There are 2 Cylinder Head versions being factory installed in GY6 scooter engines. They differ only in the valve length. The old version ships in almost all GY6 scooters and has a valve length of 64 mm. The new version has 69 mm.

⚠️ Important Selection Note: Please check your valve length and EGR configuration before ordering. Using the incorrect cylinder head version will result in improper valve operation and potential engine damage.
