This is my 6th bike. I know banshees pretty well. I have s very hard sputter from 1/3 to full throttle. Bought bike real cheap. New reeds, cleaned the carbs, new air filters and even checked the gap on the pick up on the flywheel. I'm lost. I changed the mains and the pilots as well as adjusted the needle. I'm starting to think its electrical and has to do with spark. Gonna do a compression test later to just make sure I don't have a cracked sleeve or bad rings but the bike barely smokes. Any ideas guys???? I can always figure these bikes out and it's pissing me off.. Thanks
