ATHENA Intake Gasket for KTM SX 50, SX 65, XC 65, HUSQVARNA TC 65 and GAS GAS MC 50, MC 65 2009-2026

On KTM SX 50, SX 65, XC 65, GAS GAS MC 50, MC 65 and HUSQVARNA TC 65 from 2009 to 2026, the ATHENA S410270010007 intake gasket fits in place of the original part. On the intake side, the slightest sealing fault upsets the air-fuel mixture. This gasket makes sure that all the air drawn in goes through the carburettor or the fuel injection.

Specifications

• Brand: ATHENA
• Manufacturer part number: S410270010007
• EAN code: 8051757107421

When to replace it?

• Unstable idle or idle that creeps up on its own, hanging revs.
• Engine running hot or pinking: mixture too lean.
• Gasket crushed or split on removal.

Every time the intake manifold or reed valve block is removed, and as soon as an air leak is suspected.

Fitting tips

1. Clean the gasket faces without scratching them.
2. Fit the gasket dry and properly centred.
3. Tighten the screws in a criss-cross pattern, gradually, to the manufacturer's torque.
4. Take the opportunity to check the reed petals: a chipped or split tip must be replaced straight away.

Frequently asked questions

How do I find an air leak?
With the engine idling, spray a little brake cleaner around the intake: if the revs change, air is getting in at that spot.
