What Comes in the Kit

The package includes a head that arrives already assembled with valves, springs, and seals. The cylinder is cast iron with a 52mm bore, honed to precise tolerances for dependable running. An aluminum piston fitted with sturdy rings handles the everyday load. A full gasket set is also included, so the kit is ready to fit as soon as it is unpacked.

Fitting Tips

For the best outcome during assembly, offset the ring end gaps by 120° from one another. Apply a light coat of 4-stroke engine oil to the cylinder walls to avoid running it dry on first start. The fitting steps are direct, so worn or damaged components can be swapped out quickly to restore the engine's performance.
