[QUOTE="ossagp, post: 213317, member: 1650"] I still have several the the original xr/xl 500 original motors. Many of the problems I had in building them up into the 45 plus hp range was the chain operated balance shaft. The plate that held it would get distorted. Welding it to build it up seemed to fix a lot. Then you get them built to the point that the output side of the crankshaft would start wobbling under load. But in stock form, they seem to run forever. [/QUOTE]
