I bought this 1973 cb500 a couple of years ago from a guy who drag raced it some. When I got it it had not ran for 3 years and the carbs where gone. It had a seat pan but no seat. I made the seat I know it aint great its the stock pan the back I made out of a batting helmet. I painted it red at first and my boys rode the crap out of it.This time I repainted it for me. It runs real good I have no ideal what has done to the motor but its quick for a 500.
