Product Overview:
If your cylinder is blown, compression is too low, or piston seizure has occurred, this kit is the ideal solution for you.
The kit includes everything needed for a complete top-end rebuild: cylinder, piston, rings, pin, clips, and top-end gasket kit (exactly as pictured).
The cylinder is made from aluminum with an internal cast iron sleeve for improved cooling performance and enhanced durability.
The piston is anodized for superior heat resistance and an extended lifespan.
High-performance gaskets increase durability and provide greater reliability.
Includes all gaskets shown for a full top-end rebuild.
This kit is designed for a big bore size of 79mm with a 17mm steel piston pin.
Compression Ratio: 11:1.
The compression is designed for use with the original cylinder head. During installation, the smaller bearing on the factory camshaft must be removed and transferred to the new camshaft.
A great low-cost replacement for defects in the original cylinder.
