My bike (07 450x) is apart for installing a 07 450R head and maintenance. Before i put it back together i'd like to know if i should go any size up on jets or needle. The jetting i've been running without the r top end was: 170 main 48 pilot 50 leak ncvs #4 The mods: Twinair / no backfire airbox top cut q4 can 05R CAM 07R HEAD Any suggestions on changing my jets before i put my carb back together? If so what sizes? p.s. I'm at sea level from 60 to 95 F. Thanks!
