaces the WLDR as the primary race weapon.

►AMA Competition Committee meets in Daytona Beach, Florida on February 19-20, 1947.
►To address scoring issues with over 1,600 professional competitors, a new "permanent number" system is created.

►Three plates, at least 10" x 10" square, should be used. Numbers to be at least 8" tall.
►"Straight numbers" (what are now known as "National Numbers") are assigned to Experts, National Champions, and a few Amateurs in each class (Racing, Hill Climbing, and Tourist Trophy).
►The "letter system" divides the country up into alphabetical sections.
►Wheels: Contestents must use the standard wheels that come as a specificed part of the Class C motorcycle.
►New wording: "Class C equipment shall have no alteration in bore, stroke, frame, forks, or type of motor. Alteration means brazing, cutting, or fabricating and thus the rider can use different types of forks, etc, provided they are not altered to fit."

►Class C Hillclimb: New program will be four events: 45ci Novice, 80ci Novice, 45ci Expert, and 80ci Expert.

►Class A Hillclimb: The winner of the Class B event at the National Championship automatically advances to Class A the following year.

►Any rider under 21 years of age will not be accepted unless the written consent of parents or guardians accompanies the application.

►Any rider who plans to compete in dirt track racing, hill climbing, TT racing, road racing, speedway racing, or night speedway racing on and after April 1, 1947, must have his competition license.

►The applicant must be a member of the AMA and the license fee of $1.00 must accomplany the application.

►Age Limit: A 15-year age limit on motorcycle used in competition [will] start in 1948. (So no motorcycle built prior to 1933 is eligible to compete in 1948).

►Prize Money is standardized as follows:

TT Racing

►One-Star = $150 purse
►Two-Star = $300 purse
►Three-Star = $400 purse
►Four-Star = $500 purse
►Five-Star = $600 purse
►Each additional "star" is another $100 in the purse.

Dirt Track Racing (half mile)

►One-Star = $300 purse
►Two-Star = $600 purse
►Three-Star = $900 purse
►Four-Star = $1,200 purse
►Five-Star = $1,500 purse
►Each additional "star" is another $300 in the purse.

Dirt Track Racing (mile)

►One-Star = $1,000 purse
►Two-Star = $1,500 purse
►Three-Star = $2,000 purse
►Four-Star = $2,500 purse
►Five-Star = $3,000 purse
►Each additional "star" is another $500 in the purse.

Purse Breakdown

►All events above one-star: 45% for Expert, 35% for Amateur, 20% for Novice.
►All one-star events: 60% Amateur, 40% Novice. Experts will not compete at One-Star events.

General Rules

►The "hold position" flag is added. It is red and white diagonal. It is used in the event of an accident.

►AMA National Championship entry lists prior to 1947 do not show any district letters in use. Interestingly, the Number 1 followed by a district letter is assigned to several riders. This practice continues for several years.

►The American Motorcyclist magazine's May 1947 issue includes a two-page explanation of the new "permanent" numbering system. What we now know as "National Numbers" are listed as "Straight numbers". The "district letter" is merely referred to as a "letter", stating the country is divided up into alphabetical sections and the riders residing in the particular section will carry a certain letter on their number plates". It also recommends that all number plates be at least 10" square. (American Motorcyclist, May 1947).

►JAP wins its last dirt track National (Cordy Milne at Los Angeles, CA short track event).

"As of January 1 (1947), every AMA competition rider in dirt track racing, hill climb, TT racing, night speedway racing, road racing, and speedway racing will be covered by surgical and hospitalization insurance, and the cost for this insurance will be $1.00 per year!! Yes, that is right, just one dollar per year! Full details of this program will soon appear in all motorcycle publications."
(AM Magazine, Volume #1, Issue #1, Page 4, January 1947)

(Article III — Section 5-D).

Number Plates
►No single item of equipment has caused so much confusion and possible error in computing results in motorcycle competition of all kinds as the persistence of some contestants in the use of poorly designed and illegible number plates. In order to preclude to the greatest extent possible, this error recurring for the 1948 season, only such number plates as are herein outlined will be permitted to start in any race meet.

►All number plates used by all contestants must be of uniform size, shape, and thickness of material as follows:

►10" high 12" wide not less than 0.045" thick. The four corners must be cut off at a radius of 2-1/4".

["Chet Dykgraaf: The First Number One" by Darya Mallard in Vintage Mounts, July 1987].

1949

Qualifying for the 1949 Langhorne 100 is held on Saturday September 3.
The race is held on Sunday September 4, 1949.

►1,688 AMA-sanctioned events were held in 1948. 345 race meets, 195 short track races, 38 Class A hill climbs, 94 Class C hill climbs, 331 TT races, 224 reliability trials, 69 endurance runs, 130 turkey runs, 204 field meets, 10 polo games, and 68 miscelleneous events (including hare and hound chases, treasure hunts, and secret destination runs).

►Spectator attendance reached the record total of 6,573,000

►Program Committee creates a standard program for the National Championship events.
Two Amateur heats and one Amateur final,
Two Expert heats one Expert final, and a series of consolation events for remainder of the Experts entered.

►Prize money at National Championships will be approportioned 80% to Experts, 20% to Amateurs.

►The Committee revoked the limitation of one-star race meets to Novices and Amateurs.
The original idea was to encourage more Novice and Amateur race meets.
It didn't do the job. It also created a hardship in sections where there were a few Experts.

Short Track Classified
►Short track or night speedway race meets were classified:

►CLASS A — One-star: $750; Two-star: $1,000, Three-star: $1,250, Four-star: $1,500
►CLASS C — One-star: $450; Two-star: $600, Three-star: $750, Four-star: $900
►Number of starters (in Class C short track) will be limited to six, and the number of laps limited to 10.
►In districts where there is an obvious lack of classified riders, the chairman of the Competition Committee has been empowered to grant sanctions for the progressive type of program. The applying club must make such request on the sanction application, and the approval must appear on the sanction and on the entry blank.
►In competitive events, the practice of riding in a prone position, with feel extended over the rear mudguard and wheel, shall be prohibited. Penalty: disqualification.
►Motorcycle equipment used in time trials must be used in heats and final event.
There has been a tendency to use small tanks in time trials and then change for the races.
This is not fair to all contestences and is therefore eliminated.
►A committee composed of H.M. Syvertson, Earle Robbins, and John Hostetter was appointed to investigate the possibility of a cut out control for track racing.

No Major Rule Changes

►There were no major rule changes in the general rules.
The Committee felt that the rules were definitely constituted to permit the greatest possible number of riders to compete, and that problems of enforcement and safety shold be given careful study.

►The AMA will send a 1949 rulebook to every licensed rider.

►The Technical Commitee made the following recommendations, which were approved by the Commitee:

►Any release relative to any technical equipment must be cleared through the technical committee first.

►All motorcycles must be fitted with a guard completely enclosing the front chain, etc.

►Add to approved tires: Rally and Kelley Springfield.

"The analysis of the mutual contributions and the accident experience shows that the increase in the cost of the license fee in 1949 was the saving factor of the program. Without that, the fund would have operated at a loss. The accumulated surplus permits an added benefit for the year 1950, and rather than reduce the contributions by one or two per cent, the limit of liability has been increased from $300 to $400."
(AM Magazine, Volume #4, Issue #3, Page 41, March 1950)
[Comment: the article indicates 3,537 licenses were sold, for revenue of $17,685. This is $5 per license. The program was unveiled in 1947 at $1 per license.]

1950

►Amateur Jerry Callen sets the fastest qualifying lap at the Springfield Mile on August 18, 1950 at 42.900. Paul Goldsmith is the fastest Expert at 43.09. It is unclear whether this sets a new track record or not, as there is confusion as to what Frenchy Castonaguay's fast time really was. The September 1941 The Motorcyclist lists Frenchy's time as 42.64, while other periodicals state 43.64. The editor of The Motorcyclist asks in Septmber 1950: "There must be an error somewhere. Can anyone set us straight?"

The Motorcyclist, September 1950

The manufacturer of the motorcycle must have sold or available for sale to the general public in the U.S.A. 25 or more of the motorcycle of the model in question, before it can be entered in any Class C Competition event.
(1950 AMA Rules For Competition, Article III, Section 4(b), Page 7).

1950 is the first time that the formal approval process for Class C equipment is in the rule book, including a minimum quantity for sale.

►A DOHC version of the 1949 Norton Manx appears in early 1950, without going through the formal approval process.
Norton owners argue that the DOHC Manx engine is still "basically" the same as the the SOHC International engine.

►The AMA rulebook adds claiming for the first time.
(a) All sanctioned Class C dirt track race meets, speedway races, road races, T.T. races, short track races and hill climbs shall be considered claiming events and the claiming price shall be set at $1,000.00.
(1950 AMA Rules for Competeition, Article III, Section 4, Page 7).

►Harley-Davidson first offers a steel 10"x12" number plate with beaded edges in its 1950 catalog.

1951

►Triumph wins its first dirt track National (Jimmy Phillips at Peoria, IL TT event).


► The AMA Rulebook, Article I, Section 1, removes the statement that "Membership (in the AMA) is limited to white persons only."

1952

►The AMA approves the Harley-Davidson "KR", twin-cylinder, side-valve, foot-shift racing model, for Class C competition.

►1952 AMA Rules for Competition, Article II, Section 1 (Page 6) and Article III, Secton 1 (Page 7) both refer to Class D riders and Class D equipment. It does not state anything else.
►The January 1997 edition of American Motorcyclist mentions that the AMA experimented with "Class D" racing for Novice racers on small-displacement street machines.
References to Class D do not appear in the 1953 AMA Rules for Competition.

►BSA wins its first AMA dirt track National (Al Gunter at Shreveport, LA half mile event).


►The 15-mile Mile National at Milwaukee, WI on August 24, 1952 runs 19 laps. After 10 laps, Billy Huber crashed. The red & white "hold position" flag was displayed. It took 4 "hold position" laps to clear an uninjured Huber and his machine from the track. Once clear, they continued the 15-lap race from there. Hence the 15-mile National that ran for 19 laps.

1953

►Novice division riders begin using green number plates with white numbers and district letters (previously had used yellow number plates with black numbers and district letters since 1948).

►Indian wins its last AMA dirt track National (Ernie Beckman at Williams Grove, PA half mile event) until 2017.


►Santa Fe Speedway opens in Willow Springs, IL on May 31, 1953, with a sprint car race. It would run motorcycle races until 1988.

►Indian Motorcycle Company goes out of business in 1953.

1954

Meets January 6-8, 1954 in Columbus, Ohio.

►AMA creates the Grand National Championship series to award the Class C National Championship to the rider who earns the most points in a series of events involving four racing disciplines: half mile, mile, "TT", and road racing. This "series" replaces the one-race championship system that dates back to 1935.

►41 racers earn Grand National points, and 10 racers score wins, in eighteen events in 1954.
►Points are awarded in the final only: 9-7-5-3-2-1.

1955

►41 racers earn Grand National points, and 7 score wins, in seventeen events in 1955.
►9-7-5-3-2-1 (same as 1954).

►Andres led after round 1.
►Brashear & Andres tied after round 2.
►Brashear led after round 3.
►Andres led after rounds 4-7.
►Brashear led after round 8.
►Brashear & Andres tied after round 9.
►Brashear led after rounds 10-13.
►Andres led after rounds 14-17.
►Brashear only scored points in 6 of the 17 rounds, and none after winning round 12.

►Ohio Amateur George Roeder (#95F) convinces Ohio Expert Frank Gayoski (#60) to claim the winning KR at the Richmond, VA HM National on May 29, 1955. George had been running a WR unsuccessfully against the more modern KR's. George's tuner had suggested that claiming a National-winning KR would be better than buying a brand new motorcycle. Everett Brashear wins the race and then loses his KR, which had a very special set of Tom Sifton cams in it. Roeder, unaware of the special cams, soon blows the engine up. Brashear immediately implements a new policy whereby he quickly remove the cams from the engine anytime that he wins a race.

Steel Shoes

►Flat steel shoes are barred as these caused several major accidents.
Riders must now use a steel shoe that curves over the toe of the boot or shoe.

Sportsman Class

►The Sportsman class is created for the benefit of the average road rider to compete in most every type of competition. A committee has been formed to formulate the rules for this new class of competition.

Frames

►Spring frames can be converted to rigid frames by the use of struts.

Exhaust Systems:

►There must not be less than six inches of exhaust pipe running parallel to the ground or with the rear end elevated previous to the point of discharge, but not to extend beyond the rear edge of the rear rim.

►In all National Championship dirt track race meets, the elimination heats shall be 5 miles on half mile tracks and 10 miles on mile tracks.

►On all Speedway events on tracks of one mile or over, and when Novice events are scheduled, the Novice must have at least 20 points before they can compete.

►When the Central Office has a spot check on motor measurement, instead of measuring the three place winners, three names from the 12 qualifying riders be drawn from a hat and those selected, have their motors measured.

►In the event of a rain and 50% of the program has been completed with not any refund to spectators, the balance of the purse will be paid to qualified contestants.

►Article VI: Change to read — where an entry fee is charged, the maximum shall be $2.00.

►Article VII — Section 21 - Add — All closed circuit courses must be run counter clockwise.

►40 points to advance from Novice to Amateur. (Had been 25 points since 1949)
►60 points to advance from Amateur to Expert. (Had been 40 points since 1949)
(1955 AMA Rules For Competition, Article II, Section 5, Page 6).

The 1955 Competition Committee increased these - retroactive to 1954 - as they felt that Novice and Amateur racers are not gaining enough experience.
(January 1956 issue of American Motorcycling)

►No rider under 21 years of age may compete without written consent of parents or legal guardian.
Minimum age for competition license is 18 years old.
(1955 AMA Rules For Competition, Article VII, Section 8, Pages 15-16).
(18 year age limit was added by the 1955 Competition Committee)

►The Triumph T-100R 500cc overhead valve twin is approved by the Technical Committee


►The 1955 BSA Gold Star 500cc overhead valve single is approved by the Technical Committee with the understanding that the bore and stroke be 85mm by 88mm and limited to 8:1 compression.


►The 1955 Norton 30 Manx, a 500cc DOHC race-only single-cylinder, is rejected by the AMA Technical Committee. See 1956 for explanation.

►Gasoline shall not exceed 100 octane rating. Additives of any type over and above that contained in regular commercial gasoline of 100 octane rating is prohibitive [sic].
(1955 AMA Rules For Competition, Article III, Section 5(g), Page 10).
(Had been 85 octane since 1948).

►At the July 4, 1955 Dodge City, Kansas 75-mile Road Race National and the October 9, 1955 Torrey Pines, California 125-mile Road Race National, riders use their "dirt track" numbers (with district letters).
Brad Andres wins both events wearing #11R.

1956

►19 racers earn Grand National points, four four score wins, in seven events in 1956.
►9-7-5-3-2-1 (same since 1954).

►The Daytona 200 does not award championship points.
►The Springfield Mile is rained out on Sunday August 19, and runs instead on Monday August 20.
The AMA decides not to award championship points for the rain date.

►The Class C 45 Road Race and CLass C 80 Road Race classes are replaced by Formula C Road Race class.
Up to 45ci (750cc) side valve or 30.50ci (500cc) overhead valve engines.
(1956 AMA rulebook; page # TBD)

►Compression Ratios and Displacements. A lengthy discussion concerning compression ratios and displacements took place. Rod Coates and John Esler opined that compression ratios should be increased. Bill Harley presented performance data and race results which indicated that the current system is balanced.

►A motion (Aub LeBard MM / Earl Flanders SM) to delete maximum compression of 8:1 from the rulebook, allow overhead valve engines an increase from 30.50ci (500cc) to 40.0ci (655cc), and limit any overhead valve engine above 30.50ci to 8.5:1 compression, was defeated 16 to 11.

►A motion (Aub Lebard MM / John Esler SM) to allow 30.50ci engines be allowed unlimited compression was defeated 16 to 11.

►A motion (Aub LeBard MM / Earl Flanders SM) to place 30.50ci engines in a separate class was defeated 17 to 9.

►A motion (Horace Fritz MM / John Ciccarelli SM) to raise allowable compression on 30.50ci engines from 8:1 to 9.5:1 was defeated 14 to 13.
Note: Committee member Gerald Givens, a dealer of British engines, resigned his appointment and left the meetings earlier in the day. Had he remained, the 9.5:1 ratio may have passed.

►A motion (Horace Fritz MM / John Esler SM) to raise allowable compression on 30.50ci engines from 8:1 to 9:1 was passed 15 to 12.

►Aub LeBard requested an explanation as to why the 1955-56 model 30 Manx-Norton was not approved by the Technical Committee for Class C competition. Rod Coates of the Technical Commission provided a lengthy response.

Per Rod Coates of TriCor, and a member of the AMA Technical Committee: The new model has undergone considerable changes from the original 1949 model, including new bore and stroke (86mm x 85.62mm = 497cc). Also, the cylinder barrel and cylinder head castings differ greatly from the early Manx or International parts.
The Committee felt that the new Manx model could not be approved as there had never been a standard production model regularly sold for everyday use which utulized these basic parts and new bore/stroke".

A motion to accept the response was passed by unanimous vote.

►A motion (Walter Davidson MM / Bill Harley SM) made to reject the Norton Manx as submitted for approval was passed 20 to 5.

►A motion (Bill Harley MM / Horace Fritz SM) made to deny a 50-mile road race National Championship sanction to Windber, Pennsylvania was passed 16 to 10.

►A motion (Aub LeBard MM/ Walter Davidson SM) to limit all National Championship events to one each of each type of motorcycle competition was passed 14 to 11.

►The 10-mile HM National at Columbus, Ohio was accepted with a $3,750 purse.
A 5-mile HM National at Richmond, Virginia, an 8-mile HM National at Schererville, Indiana, a 6-mile HM National at Sturgis, South Dakota, a 7-mile HM National at Minneapolis, Minnesota, a 5 or 6-mile HM National at Kansas City, Kansas, a 9-mile HM National at Milwaukee, Wisconsin, and an "any distance" HM National at Heidelberg, Pennsylvania were rejected.
►A 20-mile M National at Bay Meadows, California was accepted with a $6,500 purse.
►A 100-mile Road Race National at Laconia New Hampshire was accepted, with provisions, with a $5,000 purse.

►Chris Draayer crashes at the August 25, 1967 Sedalia non-National mile. He was close behind definding champion Bart Markel when Markel's engine let go. Draayer avoided Markel, but hit an unprotected fence in the process. Draayer lost his right arm in the crash, and never raced again. Draayer was fifth in Grand National points at the time, and had just missed winning the Santa Fe ST National the week before. Markel was so distraught by the incident that he didn't race again for the rest of the year.

(Midwest Motorcyclist Action, June 24, 1968 issue).

►The AMA issues a competition bulletin on August 9, 1968 to all referees. It states: "A board appointed by AMA President, William Bagnall, under the provisions of Section C1, Chapter 1X of the AMA Rules, has met and upheld the decision of an AMA Referee, prohibiting the use of a compression release. This matter is being called to your attention so there will be no doubt in your mind as to what your position as an AMA Referee should be if a contestant tries to enter a race with a machine equipped with a compression release."
(AMA Competition Bulletin, August 9, 1968).

► Prior to a RAM event at Queen City Speedway in Charlotte, NC on August 17, 1968, the RAM Competition Committee met to discuss the compresion release issue. "After hearing arguments from both two-stroke and four-stroke advocates, they decided to allow the compression releases on the following grounds:
1) Safety is improved by the use of a compression release. (With more comparabe engine braking there is less chance of the 2-strokes running over the 4-strokes as they decelerate through the turns).
2) The compression release provides the 2-stroke enging NO more engine braking power than that available to the 4-stroke engine."
(Cycle Sport Magazine, October 1968 issue).

Editorial comments on the 750cc rule change:

►Comment 1: It appears that since there were so few road races at the time that the Competition Congress focused solely on dirt track rules, and left the road race engines with the antiquated 500cc limit for overhead valve and two-stroke engines.

►Comment 2: The change of heart concerning the 350cc plan seems to stem from the Yamaha YR2 350cc two-stroke twin, which was approved in 1968. The "little" 350cc two-stroke twins were proving to be very competent at road races - finishing 2nd and 3rd at the 1968 Daytona 200 - and had already scored some decent Mile dirt track finishes in 1968. The concern was that if 350cc two-stroke twins are proving to be competitive against 500cc/750cc four-stroke engines, then 350cc four-strokes wouldn't have a chance against 350cc two-strokes.

►Comment 3: Triumph recommended raising the 350cc limit to 650cc, since Triumph and BSA already had competent 650cc TT engines, and they knew that Harley-Davidson did not produce a 650cc motorcycle. Reportedly, Walter Davidson consulted quickly with Bart Markel, who confirmed that there was no feasible way to convert the 883cc XLR overhead valve engine down to a 650cc displacement. Hence, Davidson counter-proposed to amend the 650cc proposal to 750cc, but also to delay the implementation for one full year - until 1970 - to give Harley-Davidson time to develop a new 750cc overhead valve engine. The Congress accepted the 750cc proposal, but not the one year delay.

►Comment 4: Starting in 1969, new motorcycles needed to have 200 complete motorcycles built and inspected to obtain AMA approval.
BSA and Triumph get their 750cc OHV triples (the Rocket III and Trident, respectively), approved on March 10, 1969.
Harley-Davidson's Iron XR 750cc OHV twin is approved on February 27, 1970.
Triumph is next with their bored-out 120\RT 750cc OHV twin on June 26, 1970.
BSA's A70L stroked-out 750cc OHV twin is approved on September 13, 1971.
Yamaha's GXS-1 bored-out 750cc OHV twin is approved on November 2, 1971.

►Bultaco scores its first dirt track National (Ronnie Rall at Houston, TX short track event).


►Ossa scores its first dirt track National win (Dick Mann at Hinsdale, IL short track event).


►Mert Lawwill wins the final AMA National for the KR engine at the season finale at Ascot Park.


►The Mikuni VM round-slide carburetor first appears on the Yamaha TD2 250cc two-stroke twin

►Harley-Davidson begins design efforts on a 750cc OHV engine to replace the KR. Originally billed as a '750cc Sportster', it eventually becomes the 'Iron XR'. Matt Kroll is the Lead Engineer, working under the direction of Dick O'Brien, with Pete Zylstra working as draftsman on the project.

License Changes:

►No USA rider may be issued a license other than a Novice license on a first-time basis, or advanced in classes without unanimous endorsement of two Competition Congress members and the District Referee. All must be familiar with the rider and why a rider should be allowed to pass up the Novice or Amateur class.

►Riders from foreign countries will be granted on Expert licenses. Rider applying for license shall have the equivalent rating in his own association.

►Mert Lawwill and Mark Brelsford miss the first 750cc dirt track national of the season (April 19, 1970, Palmetto, Georgia HM) as their bikes were not shipped from the Friday night Ascot HM in time.

►Jimmy Manness takes his new Iron XR to fast qualifying time at the first 750cc dirt track National of the season, the April 19, 1970 Palmetto GA HM.
He is the top Harley in the final, finishing fifth.


►Mark Brelsford is fast qualifier at the July 26 Santa Rosa Mile.
He rides a KR, not the new XR.

►August 30, 1970: Dick Mann breaks his leg at the Sedalia Mile when someone runs over his foot as they race at the front of the field.
He finishes 18th in the final.
Dick entered the race second place in Grand National points, but was third after the race.
Dick skipped the September 7 Indy Mile, but loaned his bike to Dave Aldana, who won.

►September 13, 1970: Jim Rice crashes after the heat race at the Sacramento Mile when his BSA Rocket III hits a false neutral going into turn one.
He breaks his nose in the crash, but finishes 15th in the final.
Jim entered the race with the Grand National point lead, but the title was awarded to race winner Gene Romero.

►On February 27, 1970, the AMA approves the Harley-Davidson XR, a 750cc V-twin overhead valve engine, for Class C competition. It had been tentatively approved in 1969 a the "750 Sportster", but it lacked having 200 units available for inspection at the time. It is later dubbed the "iron XR", due to its steel cylinders and heads.


►On February 27, 1970, the AMA approves the Yamaha XS650, a 650cc parallel twin overhead valve engine for Class C competition.


►On June 26, 1970, the AMA approves the Triumph T120/RT, a bored-out 750cc version of their 650cc parallel twin engine, for Class C competition. The engine helps propel Romero to the Grand National title.
Don Castro and Gary Nixon debut the bike at the Columbus, Ohio National on June 28. Neither make the final.
In the article "The Glory Trail" published in Motorcycle Sport Quarterly, Gene Romero recalls having "our new 750s" at the July 18 50-Lap Ascot TT.

►BSA s David Aldana claims BSA teammate Jim Rice s BSA twin at the August 30, 1970 Sedalia Mile, but does not take possession of the motorcycle.
Backstory: At Sacramento 1969, BSA really wanted Aldana to beat Don Castro (Triumph) in the Amateur final. BSA tells Aldana to ride Rice s TT bike. Aldana wins, and realizes that Rice s TT bike is much faster than his best bike. In 1970, as an Expert, Aldana s bikes are still slow. At Sedalia, Aldana was complaining to Gene Romero and Chuck Palmgren that the only way he'd get a faster bike from BSA is to claim one from Rice. Aldana doesn t have enough money, but the three of them pool their resources. Aldana claims Rice s bike. Rice complains to Pete Colman (Head of BSA racing), who refuses to get involved. The AMA referee says that teammates cannot claim each other s bikes, but Aldana points out that this is not what the rule book says. Aldana wins the claim, but then decides against taking possession of the motorcycle.

(1970 AMA Professional Competition Rule Book, Chapter III, Section A.4.b. Page 6).

►"We, the undersided, qualified members of the Competition Congress, vote "No" on the question of 750cc for road racing. The AMA has, and should continue to be, primarily interested in safety in racing. The aspect of materially increased speeds on such courses as Daytona, Florida and Talladega, Alabama presents a very real threat to safety in racing. In out opinion, to adopt this rule without thorough and exhausted study is not wise.
We propose that a task force be formed under the direction of the Competition Congress to study this proposal and to form guide lines as to courses, speeds, equipment and aerodynamics involved. Recommendations are to be made to the Congress so that a knowledgable fact-founded decision can be made."
Motion by John Harley that the above position paper be included in the minutes. Seconded by Dick O'Brien.

This was the first attempt to race the bike, according to Pete Colman, director of the BSA-Triumph racing program.

►Camel cigarettes sponsors three Grand National events - Laguna Seca Road Race, Santa Fe ST, and Terre Haute HM.
Camel pays $15,000 into the three-race series in 1974. Ten riders benefit.

[1992 Camel Pro Series Media Guide, Page 11]

►Rob Morrison is protested by several riders following the July 7, 1974 San Jose Mile, where he finished fifth.
The AMA reprimanded Morrison for rough riding, but did not formally punish him.

►Gary Nixon races in his final dirt track Grand National on May 19, 1974 at the San Jose Mile.
Nixon races a Kawasaki 750cc two-stroke triple built by Erv Kanemoto.
Nixon does not make the final.

1972 Grand National Champion Mark Brelsford competes at the season opening Houston Astrodome races. He finishes 8th at the TT National, after winning his semi.
He finishes 16th at the spring San Jose Mile, 18th at the Loudon RR.
At the June 23, 1974 Columbus HM, he crashes in semi #2 along with Dick Mann and Dave Atherton, suffering a badly broken leg along with other injuries.
Brelsford would suffer complications from the injury, ending up in intensive care, and nearly dying. After suffering through another long recovery, he retired from racing.

►In order to be approved (for Class C competition) a motorcycle must be a standard catalogued production model and at least 200 of the same model with identical engines and transmissions must be available for inspection and purchase within the United States.
(1974 AMA Professional Competition Dirt Track Rule Book, Chapter XIII, Section A.3, Page 31).
[Comment: 1974 is the final year (since 1969) where 200 identical motorcycles are required for approval].

►The AMA approves the Yamaha TZ750A, a 700cc water-cooled four-cylinder two-stroke engine, for Class C competition.

►For Expert and Junior riders the minimum piston displacment shall not be less than 251cc two stroke multi cylinder engines; 361cc other types of engines; and the maximum piston displacement shall be 750cc.
►Novice riders are limited to equipment with maximum piston displacement of 250cc for two stroke multi-cylinder engines and 360cc for all other types.
(1974 AMA Professional Competition Dirt Track Rule Book, Chapter X, Section A.1, Page 25).
(1973 rules only limited Experts & Juniors to 251cc minimum displacement).

►Maximum piston displacement shall not exceed 250cc for two stroke multi-cylinder engines and 360cc for all other types of engines.
(1974 AMA Professional Competition Dirt Track Rule Book, Chapter X, Section B.2, Page 25).
(Same as 1973).

►For Expert and Junior riders the maximum piston displacement is 750cc.
►Novice riders will be limited to equipment with maximum piston displacement of 250cc for two stroke multi-cylinder engines and 360cc for all other types.
(1974 AMA Professional Competition Dirt Track Rule Book, Chapter X, Section C.2, Page 26).
(750cc is a new rule. Experts & Juniors/Amateurs had been allowed 900cc since 1963)

►Most Novices hold new numbers between 70 and 299 followed by their new district letter.
►Juniors and Experts continue to use single-digit and two-digit numbers followed by their new district letter.
►Some of the district letter reassignments are:

►California loses "X", gains "E", and retains "R", "Y", and "Z".
►Illinois loses "S", but retains "P"
►Michigan changes from "E" to "X"
►Oklahoma changes from "M" to "G"
►Wisconsin changes from "G" to "K"
►One plausible explanation is that scoring was challenging when bordering states had similar-looking letters.
Prior to the change: Michigan/Ohio had E/F, Oklahoma/Texas had M/N, and Southern California had X/Y.
After the change: Michigan/Ohio had X/F, Oklahoma/Texas had G/N, and Southern California had E/Y.

►AMA stops issuing dirt track numbers (with district letter) to Expert riders with Road Race only licenses.

►National Number 1 continues to be reserved for the defending Grand National Champion
►National Numbers 2 through 9 are now reserved for former Grand National Champions
►National Numbers 10 through 99 are assigned on an annual basis, with most riders choosing to keep the same number year after year.
(same since 1972)

►Motocross (MX) racers receive their own National Numbers for the first time in 1974.
(Cycle News, Nov 13, 1973 issue)

►"To earn a National Number for the AMA's Grand National Championship circuit (half mile, mile, road race and short track)[sic] a rider must finish in the top 65 in National points or finish in the top 25 in combined points."
(Cycle News, Nov. 13, 1973 issue)

Per historian Bob Herrick, the "Combined Points" is the sum of the "National" advancement points plus the Regional points earned in the three regions.

The 1974 AMA Competition Congress considers adding restrictors for 750cc bikes at Grand National road racing events, but decide against it.

►The first-ever sound level limits for outdoor professional racing are implemented for the Golden Gate National in Albany, CA: 92dba at 50 feet.

►Grand National road racing events begin running a Superbike class featuring production-based motorcycles.

►Honda wins its first dirt track National (Mike Gerald at Houston, TX short track event)


►The Daytona 200 is shortened to 180 miles due to the national fuel shortage.

►Triumph wins its last half mile dirt track National (Mike Kidd in Columbus, OH)


►The Regional Championship point system is modified.
"Regional points in 1974 will be similar to the Grand National points, being paid for the finals only. Riders will receive full points for events in their home region, however, only one-third of the points won in any other district will be applied toward his total." (Motorcycle Weekly 11/19/1973)

►Camel cigarettes sponsors the Grand National Championship as the Camel Pro Series.
Came pays out a $75,000 point fund in 1975. Thirteen riders benefit.

[1992 Camel Pro Series Media Guide, Page 11]

►40 points to advance from Novice to Junior.
►80 points to advance from Junior to Expert.
If a rider has 95% of the points required and a minimum of two years in that class, with a good safety record, the rider could be advanced to the next class at the option of the AMA.
(1975 AMA Professional Competition Dirt Track Rule Book, Chapter VI, Section A.1.a, Page 11).

►In order to be approved (for Class C competition) a motorcycle must be a standard catalogued production model and at least 25 of the same model with identical engines and transmissions must be available for inspection and purchase within the United States.
(1975 AMA Professional Competition Dirt Track Rule Book, Chapter XIII, Section A.3, Page 32).
(The quantity requirement had been 200 complete motorcycles since 1969).

►The 200 motorcycle requirement (from 1968/1969) was to ensure ample quantities of a motorcycle existed, to maintain the spirit of Class C racing.
Norton wanted to get into Formula 750 racing, but Norton-Villiers-Triumph was struggling to survive, and building 200 units for racing was not practical.
Norton lobbied the ACU (Auto-Cycle Union) in the UK, who went to the FIM, who brought it to the AMA.
This rule allowed Norton to use their short-stroke twin in Formula 750 racing, but also allowed Yamaha to introduce the OW72 in 1976, the XV750 in 1981, and allowed Honda to later develop the NS750 and RS750.
Note: Harley-Davidson had built 200 versions of the Iron XR in 1970, and 200 versions of the alloy XR750 in 1972.
Triumph had built 200 versions of the T120/RT in 1970.
Yamaha had built 200 versions of the TZ750A in 1974.

►On August 28, 1975, the AMA approves the Harley-Davidson MX250 single-cylinder two-stroke off-road motorcycle for Class C competition.


►The AMA approves the Yamaha TZ750B - a 750cc version of the four-cylinder, two-stroke TZ750A that it introduced in 1974 - for Class C competition.

►All sanctioned meets shall be considered claiming meets and the claiming price shall be as follows:
Lightweight Dirt Track Machines $2,500
750cc Dirt Track class $3,500
(1975 AMA Professional Competition Dirt Track Rule Book, Chapter XVI, Section 1, Page 45).

►Steve Freeman claims Corky Keener's Harley-Davidson XR750 at the 1975 Louisville Race Of Champions.
The engine was a special mile engine built by Nick Deligiannis.

►Jim Wright (Junior #44E) claims Ted Boody s (Junior #84X) Bart Markel-built XR at the September 26, 1975 Ascot HM. Boody had won the Junior main; Wright finished fifth. Ted contacts Markel, who tells him the XR is worn out and to let it go. The following night, at the Ascot Grand National HM, Jim rides the claimed XR while Boody rides Wright s Yamaha 750. Wright does not make the Junior main event, while Boody places tenth.

►The AMA 1975 Competition Congress considers a proposal to limit the amount of fuel used during each race.
Had the proposal passed, two-stroke engines might have been eliminated from racing altogether.
The motion fails, 32-23.

►Mark Williams crashes in practice at the September 21, 1975 San Jose Mile National and is paralyzed from the waist down.

►Frank Gillespie crashes in a semi at the September 21, 1975 San Jose Mile National and sufferes a serious head injury as well as several broken bones.
Frank is in a semi-conscious state at the hospital for over a week.

►"Al Gunter, #3E of Chatsworth, CA, is fully conscious and in stable condition at Gardena Community Hospital following a September 12 (1975) spill at Ascot where he suffered a spinal injury."

Motorcycle Weekly, October 20, 1975 Issue, Inside Line (Racing News).
[Comment:Gunter was former National #3, who retired after the 1967 season. He returned to racing in 1974. The 1975 Ascot crash left him paralyzed from the chest down. His AMA Hall of Fame bio reports that he took his own life in March 1976.]

►Equipment used on hard surface indoor competition must be fitted with a muffled exhaust system, meeting a standard of 92 dB on the "A" scale at 50 feet.
(1975 AMA Professional Competition Dirt Track Rule Book, Chapter X, Section B.3., Page 25).

►Camel cigarettes sponsors the entire Grand National Championship, the first series sponsor in history. The series is renamed the Camel Pro Series.


►Harley-Davidson skips the Daytona 200, feeling the XRTT as uncompetitive on the longer Road Race courses. They would, however, compete at Loudon and Laguna Seca, which are shorter Road Race courses.


►Santa Fe Speedway reconfigures its TT course for the 1975 season.
The original course landed off the jump, turned right and then followed the short track course through turns 2-3-4.
The new course goes straight after first jump, through a right hand 180 turn around a light pole, over a second jump, and then a left hand turn onto the back straight of the short track course.

►Scott Brelsford wins the AMA Expert Regional Mile in Stockton, CA on July 6, 1975 on an Irv Kanamoto-tuned Kawasaki H2 triple. It is the first-ever AMA dirt track win in history for a two-stroke multi-cylinder engine (albeit not a Grand National).

►Kenny Roberts wins the Indy Mile on August 23, 1975 on the Yamaha TZ750 four-cylinder. It is the first-ever AMA dirt track Grand National win in history for a two-stroke multi-cylinder engine.

►JR Rawls finishes 7th on a factory PDV (Power-Dyne) at the April 12, 1975 Dallas Short Track National. It was the highest finish ever for a PDV machine.

►Corky Keener, already a factory Harley-Davidson team member for 1975, splits with Bart Markel and moves in-house at the Harley-Davidson factory team starting at the June 7, 1975 Louisville Half Mile. Cycle News East reports: "Corky Keener and Bart Markel have gone their separate ways. The Keener-ridden/Markel-prepared H-D combination was almost unbeatable last year, but reported friction between the two caused the split. Keener will reportedly receive direct help from the factory, while Markel, at least at the May 31 Northville Downs rainout, has Junior Ted Boody on his bike." (Cycle News East, June 10, 1975).


►Harley-Davidson unveils an updated version of the XR750, with improvements over the 1972 model.
The new frame is a copy of the Jim Belland frame which Mark Brelsford used to win the 1972 Grand National Championship.

►Midd Kidd wins the televised Race of Champions event at Louisville Downs on October 12.

►Five TZ750 dirt trackers with Champion frames were built.
They were ridden by Kenny Roberts, Skip Aksland, Randy Cleek, Rick Hocking, and Steve Baker.
The first one was raced by Rick Hocking at the weekly July 25, 1975 Ascot HM.
Hocking qualified third fastest, but did not make the Expert final.
Roberts won the August 23, 1975 Indy Mile on one.
Roberts practiced the TZ750 (but did not race it) at the September 7, 1975 Syracuse Mile.
Roberts raced it at the September 21, 1975 San Jose Mile (he crashed in practice, made the main, put DNF'd with a destroyed rear tire).

►The AMA Competition Committee met in the fall and voted to limit all dirt track engines to single and twin cylinder only. The AMA Board met "a week later" on October 7 and approved the measure. Since the rule change did not affect displacement, the rule went into effect on January 1, 1976.

►Yamaha, Kel Carruthers, and Kenny Roberts were in favor of the ban on dirt tracks for safety reasons.
Roberts himself stated in an interview that the high speed differential on the straights between the four cylinder two-strokes and the four-stroke twins (25-30 mph by his estimates) left no room for error.
"It became immediately clear that someone was gonna die riding such a bike, or cause someone else to die. I wasn t interested in either option...."
(From "The Roberts Chronicles", originally printed in Motorcyclist magazine, reprinted in the September 2021 American Motorcyclist magazine).

►Triumph ceases its factory dirt track effort after the 1974 season as the company nears bankruptcy. The dirt track team is merged into the Norton-Villiers-Triumph squad. Triumph engines continue to be produced in very small quantities until 1983.

►Norton-Villiers-Triumph ceases its factory team on August 1, 1975.

►The September 12, 1976 Syracuse Mile is shortened to 20 laps due to tire wear concerns.

►In order to be approved (for Class C competition - editor) a motorcycle must be a standard catalogued production model, one complete motorcycle, produced, race ready, and at least 24 identical engines and transmissions must be available for inspection and purchase within the United States.
(1976 AMA Professional Competition Dirt Track Rule Book, Chapter XIII, Section A.3, Page 33).
(In 1975, 25 complete motorcycles were required).

►On May 5, 1976, the AMA approves the Yamaha XS-DTC (aka "OW72"), an updated version of the GXS-1 750cc parellel twin engine, for Class C competition. The bike debuts at the May 16, 1976 San Jose mile, with Kenny Roberts and Skip Aksland on board. Roberts makes the final, but the team is unable to get the bike to fire before the race starts.


►On June 8, 1976, the AMA approves the Harley-Davidson MX360 single-cylinder two-stroke off-road motorcycle for Class C competition. It is a bored & stroked version of the MX250. The factory Harley team debuts the bike at the August 13 Santa Fe ST National. Jay Springsteen finishes second.


►Goodyear introduces the DT-II second-generation tire specially designed for dirt track use. The tire - originally offered in 3.50x19 size - is based on the road race 'rain tires' that Kenny Roberts tried on some dirt track events in 1975.
Supply issues resulted in the tires being outlawed at some AMA Grand National events, for fairness reasons.
Compounds are A-34 (soft), A-5 (medium), and A-17 (hard).

►Expert Larry Zumbrun (#77F) attempts to claim Ted Boody's factory XR at the June 26, 1977 Columbus Half Mile. Cycle News reports: He waited, upon advice from Gary Scott, until the last minute to make the bid, hoping to have no counter claims. There were a bunch from Jay Springsteen, Corky Keener, Kenny Roberts, Chuck Palmgren, and Boody. In the end, all but Boody s were disallowed by Eastern Regional Referee Charlie Watson for one technicality or another. The issue was further clouded by discussions on the interpretation of the claiming rule. Protests and appeals followed with the AMA taking charge of the engine until the mess is finally settled."

►Springsteen led Eklund 276-275 entering the Ascot HM finale.
Springsteen won, with Eklund right behind in second, to take the title.

►The July 30, 1978 DuQuoin mile is stopped after 20 laps due to rain. Hank Scott is declared the winner.

►Steve Eklund takes a 17-point lead into the Syracuse Mile (9/10/78). He crashes during the final practice session. He drops out of heat #1 on lap 5 with a broken ignition wire. Because only 41 riders signed up for the 48 spots, Eklund's 9th place heat race finish was enough to advance to the semis.
From Cycle News: "Eklund and his tuner decided to change engines after the semi. Unfortunately, the AMA decided to flop the program due to approaching darkness and/or bad weather - run the National and then the Trophy Race - and Eklund was caught in a time squeeze. Eklund rolled to the line still working and requested an additional two minutes before staging. Other riders were also working - Jackie Mitchell, Mike Kidd and Don Bailey. Eklund, according to referee Charlie Watson, used up his two minutes and according to the rule book was DQ'd. The bike was running almost immediately after the two minute call, but it was too late."

Cycle News continued: "The starting grid for the National looked like a battle zone. Faced with the reality of running the National before the Trophy Race, many riders went to the line - especially those from the semis - less than ready. Steve Eklund was one. His engine change had been caught mid-stride, and although finished, still needed some final adjustments before he could run. The versions of the story vary, but when Eklund was told his two minutes to work on the bike were up, others were still working, and his bike was ready and running moments later. Referee Charlie Watson wouldn't let him ride. 'I can't believe it' said Eklund later. 'All that work for nothing. Then, when I tried to discuss the matter after the race, I find that they wouldn't take my protest because they said time had run out'. Eklund had to go through the pits to scrape up enough cash to be in a position to file (a protest)."

Steve scores 0 points, while Jay Springsteen wins the race to earns 20 points and take a 3-point lead.
Jay would hold the point lead to score his third title at Round 28 by 5 points over Eklund.

Yamaha's Kenny Roberts attends the Houston Astrodome races, but does not compete.

►While not part of the Grand National Championship, there was a tire controversy at the Memorial Stadium short track races. Goodyear had brought twenty-three special "2381" tires to the Houston Astrodome races in February. Terry Poovey bought a couple; Mike Kidd bought the rest. Billy Labrie later recalled that by the time anyone else found out about them, they were all sold. The ultra-sticky compound worked great at the slippery Daytona Stadium short track. Several racers - Gary Scott and Billy Labrie among them - threatened to protest the Daytona event and walk out. The AMA referee Freddie Ephrem insisted that there was nothing in the rulebook to prohibit using the tires, and he threatened to suspend any rider who protested. Gary Scott was briefly detained by Volusia County Sheriffs. Mike Kidd and Terry Poovey finished 1-2 with the special tires. Third place was a full straightaway behind. The next day, the AMA announced that the tires were illegal.

►Harley-Davidson disbands its in-house race team as a corporate cost-saving measure. The factory riders keep their equipment and salary, but the bikes are no longer maintained in-house. The riders are encouraged to hire their own tuners. (Cycle News, January 16, 1985)

►Scott Parker hires Bill Werner as an outside contractor to build & tune his Grand National equipment.
Their first race together as a team is Louisville, 1985.

►AMA introduces the Pro-Am sanction, which enables amateur, Novice, and Junior riders to accumulate advancement points towards Junior and Expert while competing at amateur events.

►AMA changes the number plate layout to return the district letter to the lower right hand corner (where it had been from 1933 until 1983).

►The Novice division changes to red number plates with white numbers and district letters (had used white number plates with red numbers and district letter since 1971).

►Tire Controversy At Springfield

"The tire controversy on the Camel Pro circuit continues. Carr's Continental tire 'threw rubber off in three different places. Mert and I went with the Continental while everyone else went with Goodyear' said Carr. Carr's rear wheel and tire were removed immediately after the race and spirited away, reportedly by Continental reps."

(Cycle News, Sept 10, 1986 issue, concerning the Aug 31 Springfield Mile).

►Parker TT's the XR at Peoria.
Scott Parker elects to ride the XR750 at the Peoria TT - "a move that proved very popular with the pro-Harley crowd" [Cycle News East]. Parker finishes third in the fourth heat (behind Ricky Graham and Jon Cornwell), and was running sixth in the final when he crashed in turn 3 on lap 4. He makes the single-file restart, and finishes 11th.

Editorial Comment on Parker's XR Ride At Peoria 1986:
►Parker finished third at Peoria on the XR in 1984. In 1985, he practiced the XR, but ultimately rode the Rotax. In 1986, he rode the XR. Possible reason was that in 1986, single-cylinder engines were limited to 600cc for the first time. In 1985, they could displace up to 750cc, and both Honda and Wood-Rotax had 660cc engines approved for competition. My guess, then, is that Parker felt that the XR was no match for the 660cc singles in 1985, but he felt he had a shot against the 600cc singles in 1986. In the TV broadcast of the event, Dave Despain comments (during the red flag), that Parker "prefers the torque" of the XR. Parker's long-time tuner, Bill Werner, has mentioned (to me, and others) that both Parker and Springsteen "hated" the Rotax singles.

►Junior division twin-cylinder engine restrictors are increased to 28.5mm diameter (had been 27mm since 1980).

►Effective April 1, 1986, any approved single-cylinder engine above 600cc must use a 38mm or smaller carburetor.
(Referee Bulletin #86-5A dated February 7,1986)
►Ron Wood shows up at a race with a 660cc single-cylinder engine with two 38mm carbs attached.
The AMA does not allow the motorcycle to compete, as it violates the spirit of the new rule.

►Effective January 1, 1986, the AMA will not approve for dirt track competition any newly-submitted engines with displacement exceeding 600cc. (Referee Bulletin #86-5A dated February 7,1986)

►Effective April 1, 1986, any currently approved single-cylinder engine may be converted to 600cc by altering the bore - but not the stroke - of the approved version. The originally approved crankcase, cylinder, and cylinder heads may be altered, but not replaced. (Referee Bulletin #86-5A dated February 7,1986)

Editorial Comment on the Pro-Am numbering system:
►This was a debacle. Almost immediately, conflicts revealed themselves as two (or more) riders in a region requested the same number. One of those two had to be assigned a new number, which inevitably conflicted with another rider.

►It was also confusing for long-time dirt track fans, who were used to letters indicating a specific home state for each rider.

►It allowed riders to compete with a "0" as the first digit on their number plates, and also allowed letters like "I" and "O" to be used.

►AMA memo dated April 1, 1987 states that all Expert division twin-cylinder engines at all Pro Racing events must use 33mm restrictors (previously unrestricted). The official explanation cites the move as a 'cost saving' measure due to concerns about engine failures. But tire wear was a significant issue at the time as well.

►Junior division twin-cylinder engines must use 29mm restrictors (up from 28.5mm since 1986).

►May 4, 1987: 'The AMA Dirt Track Advisory Board voted 5-4 at a meeting in San Jose, California to retain the restrictors. The action was taken following extensive discussion on the controversioal issue after veteran tuner Tex Peel proposed a resolution to remove manifold plates from all Expert class 750cc motorcycles as soon as possible. The restrictor rule generally is disliked by riders on the National circuit.' (Cycle News, In The Wind, May 20, 1987)

►Entering the San Jose round, Parker led Carr 226 to 198. Parker won San Jose, with Carr 8th, to allow Parker to clinch the title by a 246-205 margin with one round remaining.

Syracuse Mile Rains Outs:
►The September 10, 1989 Syracuse Mile rains out. The Camel Challenge is run to completion, but the National is rained out on the sixth lap.

►American Honda ceases its factory dirt track effort after the 1988 season, instead using its 1989 budget to finance Bubba Shobert's Grand Prix effort.

►Former Grand National Champion Bubba Shobert is critically injured at the World Championship U.S. Grand Prix on April 16, 1989. He never races a motorcycle again.

►Kelly Myers is 'Miss Camel' for 1989.

►The annual Daytona Bike Week short track races move from Memorial Stadium to Municipal Stadium.

►The AMA approves an updated version of the Harley-Davidson XR750, after inspecting 25 complete engines on pallets. Improvements over the 1980 version include, but are not limited to, the D-port cylinder heads, ignition, crankcases, oil pump, and cam cover. Harley-Davidson does not offer complete motorcycles, as they did in 1980.

►Grand National Championship half mile and mile events are limited to 750cc twin-cylinder four-stroke engines.

Editor's note: The rule is a direct reaction to the growing competitiveness of the Rotax 600cc single cylinder engines, especially at half mile events. Rookie Expert Kevin Atherton finished sixth at the Ascot HM, beating (among others) AMA Grand National Champion Bubba Shobert. Below the Grand National level, AMA Pro events continue to run 600cc singles and 750cc twins together in the Junior and Expert divisions through the 1992 season.

Editorial note: At the time, Harley-Davidson was providing a signficant amount of contingency for GNC HM & M results, whereas Rotax was providing $0.

►Entering the final round at Sacramento, Parker led Carr 229-218 in points. Parker won Sacramento, with Carr 4th.

DuQuoin Rain Out:

►The July 22, 1990 DuQuoin Mile rains out. The rescheduled event runs on July 29, 1990. It rains out on the second lap of the final.
No points are awarded; riders are paid based on grid position. Chris Carr was the polesitter.

►Will Davis (#21) claims Scott Parker's XR750 at the June 17, 1990 Albuquerque Mile. Parker's bike dropped a valve during the race, which ruined the engine. Parker's tuner, Bill Werner, offered to give Will a servicable engine from Parker's spare, but Davis declined. The engine was using new titanium valves and by surrendering the engine the team lost the ability to learn what had failed.

►Paige Thomas is 'Miss Camel' for 1990.

►Responding to requests from dealers and tuners, Harley-Davidson begins shipping XR750 engines disassembled, with some parts incomplete, if desired. Previously, tuners received a completely assembled engine from Harley-Davidson, and then had to disassemble it and then modify parts as needed. For example, if they disliked the factory cam settings, they needed to remove the cam shafts and grind the welds off in order to relocate the cam lobes. By shipping the engines disassembled, with some parts incomplete, the tuner was saved a considerable amount of effort. In some cases, the cam lobes and gear were separate from the cam shaft, and in other cases the heads were unported.

►Harley-Davidson XR750 and Honda RS750 must each weigh 315#. (XR750 had been 300# limit while RS750 has been 320# limit since 1988).
