right now i have a 310 main, stock pilots, air screws 2.5 out, Toomey Needle 3rd clip. It ran okay at the dunes but bogged alot mid throttle. I have PT Hi Revs, K&N Pods, VF3's, Coolhead 21cc domes, +4 timing. i am at sea level, and i have heard of some people running 320 mains, even 340 mains. are my mains too low? I was thinking they are because my pipes blued alot during my trip. and do i need to drop a clip on the needle?
