Parts and fitment guide for your 1978 CB750A

Use the 1978 Honda CB750A Hondamatic application for carburetor, intake and oil-system repairs. Shared filter coverage with the CB750K or CB750F does not establish interchangeability of the surrounding assemblies.

Browse by repair

Engine parts — filters, seals and engine components.
Fuel-system parts — carburetors, air filters and fuel delivery.
Electrical parts — ignition, switches and charging parts.
Brake parts — brake components; check Hondamatic-specific applications.
Suspension & wheels — fork, wheel and suspension components.
Exhaust parts — exhaust components, gaskets and hardware.

Selected parts for the 1978 CB750A

Check each listing for model fitment, dimensions and included quantities before ordering.

Stock air filter — for the stock-airbox application; check modified intakes separately.
Oil filter — paper element; seals and hardware are listed separately.
Oil-pump gasket — Hondamatic-specific gasket for the left crankcase-to-oil-pump joint.

Identify your CB750A (1978)

Use the complete model and original market when matching the motorcycle to reference information.

Frame and engine — record both complete stampings, including every prefix and suffix.

The registration year alone does not identify the carburetors or other assemblies now fitted.

Use the linked chart as an identification aid, not as a verified factory serial range.

View the CB750 reference chart

For help locating identifiers, see our Honda CB model identification guide.

Match the float and pump components

Carb kit 48-1997 and float-with-pin 20-6509 both list the 1978 CB750A, but the rebuild kit does not list the float body among its contents. Identify whether the repair needs the float, inlet needle or both. Pump diaphragm 20-9040 also lists the Hondamatic; the description’s 89mm pin condition applies to its CB650 applications, not a stated CB750A measurement.
