Yamaha GP-R 1200 Power Valve Gasket Kit
Power valve gasket kit for the Yamaha GP-R 1200 personal watercraft equipped with the 1176cc 2-stroke 3-cylinder triple engine featuring an 80mm bore and 78mm stroke with CDI ignition and YPVS power valve exhaust system producing 155 horsepower. This gasket kit includes all the gaskets needed for power valve service and engine rebuilding. The YPVS power valve system requires precise gasket sealing to maintain proper exhaust timing and prevent exhaust leaks. The 2-stroke marine engine operates under severe thermal cycling which degrades gasket materials over time. Replacing all gaskets ensures proper sealing at every junction and prevents compression and exhaust leaks. Always clean all mating surfaces thoroughly before installing new gaskets and torque all fasteners to factory specification for a reliable seal.

⚠️ IMPORTANT:

This power valve gasket kit fits the 2000 Yamaha GP-R 1200 with the 1176cc 2-stroke 3-cylinder triple engine equipped with YPVS power valves. This kit is specifically for the 66V power valve engine. Verify your part number before ordering.
