Im helping a friend build a banshee, it is tunned properly and sounds good, but when riden, it does not runs as a banshee should (sorry for my grammar, Im from latin america!). I dont know if its because he has mixed parts: This is a 87 banshee with all the electrical parts from a 2003 model, it has 39mm carbs from a 250r, new gearbox from a 87 model, new clutch discs, fmf pipes and exhaust. I think the problem might be on the electrical part or somethinr conserning the carbs or pistons.
Need help, he's about to crack his head!!
comment appreciated!
