ATHENA Exhaust Gasket O-ring Ø36.1 x 3.53 mm for KAWASAKI KDX 80, KX 80, KX 100 1981-1997

The ATHENA M753504143094 exhaust gasket is designed for KAWASAKI KDX 80, KX 80, KX 100 from 1981 to 1997. The exhaust gasket seals between the cylinder or cylinder head outlet and the exhaust system. A leak at this point costs power, makes the engine noisy and covers the frame in black marks.

Fitting tips

1. Clean the gasket seat on both the engine side and the exhaust side.
2. Fit the O-ring in its groove without twisting it; a little high-temperature grease makes it easier to push the parts together.
3. Offer up the exhaust without forcing it, fit all the fasteners, then tighten progressively.
4. Warm the engine up, let it cool down and check the tightness again.

Frequently asked questions

Can I reuse the old gasket?
No: it crushes and deforms as it heats up. A new gasket costs little and prevents a leak.
