Sean, just a couple things. There is no need to start the motor that soon before the start. 15-20 seconds is plenty. DO NOT keep blipping the throttle!!! Just give it enough to keep it running- that’s it! One hard start a day! In other words, take it real easy on it leaving the pits for practice, and only hammer it at the starts of the race. After each event (we actually do it each day) remove the drum, sand the shoes and clean them and the drum with brake clean. grease the bearing and you’re good to good.
