Polini, the market leader in two stroke tuning, have produced this reliable cast-iron kit for everyday use. Will work with the original carburettor although mainjet should be increased by aprox. 8-10%, power output up to 9 Bhp. Remarkable because of its massive bottom end punch, which makes it a wheely addict's premier choice. Comes with gaskets, piston and cylinder-head. We recommend Bosch's W3CC (W3AC) spark-plug.
