I am building a 79 XR500 mx'er and was wondering if anybody has any tips tricks or ideas that they have used on the suspension or asny custom work they have done on the XR500's. Alot of my friends are getting into vintage racing and so i want to be different from the rest and not ride a 2-stroke like everyone else does. Anybody made a custom swingarm?moved the rear shock mounts on a stock swingarm? Any and all help, knowledge, or information would be greatly appreciated. Here is a pick of the project bike and i will update pics along the way as the build progresses.
