hmm i'll have to check to make sure it doesnt have an air leak. It looks like the left cylinder smokes more of a white smoke and not a blue smoke like it should but the right doesnt seem to smoke much at all. Now I dont know if this would help but I took the left plug wire off and tried starting the banshee and it wouldnt start. then unpluged the right side and it would start on the left cylinder. Thanks guys
