Identify the CB100K code and match each part’s year range
Check the full model marking: The CB100 K-series includes K0–K3. K3 appears in 1973 catalogs and in a Thailand 1974 catalog; match the stamped code and year to each product’s application.
Keep part-year ranges separate: The carburetor kit and overhaul gasket set cover CB100K 1970–1972; front brake shoes cover 1970–1973. One carburetor kit services one carburetor.
Compare the fitted parts: If the carburetor or engine has been replaced or modified, check its markings and gasket/jet layout before ordering. For the broader family page, see Honda CB100 parts.

Building a custom CB100K?
For a changed cockpit, compare universal handlebars and grips with mirrors and adaptors. Check clamp diameter, mirror mounts, cable reach and steering clearance on your CB100K; some universal parts may need modification.
