About the Honda ATC90
Engine, carburetor and wheel-hub service for Honda’s early ATC90 three-wheeler.
The ATC90 belongs to Honda’s early three-wheeler range. Its engine, carburetor and wheel hubs each need their own restoration parts: an engine gasket seals a joint, the carburetor float controls the fuel level through its valve, and a hub seal protects the wheel assembly. Identify any replacement engine or hubs before choosing those components.
Separate engine sealing from wheel-hub service
An engine gasket set can cover more years than a hub service kit. Here, the linked gasket set lists 1971–1978 and the wheel-seal kit lists 1976–1978. Match the assembly being opened, and check the package contents rather than assuming every oil seal accompanies an engine gasket set.

The linked gasket set and float list this range. Compare the engine joints and the fitted carburetor before ordering.
1976–1978 wheel-seal example
The featured kit has narrower coverage. A hub conversion or earlier ATC90 needs separate seal identification.
