11:1 piston and deck the head or just 12:1 and leave the head alone? i wanna stay pump gas
Haha where I used to live!! Oh wait....IL is just a flatland lol nah not really but central IL is!I would say you could probably run a 12:1 with 93 and be just fine. I ride at 5k or above and run 87 with an 11:1I guess ask guys where you live what compression they are running and what octane. I was just told a lot of us run a higher octane than we really need and we are actually loosing power because of it.

I was just told a lot of us run a higher octane than we really need and we are actually loosing power because of it.I have a friend that rides a banshee that won't shutup about 100 avgas. He mixes his 50/50 with 100 and 91 before oil mixing. I always turn him down. I did finally get to explain the whole compression thing to him, that raptors are built lower for longevity. The extra octane is a waste of money unless you are 12:1 piston or better.
what does the warrior thing have to do with it?
the higher octane than you need does in fact cause power loss.....higher octane fuel is harder to burn.....so you don't get a complete burn = loss of power....
