Lost when it comes to jetting!

[Pjmack54]

I am looking for a little help. I have a 06 yfz with a 12 to 1 piston, 3 mm stroker crank, cam mod, removed spark arrestor with stock exhaust, and a k&n velocity race intake kit. I am wondering what to start with for jetting, I can probly get most of it figured out, but just need to be pointed in the right direction on getting started.

Maybe you should re-read his post....

I started at a 170 main and went down to a 168 on mine but I'm at 4500 ft. Mine has ESR intake Cam Mod and baffle out and the 168 main and 48 pilot work great for mine. It's a little on the rich side at my house but perfect when I get to the dunes. Don't know if that helps but I gave it a shot. :ermm:
