ATHENA Cylinder Head Gasket for KTM ENDURO 690 2008-2013

On KTM ENDURO 690 from 2008 to 2013, the ATHENA S410270001031 head gasket fits in place of the original part. Between the cylinder head and the cylinder, the head gasket contains the pressure of every explosion. Once tightened, it takes the shape of the parts: on reassembly you need a new gasket to keep full compression.

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.
