i have every bolton and need more power. short of swapping a 450, i was thinking some hotcams and a wiseco highcomp 13.5:1 setup....piston and cams made a HUGE difference on my old raptor and hopefully will on this bike also. my only question; can i run on 91 or (93?) pump gas and n0t get the detonation? i heard a while ago that anything over 11;1 is a nono on a 4-stroke? anyone try this?
