Give you a little background on the bike so far this is what I got I got a set of Vito's stage two carbon fiber reeds I also got a hot rod crank kit The top and was boarded out using a wiseco piston The piston rings bag says 68.25 i'm assuming that's the piston size And I have a pro circuit pipe I need help with jetting and also What sprockets to buy I enjoyed muddying and street riding
