I have just purchased a wb pro meg silencer and header as well as a k&n filter. I plan to also run with the airbox lid removed, so what jetting should i go with? I have no ther mods yet. I live in virginia.

I think AtvMxRider meant to say LOWER the clip (which raises the needle and richens the jetting)
