Good To Know

Q: How do I know this valve fits my craft? A: Match the OEM cross-reference 8GL-12121-10-00 against your parts diagram, then verify your model year falls within the stated 2021-2026 range. Confirm against your serial number before ordering.

Q: Should valves be replaced as a set? A: Many builders replace all valves in the cylinder head at once so wear stays even across the engine. Follow your service manual for the correct procedure and torque values.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
