I would try a 170 main jet. I think they run a 118 from the factory (or something close to that) My buddy has an 04 with the same mods and no airbox lid with a 180 main, and it goes pretty good.

do you mean it has a 170 main or that you are running a 118. that is waaaay to large of a jump in jetting on a stock bike, i dont care hoe lean it is from the factory.
