1968 Honda CB450K Carburetor Kit Choices & Jetting

Two carburetor kit listings are available for your 1968 CB450K, with different information to check before ordering. One specifies 14H and 14L carb models; the premium option names its supplied parts. Match the fitted carburetor before choosing either kit or a separate metering component.

1968 Honda CB450K · Carb Rebuild & Jetting Buying guide

Compare the model-specific kit with the detailed contents list

The 14H / 14L kit requires carburetor identification. The premium kit lists #125 main, #40 pilot and D8 needle among its contents. A needle-and-seat set and separate #35 pilot provide narrower component choices.

A shared model application does not resolve kit interchange

One kit identifies the carb models it is intended to service, while the premium listing names its components. Use both kinds of evidence to check the repair. If your fitted carburetor differs from the stated model or parts, confirm compatibility rather than making an unsupported substitution between the two listings.

Order the repair scope and quantity you need

Both kits state one carburetor serviced per kit. The separate float valve supplies a needle and seat, while the pilot listing supplies a #35 metering jet. Check the kit contents before adding individual parts to avoid assuming a missing component or buying a duplicate repair without comparing the actual pieces.

Practical CB450K buying questions

Does the 14H / 14L kit have the same jets as the premium kit?

Its description does not give a detailed contents list or state those jet sizes. The premium kit specifically lists #125 main and #40 pilot. Confirm the contents needed for your carburetor; do not transfer one kit’s specifications to the other.

Does either kit cover both carburetors in one purchase?

Both kit descriptions state one carburetor per kit. Calculate the order from the carburetors being rebuilt, after identifying their models and needed parts. The separate needle-and-seat set or pilot listing does not change the kit’s stated service quantity.

Is the separate #35 pilot meant to replace the premium kit’s #40 by default?

No default substitution is established. The separate jet requires the correct 99124-286-style pattern and a deliberate #35 size choice. Compare the installed carburetor and intended calibration before replacing the kit’s pilot or ordering another size.
