I know I know, these questions are getting old, but I have never done jetting so I am completely new at this. I have the Yoshimura Full exhaust system, with no other modifications. I plan on leaving the airbox lid on and I won't be able to buy a K&N for awhile. I live in AL so I'm guessing the elevation is below 3000 ft. Are the instructions correct where it says 122.5 main jet? I also want to know what the stock jet is. Please help me as I am in desperate need of assistance.
