Advanced Bi-Metallic Liner. This process uses a double layer of
plating material, rather than one thicker layer. This helps the
metal to bond to the cylinder, and is more durable. Also, the
plating process is more consistent, resulting in a more precise
fit between piston and sleeve, for better compression, longer life.
Two Crankshaft Ball Bearings
