About the Kawasaki S3 400

Engine, ignition and fuel-tap service for Kawasaki’s 399 cc two-stroke triple.

Kawasaki Motorcycle Logo

The Kawasaki S3 400 Mach II uses a 399 cc, three-cylinder two-stroke engine. On a restoration, the installed ignition and carburetor equipment are important parts references: a converted ignition or replacement carburetor can change the service components required.

Check the installed fuel and ignition equipment

The gasket set, contact point and petcock repair kit linked below list S3 1974–1975. Some small carburetor parts are recorded specifically as S3A 1975. Keep that model suffix and each part’s year range with the assembly you are repairing.

Know your model before choosing partsKawasaki S3 400 repair checkpoints

Use the complete model, year and fitted assembly. Each product has its own application and package contents.

S3 1974–1975

The linked gasket, ignition-point and fuel-tap repair listings include these years. Compare the supplied contents with the actual job.

S3A 1975 hardware

A carburetor float-pin entry uses the more specific S3A 1975 designation. Keep that suffix when checking small carburetor components.

Other Kawasaki triples

A shared entry on one product does not prove complete S1, S2, S3, KH or H-series interchange. Chassis, fuel and ignition repairs each need their own match.

Identify your model before orderingKawasaki S3 400 identification checklist

Use the identification on your machine and the component being repaired.

  1. Read the complete frame model and year; record engine markings separately if the engine may have been changed.
  2. Identify the carburetors and whether the original contact-point ignition is still installed.
  3. Photograph the fuel tap and inspect the original repair pieces before selecting a kit.

Choose a repair below, then confirm the product’s model and year. These examples do not change with the year filter.

Restoring or customizing your Kawasaki S3 400?

When changing an S3’s bars or mirrors, measure the mounts and check throttle-cable routing. Retain full control movement and clearance at both steering stops.

Universal parts require measurement and are not a confirmed Kawasaki S3 400 fit.

Kawasaki S3 parts questions

Which S3 years do the featured repair parts cover?
The linked engine gasket set, contact point and petcock repair kit list S3 1974–1975. Other products can have different model labels or years, so check the individual application rather than extending that range to the whole collection.
Does an S3 engine gasket set include crankshaft oil seals?
That is not established by the set name. Compare the listed contents with the engine diagram and the seals required for your repair. Gaskets and rotating-shaft seals are separate types of sealing parts.
Is the S3 petcock listing a complete replacement tap?
The featured item is a petcock repair kit. Check the product contents and compare them with the fitted tap; do not order it on the assumption that a complete fuel-tap body is included.
Will S3 contact points work with an electronic ignition conversion?
Do not select contact points by the motorcycle year if the ignition has been converted. Identify the installed ignition system and follow its component requirements.
