$800 Yamaha XJR 400 Revival | Full Engine Rebuild & Classic Restoration

Today we bring back a Yamaha XJR 400 that has been abandoned for years. In this full restoration episode, we diagnose the issues, tear down and rebuild the inline-4 engine, clean and sync the carburetors, refresh the ignition system, and restore the fuel tank. Then we rebuild the brakes, service the suspension, replace worn bearings, and finish with a full detailing and road test.

If you love classic Japanese motorcycles, satisfying deep cleaning, and complete rebuilds from “rusty and dead” to “running like new”, this Yamaha XJR 400 revival is for you.
