G- Transmission Breather Tube (GY6)

G- Transmission Breather Tube (GY6)

Description: Transmission Breather Tube aka crankcase breather tube for GY6 125/150cc 4-stroke engines. The rubber hose with rubber grommet fits directly into the stock transmission crankcase which is located near the rear shock and above the rear gearbox. This is essential for allowing your transmission gear to release air and not build up too much pressure from the churning gear oil. Without having a rear breather you run the risk of debris falling in and damaging your transmission. If you have a GY6, always replace the hose when doing the transmission gear oil change as it rubber can become hard and brittle.
