The 750 was a Kx Street bike in the 70's. The H2. My teammate races one in a 250 chasis. It has no reeds. 3 carbs, 3 plugs. Pipes were made from 250 pipes, my buddy Paul's is a '74. Parts are getting harder and harder to find, but they do hold up well. A new discovery for paul has been that the guys fixing up Jet-Skis, are working with triple cylinders and cranks alot and have been very helpful getting this year's machine together. Paul has rode the 750 "Triple" in the 750 Class and been the Champ several times. This year he put his back-up engine in a Banshee Chasis. Look out 2 stroke quad class. That will be sick, when he gets it all put together.
