11:1 wiseco?

how much pwer does an 11:1 wieco that is .040 over give a 400ex with complete pipe, stage 2 jets, and k&n filter with modified airbox

to get the full effect i think a agressive cam would be in store

yeah it won't give a huge gain unless you put a cam in it.
A 440 kit w/o a cam and pipe is actually slower than a stock 400ex.
