1964 Honda CB77 · Fuel System Buying guide

Narrow the repair before choosing carburetor parts

Choose the individual drain fitting for a focused repair, or investigate the linked CB77 kit for a larger job. Check kit contents before ordering separate components that might overlap.

Related parts: CB77 carburetor rebuild kit

Check the kit before combining purchases

The related rebuild kit is listed for CB77 models from 1961–68, but its description does not itemize the contents. Ask what is supplied and how many carburetors the package covers before adding separate parts. Do not assume the kit contains a drain screw or any particular jet size.

Account for changes made during earlier repairs

Both the drain screw and the linked kit have an explicit CB77 application. If previous work introduced a replacement carburetor or bowl, identify that assembly when checking the order. Its parts requirements may differ, and the motorcycle year alone will not describe those changes.

Buying questions

Should I order the screw separately when buying a rebuild kit?

Check the kit contents first. The linked kit does not provide an itemized contents list, so inclusion of the drain screw is unresolved. The separate screw supplies one screw with an O-ring for an identified replacement need.

How much does one rebuild kit cover?

The kit description names the CB77 1961–68 application but does not state the number of carburetors covered or list the supplied components. Confirm package coverage and contents against your repair list before selecting a quantity.

What if the bike has replacement carburetors?

Use the fitted carburetor identification and any known bowl changes when checking parts. The CB77 application is relevant to the motorcycle, but a replacement assembly needs a match to its own components.

Not sure which part you need?

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