Installation Notes

Ensure the engine is off, cool, and disconnected from the power source.
Remove the engine cover or cowling to access the exhaust components.
Carefully unbolt and remove the exhaust cover plate.
Remove the old gasket completely, taking care to scrape away any stuck-on residue from both mating surfaces.
Thoroughly clean the surfaces of the exhaust cover and the engine block.
Position the new gasket, aligning it carefully with the bolt holes.
Re-install the exhaust cover and tighten the bolts in a crisscross pattern to the manufacturer's specified torque to ensure even pressure.
Reconnect the power, start the engine, and check for any exhaust or water leaks around the cover.

Troubleshooting & FAQ

Will this gasket fit my Suzuki DT35?

Yes, based on cross-reference data from multiple sources, this gasket is compatible with Suzuki DT35 2-stroke models from approximately 1984–1994.

How do I know if my old exhaust cover gasket is failing?

Common signs of a bad gasket include visible water or exhaust leaks around the seam of the exhaust cover, engine overheating, loss of performance, or a noticeable change in the engine's sound.

Should I use sealant with this gasket?

This gasket is designed to be installed dry. Applying sealant is generally not necessary or recommended unless explicitly specified by your engine's service manual. Always clean mating surfaces thoroughly before installation.

What is the difference between part numbers 14151-94411, 14151-94412, and 14151-94400-H17?

These numbers often represent revisions or supersessions from the original manufacturer. This aftermarket gasket is designed to serve as a direct cross-reference for all listed part numbers, ensuring equivalent fit and function.

What are the signs of an improper installation?

If the gasket is not installed correctly, you may immediately notice exhaust or water leaks around the cover once the engine is running. This can lead to poor engine performance and potential overheating. Ensure bolts are torqued to spec.

How often should this gasket be replaced?

Replace this gasket whenever the exhaust cover is removed for service. It is a single-use component and should not be reused, as it crushes to create a seal.
