Good To Know

Q: How many power valves does my LRV DI need? A: The 951 DI engine uses power valves at the exhaust ports, so confirm the quantity your machine requires before ordering. A: Matching OEM number 290854540 to your craft helps ensure correct fit.

Q: When should power valves be replaced? A: Replace any valve that is seized, scored, or heavily carboned, and inspect all of them during top-end service. Consistent valves help keep exhaust timing stable.
