i got a 06 er. i got hrc head pipe, stock muffler with no spark arester, no airbox lid, stage 2 hot cams, and cut green wire mod. it is jetted and has a adjustable needle too. it runs great on 91 or 93 octane gas but i put 110 race gas in it and it seems like it don't run as good. do i need to rejet or is the 110 octane a waste of money?
