I have a CBR RR 05 stunt bike. It's new. And it 's throttle screw won't turn the revs as far as it should. I heard that the F4I one matches and is pretty good. Anybody have any idea about this? It ' s been killin' me these last weeks.

 

Stop playing with the a/f adjustment. You need to do an idle mod.use search
