I'm just curious, i just got some 28mm PWKs and am getting ready to jet them into my bike. It has 400cc cub cylinders, 19cc domes, VForce 3's, open air filters, trinity intakes and a Toomey T5 exhaust. I live at Sea level so i put in 160 mains for pilots. What do you guys think? Or should i try something else? Also what do you guys think the needle clip should be set at? Any comments would be great.
