The supplied product is unbranded aftermarket. YX/YinXiang and Zongshen engine names, engine codes and supplier part numbers are provided for identification and cross-reference only. No reliable genuine OE number for this exact complete kit was found, so an OE number has not been invented.
Fitment
Fits many YX150 engines that use the same 60 mm bore and 13 mm gudgeon pin as the YX160 top-end family. Compare the old barrel and piston before ordering.
Important Checks Before Ordering
- Measure the existing cylinder bore — this kit is for the standard 60 mm pattern
- Confirm the piston pin measures 13 mm
- Compare the cylinder height, lower spigot/skirt diameter and cooling-fin pattern
- Compare the four cylinder-stud positions and cam-chain tunnel shape with the photographs
- Check the engine code stamped on the crankcase
- Confirm the gasket profiles match the cylinder and cylinder head being reused
This is a standard-size rebuild kit, not a big-bore conversion. Do not order solely from the bike brand or frame model, because many pit bikes have had replacement engines fitted during their life.
Installation Notes
Top-end engine work should be carried out using the correct workshop procedure. Check piston-ring orientation and end gaps, lubricate the cylinder and piston during assembly, fit the circlips securely, set valve timing correctly and tighten cylinder-head fasteners to the engine manufacturer's specification.
What Is Included
One cylinder/piston rebuild kit containing the cylinder barrel, piston, piston pin, two pin clips, piston-ring set and three gaskets shown in the product photographs. Cylinder head, valves, camshaft, cam chain, engine studs and crankcase are not included.
