I have a friend that has one laying in his garage. A buddie cut it out of his pipe and then a couple months later burned his vavles up. Not enough back pressure on the motor. I dont care what people say! these little motors cant take that. The only motored designed to run open is a harley davidson. Any other will burn up the valves. Seen it done so many times. In my little 250ex my stock baffle screws out. I had it out for a month and my vavles were so miss adjusted. I had to take it in to get adjusted.
