Cylinder Works Cylinder Kit Standard 40004-K02

If you're running a two-stroke engine that's seen significant mileage, a worn cylinder directly kills performance—reducing compression, increasing blow-by, and forcing you to compensate with richer jetting just to maintain baseline power. The Cylinder Works Standard 40004-K02 delivers a complete, ready-to-install solution with matched components and Nickel Silicon Carbide plating that resists wear far longer than standard sleeves. This kit gets you back on the track or trail without the downtime of custom fabrication or re-plating.

• Matched Vertex pistons
• Complete gasket set included
• Piston rings, pin, clips
• Direct bolt-on fit
• No machine work required
