          Advanced Bi-Metallic Liner process uses a double layer of plating
            material rather than one thick layer. This helps the metal bond to
            the cylinder and makes the plating more durable. Also, the plating
            process is more consistent, resulting in a more precise fit between
            piston and sleeve for better compression and  longer life.
          Angular head design offers increased surface area for better cooling
          Muffler includes straight and 90° adapters-no need for expensive
            aftermarket mufflers
