It allows a gain of 5 HP on average which is huge on this vehicle. Enough to have fun on the tracks or in the forest. ATHENA has also planned things well because this top engine is sold complete. It includes the cylinder, piston, ring, cylinder head and all the gaskets you need for a quality and tight reassembly.
