ATHENA Intake Gasket for BETA RR 50, RIEJU MRT 50 and APRILIA MX 50, RX 50 1995-2024

The ATHENA S410130010012 intake gasket is designed for APRILIA MX 50, RX 50, BETA RR 50 and RIEJU MRT 50 from 1995 to 2024. The intake gasket seals between the intake manifold, the reed valve block or the throttle body and the engine. A leak here lets in unmetered air: the engine runs lean, the idle becomes unstable and the engine runs hot.

Specifications

When to replace it?

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.
