Beeber, our 2003 XR50R, has a subtle engine noise that I feel may be a sign of trouble. In this video we try to figure out what is causing the sound, and in the process disassemble and inspect the clutch assembly. The sound seems to be coming from the transmission or crankshaft area rather than the valve train, piston, or cylinder. Millions of these 50cc Honda engines have been produced. They were used in the Z50, XR50, and CRF50 which is still in production as of 2024.
