This bike was completely stock when I bought it in San Diego.  The person I got it from said that it belonged to his neighbor that was moving.  says he never road it ? I turned it into a bike that could complete in vintage motocross races..   Have only ridden this bike 2 times since going through it.  Once on a Saturday for a hour to test it out and then the next day at a vintage motocross race at Glen Helen. This bike was 2 into the first turn both moto's and then went on to win its class.  Selling it because now I have 1979 Can-Am 250 that I can race in the same class.  Bike is a little hard sometimes going into first gear into a tight turn but other then that that is runs great.  Thank you
