Servo motor, clean PV's
check grounds
anytime there is a problem
unplug everything going to the handle bars and tail light wire at the rotor. That will eliminate most of the electrical system just to make sure its not any of it causing the problem.
I've heard of tail light wires and hand warmers grounding out causing some wierd stuff.
But because of the rpm I would guess servo.
check the fuse too
