Engine Stud Kit for CSC Go., GY6 50cc (139QMB) Scooters

Engine Stud Kit for CSC Go Scooters Using 139QMB Engines

This engine stud kit suits CSC Go scooters and bikes equipped with 139QMB engines. It takes the place of the original factory studs and holds the engine firmly in position. It is one of the GY6 50cc scooter parts you might require for routine upkeep or repairs. Every kit includes two long studs for a dependable fit.

Build and Compatibility

The kit contains two long engine cylinder studs, which play a key role in holding the engine assembly together. It works with a range of engines carrying the 139QMB designation. If you intend to swap out all four original engine studs, order two kits.

Signs It Is Time to Replace Engine Studs

Consider replacing the engine studs if you notice engine vibration or whenever the engine has been taken off for any reason. Studs that are worn or damaged may cause the engine to sit out of alignment or allow leaks, so replacing them promptly helps keep the engine running properly.
