Good To Know

Q: Are these intake valves the same as OEM? A: These are aftermarket replacements designed to meet or exceed OEM specifications, but they are not original Yamaha parts. Always verify your model year and engine type before ordering.

Q: Do I need to replace exhaust valves at the same time? A: While this kit only includes intake valves, it is recommended to inspect exhaust valves during a top-end rebuild for even wear and optimal performance.

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