Description
If you’re running a Yamaha GP1200, piston wear directly impacts throttle response, fuel efficiency, and engine longevity. The Wiseco WK1313 restores—or exceeds—OEM performance with a complete overhaul kit that includes rings and gaskets, eliminating guesswork during assembly. Built from high-silicon forged aluminum, this kit handles the thermal stress of 2-stroke watercraft engines while delivering the precision fit that separates a solid rebuild from a bulletproof one.
