Ok this is whats up.... 3 weeks ago my friends banshee took a s***..the piston broke and messed up the the crank... it was all replace and fixed by alba... today we got it back and we went riding... we realized it wasnt running good.. now the left exhaust is throwing gas all the way back to the silencer... so we looked at the left carb and found that the rubber seal that attaches to the air manifold was only half on.. so we adjusted it,,but it still runs like crap.. is the carb jets now clogged from dirt getting in them?????? or does the carb have to be replaced???? or is it the cylinder????????
