I have an 04' YZ450 stock. My buddy just bought a new Yamaha FZ600 and we have a bet going. I belive I can kill his bike in a short distance drag race, like 1/8 mile or 0-60. He doesn't think so. Does anyone have any opions on which bike would win such a race? I have a stock 48 tooth sprocket and a aftermarket 40 tooth sprocket. My plan is to use the 48 sprocket and take off in 2nd gear off the line. Does anyone have any other tips that won't cost me alot of money so that I can win this drag race?
