jetting my 28 keihin pwk

[so_cal_sun]

I have an 02 banshee with trinitys pro mx porting, stage 4 pipes, v-force reeds,spacers, 28 keihin pwk carbs that run 155 mains, pro design cool head with 17cc domes, adjustable stator plate(advanced 1 degree). My bike idles and runs perfect at low end.As soon as I get to about half throttle the RPMs go up but have no power. Will someone please shed some light.

What kind of gas are you running? Why bother with 1 degree of advance on the timing? Why are you running reed spacers... is the clutch arm hitting the bottom of the left carb if you don't have them spaced farther back?

I can answer the question on the reed spacer's yes the clutch arm does hit the carb... try adding more main. try like a 165. for giggles to see what happens.

Hamuel are you running the stock intake boots or aftermarket types?

Im running vp110.I did the reed spacers because it is hitting the clutch arm. The only reason why I advanced to only one degree is because I just replaced the top end was still breaking in the motor at the time. Im running stock intakes

thanks
