Hey guys im brand new on bansheehq. Just got my first banshee a few days ago. Its a 1999 with full t5 pipes and k&n. When I test rode it, it ran great. So I bought it and took it home. decided to clean everything up. Cleaned the airfilter, powerwashed it and changed the tranny oil and drained the fuel. Previous owner was running yamalube 2s in it at around 28:1, I changed it to Klotz BeNol at 32:1. ever since I did this it has started running bad on that one cylinder, Not smoking as much as the right cylinder and backfiring. I then proceeded to take the carbs off and clean them up. found out im running 240 mains, which I think is to lean. But that still doesn't tell me why one cylinder is running bad. Thanks guys
