ATHENA Intake Gasket for YAMAHA YZ 250 and FANTIC XX 250 1999-2026

ATHENA offers this intake gasket for YAMAHA YZ 250 and FANTIC XX 250 1999-2026. Fitted between the cylinder and the intake manifold or reed valve, it stops unwanted air getting in: an air leak leans out the mixture and makes the engine run hot.

Why replace this gasket every time it is removed?

The benefits:

• A new gasket guarantees a perfectly sealed joint.
• Material designed to withstand heat, oil and coolant.
• An inexpensive part that saves doing the job twice.

Why choose ATHENA?

Athena, founded in 1973 by Giovanni Mancassola near Vicenza and based in Alonte (Italy), designs gaskets, pistons and cylinder kits; it supplies original equipment to manufacturers such as KTM, Ducati, Fantic and Triumph.

When should you replace the intake gasket on your YAMAHA YZ 250?

An idle that rises or hunts, flat spots under acceleration or an engine running hot can all come from an intake air leak. Replace the gasket every time the intake manifold or reed valve comes off.
