Ok guys I really need your help. I cant seem to get it right and need to know some of your opinions. I have a stock banshee with CPI inframes, shaved head with 19cc domes, 2 into 1 K&N Kit, Stock reeds, Bored 20 over, and I use 3 gallons 110 octane leaded with 2 gallons pump gas mixed at 40:1. I started out with 340 main Jet and a 27.5 Pilot Jet and it bogged real bad on the top end. I went down to 320 mains and still boggs bad on the top end. I am afraid of going to lean and blowing it up. can someone please tell me what to do? Am I running the wrong sized Jets or do I need to do something different? Thanks alot for any advice you may have.
