Call To Arms

I don't think so Teddy , chuckle chuckle
 We went to a lot of trouble to get it where its not a threat to a Jackpiner, hoping they would let me ride in the vintage class.  with  only 4 inches of travel in the rear its not competitive against the 76 and up machines.
 do you have a pipe for a 72 to 75 six-days?
 all you need is the header and a good front cone. we can send you the  Carl crank pipe mod's for a 100cc mx bike. aircone can role you a rearcone and the center section. I would not  go with the porting mod's in the article as I think they would shorten piston and ring life too much. If you cannot get someone to weld it up for you Peter and I can, we have a 72 frame and can get the pipe welded up to fit right. you would need to add a scliencer when you got the pipe back, but the pipe would fit. it would give some boost in power on the 100 with out shortening the life of the motor.

I have a "trick" pipe made out of aluminum. It's very short. A couple people have told me who made the pipe, but I can never remember it. I will stay with this pipe, it works very well.
