sleeper06 Posted July 5, 2011 Report Posted July 5, 2011 You will get no gain from higher octane fuel unless you raise your comopression,race gas has a slower burn rate and could actually hinder performance on a lower compression machine,i am also guilty of splashing pump gas bikes but run whatever its designed 4 Quote
