Jetting Question?

Hi All, I was wondering if I could get some recommendations to at least get me in the ball park with my jetting. I ride anywhere from 3,000 ft to 7,300 ft in elevation for starters. Im running my '06 660 with my airbox '04 style with a few more quarter sized hole's in the airbox lid. I have a stock engine and stock exhaust. Any Help is appreciated thanks!

I would start with a 145 main jet and turn in your idle mixture screw 1/2 turn. Run it for 5 to 10 min and see how it feels, then pull the spark plug and see how much fuel your not burning, and unburnt fuel is black not brown. you want atleast 1/8 inch of black from the bottom of the porcelen.

10-4 , Thanks I'll start there!
