im stunting out my 07 cbr 600rr right now and just put the throttle screw from a f2 in...the problem im having is that when I idle the bike up and im in gear ill give it some gas and the idle will get stuck, the more throttle I give it the higher the idle gets stuck. ill kill the bike start it right back up and its back to where I set it. This doesn't happen at regular idle, anyone know what my problem is?
