It depends on your airbox and elevation too. Even knowing that no one can tell you the EXACT jetting but can get you close.

any air box mods? If you dont have any mods to your air box, run 150/155. Air-Fuel screws are 2 1/2 on the left and 3 on the right. I never touch my air fuel. (If you do have an open airbox run 180/185 jets in this cold weather with your needle on the 4th clip. If it pops lean move your needle to 5 and you'll have it. good luck!!

how many? how big? do you run a K&N or high flo filter? If you have big a$$ holes or cuts with a high flo, start @ 160/165, if it falls on it's face and doesn't want to run work your way down 155/160 and so on till you find the combo you like best. If you just about have it but it pops lean lift your needle up from 3 to 4 clip.

If they are little holes with a stock filter go 150/155 with the needle on 3, if it pops lift your needle up to4
It will get you close enough to dial it in?? good luck
