Go fat on jetting and dial down way better to start fat rich than lean. I would get 520 500 480 460 main jet pack from mikuni they come in sets of 4 for like $12-$15 start extra rich ad work down that's what I plan in doing when I get my motor together. I'll rob ably start around the 580 - 560 range though but I'm running a q pipe and v2 reeds with a 9" k&n so more flow than your setup.
