Description
Same mounting dimensions as the O.S. .32SX and .25FX Weighs only 0.35oz (10g) more than the .32SX
Advanced Bi-Metallic Liner. This process uses a double layer of plating material rather than one thick 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.
Newly designed E-3080 Power Box muffler generates mild and pleasant sound and is constructed with an O-ring between the front and rear body to prevent oil leaking and is fully positionable 21K carburetor with needle valve angled toward rear of engine for safer adjustments
Ball bearing-supported crankshaft
