Ok now im a drag guy and not use to working on almost stock banshee's. I think I know the answer or answers to this but heres the question.
I have a banshee that I think might be ported not sure havent checked, It has fmf pipes and k&n filter with no lid. The problem is, when you rev it up it will back fire sometimes and you can see a flame in the carbs.
Any ideas?
