My '01 banshee shoots a blue flame out the right exhause about 4-5 inches. The guy I bought it from hard the top end torn apart do to a busted piston so I have no idea how it ran before. I replaced the whole top end and bearings in the bottom end. The cylinders looks fine and checked out to be standard. I replaced the needle and seat in the carbs also since they wouldn't seal off. It's hard to start, won't idle figure the carbs need adjusted but afraid to let it run to long with the flame shooting out the one side. This is my first 2 stroke so I don't know much about them.
