I put an Alba pipe, pro-flo filter system, and no air box lid on mine. I had to go down one size on the pilots, and up 2 on the main. Don't forget the left carb is the lean side, the main jet is one size smaller than than right. I would imagine with an aftermatket cam with a longer duration, you'll need to go up at least two sizes on the main. That should give you a starting point, then see how she runs.
