About the Yamaha XS400

Separate the early XS400 and Special applications from the later Seca before ordering.

Yamaha Motorcycle Logo

The XS400 name spans more than one Yamaha twin. The 1982 Seca introduced a different DOHC engine and monoshock chassis. An XS400 badge and an approximate year therefore cannot identify the engine gasket, carburetor or brake parts fitted to every version.

Use this family page to choose a model, then move to the repair. The early overhaul gasket set lists XS400 1977–1981 and XS400S 1980–1982. The separate Athena set lists XS400R 1982–1984 and later XS400 applications. Those are different engine-service products, with their own fitment lines.

Choose the correct model and applicationYamaha XS400 model and repair differences

Early XS400

Carburetor and engine service

The carburetor-kit example covers XS400 1977–1979. The early overhaul gasket set extends to 1981; that later gasket coverage does not extend the carb kit.

XS400S

Special applications

The S collection has its own brake and clutch applications. Keep XS400S in the selection rather than assuming an unsuffixed XS400 listing covers the same parts.

XS400R

Seca engine and chassis

Use the R collection for the later Seca examples, including its separate engine gasket set and front master-cylinder kit. A shared dust seal does not establish complete fork interchange.

Frame, engine and fitted componentsYamaha XS400 identification checklist

  • Record both frame and engine identity; a replacement engine can require a different gasket family.
  • Check the complete model designation and market against the correct Yamaha manual. Do not treat an S or R suffix as optional.
  • Identify the carburetor body and fuel-valve arrangement before selecting a kit or float needle.
  • Record front and rear brake type separately, then compare the actual caliper or drum and fork-seal dimensions.

Yamaha XS400 parts questions

Are all Yamaha XS400 engine gasket sets interchangeable?
No. The early overhaul set lists XS400 1977–1981 and XS400S 1980–1982, while the separate Athena set includes XS400R 1982–1984. Identify the fitted engine and check the exact product application; a shared 400 name is insufficient.
Should I choose XS400, XS400S or XS400R in the selector?
Use the complete model designation from the motorcycle and its documentation. Keep the S and R entries separate. If the bike has a replacement engine or front end, identify that assembly separately before selecting its parts.
Does the early XS400 carburetor kit cover 1980 or 1981?
The featured carburetor rebuild kit lists XS400 1977–1979. It does not establish 1980 or 1981 coverage. A gasket set with later engine applications does not extend the carb kit's fitment.
Are XS400 fork dust seals the same as oil seals?
No. Oil seals retain fork oil; dust seals protect the sealing area from contamination. Each has its own dimensions and fitment. A shared dust-seal application does not prove that the oil seals or complete forks interchange.
