JOHNNY TONY KART First start of engine Rotax Max

[SuperNeckerman]

i think the damage comes in when you overrev the engine

that happens when you don t have a load on it ex. on a kart stand and pressing down the throttle all the way

your not ment to rev 2 stroke engines un loaded EG: on a stand you seariously damage the engine

@BoyRacer224

there is no problem with this. you can purr it in this position without damaging the engine, it's just warming the engine up! ;D
