1979 Honda CB750K · Carb Floats & Other Carb Components Buying guide

Match parts to the carburetor assembly being serviced

Float, accelerator-pump and air-cutoff parts have separate references and contents. Identify which assembly needs work before selecting seals or a replacement component.

Keep the tube seals identified

The twelve-piece O-ring package is for fuel connector and accelerator tubes. It is a different service item from the four-pack of float-bowl drain screw O-rings.

Use the 1979 air-cutoff application

The featured air-cutoff valve is listed for the 1979 carburetors. If a later carburetor bank has been fitted, identify that bank before choosing the diaphragm and spring references.

Common questions

Does the replacement float include its pivot pin?

Yes. The float, reference 16013-679-005, is supplied with a pin.

Is the accelerator-pump bellows included with the diaphragm?

Yes. The package contains one diaphragm with its rod and one bellows rubber.

Should I order drain O-rings or replacement screws?

Choose the four-pack for seals alone. The separate stock-type drain screw is sold each and includes an O-ring, so you do not need a second seal for that new screw.

Not sure which part you need?

Send your model and year, plus photos of your existing part and any changes to the original setup.
