Polini Light Alloy 50ccm cylinder kit.
The cylinder kit is largely complete, however, the original outer top piece must be used.
The kit provides more power across the board, but ensures minimal increase in the load on the crankshaft, making the kit ideal as a replacement for the original cylinder kit if you are looking for a little extra power. A long-threaded spark plug must be used for this cylinder.
