Working on a racing engine, it is sometimes necessary to adjust the cylinder height in order to adjust the squish clearance, to obtain the right compression in the combustion chamber, or to optimize the valve timing. That’s why Athena technicians developed the Race Gasket Kit, the engine gasket kit which covers all the most popular Motocross and Enduro applications on the market, both 2T and 4T. The kit includes a cylinder head gasket and two cylinder base gaskets, one with the thickness same as the OEM component, and the other with a reduced thickness of 0.1 mm. Athena has studied for each application the OEM engine to create gaskets which carefully respect the tight parameters imposed by the manufacturers.
