Me and my bud finally got around to racing our bikes. My bike is a 1980 Honda Cb900 Custom, His bike is a 1985 Yamaha XJ750 Maxim, I've got slightly more horsepowers, but my bike is roughly 550 lbs, and his is roughly 375.The power to weight ratio is about 6lbs for me, and 5 lbs for him, and that's not even considering my fat butt. But hey it was a good time, and we made alot of loud noises so yeeyee.
