I have a 2005 f7 sno-pro carb...I just put k&n filters on it replacing the airbox, vforce3 reeds, d&d lite pipe and y pipe and the clutch kit to go with it...the clutch is supposed to go to 7500 r's and climb to 8000, but i can only seem to get between 7100 and 7300 out of it....It also has 520 main jets in it....any ideas whats wrong with it?

I bet 490's would be fine..

i tried 490's and 500's they were too lean...the plugs were very white with those, then i put 530n's in it and it was way a little rich..i have the 520's in it now and the plugs are perfect....
