Back when I circuit raced motorcycles they didn't flame so much as made a telltale puff of blue smoke when the rider blipped the throttle and downshifted for a turn.No disc brakes then, so down shifting was all important as the brakes usually faded away halfway through the race.As the rider got tired, he downshifted sooner,good time to turn inside for a pass.
Bikes are faster too with a little oversteer, but ground the frame hard in a turn would generally unload the rear wheel ,lotta oversteer then grin
Tony M,you raced Formula Ford????
