1967 Honda CB450K Carburetor Kits & Pilot Jet Choices

For a 1967 CB450K carburetor order, compare the premium kit’s stated contents with the parts already inside your carburetor. The separate #35 pilot offers a single metering component. Choosing a broader service kit does not settle which jet calibration your setup requires.

1967 Honda CB450K · Carb Rebuild & Jetting Buying guide

Read the metering parts and package scope together

The kit contains a #125 main jet, #40 pilot and D8 needle alongside gaskets and float-valve parts. The separately sold pilot is #35. Check both the jet pattern and the intended size before selecting either approach.

Separate the main, pilot and needle information

The kit’s three metering specifications refer to different components: #125 main, #40 pilot and D8 needle. Compare each with the part it would replace. Avoid treating a single matching number or the CB450K application label as proof that every included metering component suits an altered carburetor.

Account for parts outside the kit

The contents list includes a float needle and seat but does not list a replacement float. It also does not describe a full intake or carburetor mounting assembly. Inspect the parts being retained before ordering so the choice of a service kit does not leave an unrelated damaged component unresolved.

CB450K ordering questions

Is the #35 pilot an identical spare for the kit’s pilot?

The kit specifies a #40 pilot; the separate listing specifies #35. Those are different stated sizes. Check the installed jet pattern and the intended calibration rather than buying the separate part as though it duplicated the kit’s pilot.

Does the D8 marking identify every needle that will work?

D8 is the needle listed in this kit. The product does not establish every possible interchange or calibration for other carburetors. Compare the installed needle and carburetor details before assuming the supplied needle should replace an undocumented earlier modification.

How should I calculate kit quantity for the service?

Use the number of carburetors you intend to rebuild: the listing states one carburetor per premium kit. A photograph of multiple small parts does not make it a motorcycle set. The separate pilot jet is explicitly sold each.

Not sure which part you need?

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