PROX Ignition Cover Gasket for YAMAHA YZ 125 and FANTIC XE 125, XX 125 2005-2026

On FANTIC XE 125, XX 125 and YAMAHA YZ 125 from 2005 to 2026, the PROX 19.G92205 ignition cover gasket fits in place of the original part. On the left-hand side of the engine, the ignition cover protects the flywheel and the stator. Its gasket keeps it sealed: a crushed or torn gasket lets oil, water or dust through.

Specifications

• Brand: PROX
• Manufacturer part number: 19.G92205
• Weight: 10 g
• Engine: 2-stroke

When to replace it?

• Oil seeping around the edge of the ignition cover.
• Water or mud inside the cover after washing.
• Gasket torn or stuck on removal.

Every time the ignition cover comes off: stator check, replacement of an ignition-side crankshaft oil seal or bottom end rebuild.

Fitting tips

1. Clean both gasket faces without scratching them.
2. Fit the gasket dry; a dab of grease can hold it in place during reassembly.
3. Tighten the screws in a criss-cross pattern, without forcing, to the manufacturer's torque.
4. On an engine where the ignition runs in oil, top up the oil level after reassembly.

Frequently asked questions

Can I reuse the old gasket?
No: a paper or fibre gasket tears or stays crushed when removed. If you're opening several covers, a complete engine gasket kit often works out cheaper.
