I was at some grass drags a few months ago with a buddy who has a stock banshee with pipes and a cool head. There was Raptors, a Predater, a DS 650, a 400ex, and a V-force which was on nitrous ( but had a huge guy riding it ) and a bunch of other banshees. He easily beat all the four strokes and made it to the all banshee final. Nothing else could compete. Banshees rock, four strokes suck.
You should have no problem kick'n their four stroke ass!!!
