Product Details

The WSM Standard Bore Piston Kit is a replacement top-end piston kit for Yamaha watercraft and powersports engines. It is for engine rebuilds on cylinders that are still at stock size. Each kit helps restore factory compression and power, and is built to meet or exceed OEM specifications.

Key Features:

  • Made from high-grade materials to withstand demanding use
  • Built to match OEM specifications for proper fit and engine clearance
  • Helps restore lost compression and performance in worn stock engines
  • Each kit contains a piston with rings, a wrist pin and clips for installation
  • Platinum Series versions use hardened aluminum, designed to resist skirt and ring-groove breakage

Important: These standard bore kits are for stock-size cylinders that have not been overbored. They will not work with overbored cylinders or sleeves.

WSM standard bore piston kits are a dependable choice for a complete engine rebuild or routine top-end refresh. Choose the child item that matches your engine's bore size and application.

NICE PRICE FAST SHIPPING

I had two orders, and needed to return item on first order. Had issues when it came to Getting an RMA. kept getting an Internal error. Multiple try's (a lot) and I was finely able to figure out how! There is no guidance even on "frequently asked questions category" on how submit an RMA request. What made it much harder is there was no phone # to contact Customer Service. NOT Good!!! As far as my second order, I am very happy with the Husky floor mat liners.

Very helpful information that determined my purchase.

Almost to good to be true.... Product on time, Brand new, and a few hundred dollars cheaper than Amazon and other sites... legit

Straight forward, price was good, shipping was fast.
