Description

This Blue Line gearbox case gasket is a fresh start for a leak-free gearbox service on compatible GY6 125/150 and 139QMB-based 50/80cc scooters. Replace a damaged or torn gasket when opening the transmission case to help keep gear oil where it belongs and get your scooter ready for the next ride.
