ATHENA Cylinder Head Gasket for KAWASAKI KX 500 1989-2004

The ATHENA S410250001113 head gasket is designed for KAWASAKI KX 500 from 1989 to 2004. The head gasket seals between the cylinder head and the cylinder: it holds in the combustion pressure and, depending on the engine, the coolant. Crushed when tightened, it can never be reused.

Fitting tips

1. Clean the cylinder head and cylinder faces without scratching them.
2. Fit the gasket dry, the right way round, centred on the studs and the coolant holes.
3. No sealant on the gasket.
4. Tighten the cylinder head in a criss-cross pattern, in several stages, to the manufacturer's torque.
5. Refill the coolant and take the opportunity to replace the spark plug.

Frequently asked questions

Is the gasket enough to refit the cylinder head?
It replaces the head gasket only. If you also remove the cylinder, go for a complete top end gasket kit instead.
