Stock Bore Service Kits

The ultimate solution for a complete top-end rebuild for your 2-stroke dirt bike. Crafted with precision and expertise, these kits are designed to elevate your ride and enhance performance.

Our meticulous service begins with stripping your cylinder, inspecting it thoroughly, and performing necessary repairs to ensure optimal function. We then employ our proprietary nickel silicon carbide plating process, followed by precision honing to match the provided stock bore forged piston kit, ensuring perfect piston to cylinder wall clearance for maximum performance.

But we don’t stop there. We also service the power valve assembly and clean and hand lap the cylinder head to better than new condition, ensuring every aspect of your bike’s top-end is expertly cared for.

No need to search for replacement parts; we’ve got you covered. Each kit includes a forged piston, gasket kit, and top-end rod bearing, providing everything you need for a seamless rebuild experience.
