iWHY? why do you want to do this? Compression is already very high compared to most motor vehicles, Its surprising to me that more people arent putting holes in pistons from detonation and preignition. Gasoline quality widely varies and the numbers on the pumps are almost ALWAYS wrong, not to mention oxygenated fuels with steadily rising amounts of alcohol in the fuels isnt helping.
I could go on about the stage 1,2 & 3 forumlas for tuning and performance but rather than that,,,,,, WHY?
Track bike? other mods at the same time?
