M6 Exhaust Flange Nut for CSC Go Scooters and GY6 50cc Engines

This M6 exhaust flange nut is a direct-replacement part for CSC Go scooters and several models that use the GY6 50cc engine. It secures the connection within the exhaust assembly, which plays a role in how well your scooter runs. If you are servicing or repairing your scooter, you may want to look at these GY6 50cc scooter parts. It is made to take the place of the original nut without requiring modifications.

Engine Code Compatibility

This nut works with a number of 50cc and 80cc engines, including those marked 139QMA, 139QMB, 1P39QMB, 1P39QMA-2, YN139QMB, JJ1P39QMB, and additional codes. When your engine identifier contains "QM" or "FM," this part should suit your vehicle. Checking that the engine matches helps keep performance where it should be.

Signs It Is Time to Swap the Exhaust Flange Nut

Consider replacing the exhaust flange nut when it shows wear or when you are working on the exhaust system in general. A tight exhaust joint reduces the chance of leaks and helps your scooter run as it should. Routine checks make it easier to spot when a new nut is needed.
