I have a banshee and every once in a while it revs up for no reason. The throttle cables aren't snagged on any thing. It also does it when the motor is warmed up. I was wondering if it could be linked to a overheating problem, gas/oil ratio problem, or a jetting problem. The bike has toomey T5 pipes and a boost bottle, I have 270 jets in it and I am running a fuel ratio of 32:1 of klotz and premium gas. If anyone has any advice whatsoever it would be greatly appreciated
