1981 Honda CB750F · Carb Floats & Service Parts Carburetor service-parts guide

Match the repair to the carburetor component

A float-bowl repair, an accelerator-pump repair and a rack-seal replacement need different parts. Use the component location and carburetor identity to narrow the purchase before comparing packages. The selections below include individual components, seal sets and external hardware.

Parts to consider

1979-83 Honda CB900 / CB750 Carb Pump Diaphragm ~ Replaces 16021-679-005

Accelerator-pump diaphragmKit 20-9042 is listed for the 1979–82 CB750F Keihin accelerator-pump assembly. Match the pump component before choosing a diaphragm product.View part

Honda CB Carb Float ~ Replaces 16013-413-851

Carburetor float with pinThe selected float is supplied individually with its pin. The supplier lists four for the motorcycle; order the quantity needed for the repair.View part

Honda CB Carb Fuel Connector Tube and Accelerator Tube O-Rings

Connector-tube O-ring setSet 73-0831 supplies twelve O-rings for fuel connector and accelerator tubes, rather than the float-bowl drain screws.View part

Choose seals by their location

The twelve-piece felt set 33-0044 serves compatible constant-vacuum throttle and choke shafts. Drain-screw set 48-0792 supplies four O-rings only, with no drain screws. Neither set replaces the connector-tube O-ring package.

Keep the hardware order separate

Bolt-and-washer kit 73-1044 has 43 total pieces and is listed for all four carburetors. It excludes gaskets, fuel seals, jets and internal metering parts; add those only as the repair requires.

Common questions

Does the accelerator-pump kit also cover the air cut-off valve?

These are separate repair packages. Accelerator-pump kit 20-9042 supplies a diaphragm with rod and a bellows rubber, cross-referenced to 16021-679-005. Air cut-off kit 20-4020 instead supplies a diaphragm, spring and one O-ring, with references 16048-429-771 and 16048-425-771. Identify the assembly being serviced before ordering.

Which offered float is listed for the 1981 CB750F?

Float 20-6507, cross-referenced to 16013-413-851, lists the CB750F for 1980–82. The similarly named 20-6506 uses reference 16013-679-005 and lists the 1979 CB750F. Use the listing and the fitted carburetor's identity together, particularly if the rack has been changed.
