ATHENA Cylinder Head Gasket for KTM EXCF 350, FREERIDE 350, SXF 350, XCF 350, XCFW 350 and HUSQVARNA FE 350 2011-2017

The ATHENA S410270001038 head gasket is designed for KTM EXCF 350, FREERIDE 350, SXF 350, XCF 350, XCFW 350 and HUSQVARNA FE 350 from 2011 to 2017. 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.
