Carburetion, piston, cam, and head work were about the only changes performed by the factory before they were sent to the U.S. for competition, When the engines first arrived one was put on the dynamometer, It recorded 83 blip @ 8500 rpm and all engines are sald to be equal in output. The bottom ends are stock! Transmissions were changed from five ' speeds, as used on the road racers, to four speeds since the extra speed wasn't needed and a small saving in weight could be realized. Three B.S.A.s and three Triumphs are being prepared. Dave Aldana, Jim Rice and Dick Mann will be B.S.A. mounted. Gene Romero, Gary Nixon and Don Castro will be on Triumphs.

CALIF .• July 16, 1970 - The sound of the screaming B.S.A. and Triumph 3's will be heard again this Sunday at the AMA Mile Track National to be held in Santa Rosa, California. These machines are or1g1nally road racers that are now being converted for mile track competition. This may atflrst thought seem strange because dirt track racing and road racing are so dltferent. But surprisingly, as Lloyd Bulmer, techmeal representative for B.S.A.-Triumph explalnM, not all that much has to be changed to make the bikes suitable for the dirt. The frames, speclf1ca11y bu1ltfor road racing, remain as they came from the factory. The front forks have been change, using components from both B.S.A. and Triumph, with the lower fork legs the same as those used on 1969 Victors. The rake remains the same but the trail was altered sllgbtly. A single disc brake is employed in the rear with no brake on the front: Both a foot lever, mounted on the right side, and a hand lever, mounted on the right handlebar, actuate the rear brake - the rider using whichever he feels most comfortable with.
