1970 Honda CB450K · Fuel System Buying guide

Identify the assembly, then choose the repair scope

Carb kits, holders and tank parts use different selection checks. The 14H / 14L kit names specific carburetors; the holder gives an explicit one-piece purchase quantity. Cap choices also differ in whether latch hardware is listed as supplied.

Parts to consider

1968-71 Honda CB450K / CL450K Carb Rebuild Kit

Service kit for 14H and 14L carburetorsKit listed for carburetor models 14H and 14L, with one carburetor rebuilt per kit. Read the model number on the installed carburetor. Individual jet sizes and detailed kit contents are not given in this description.View part

Honda CB Carb Holder ~ Replaces 16211-283-000

Holder with gasket for one positionHolder referencing Honda 16211-283-000. One holder and gasket are supplied, with two holders stated per bike. Buy two for both positions and assess the separate band-clamp requirement before completing the order.View part

Honda CB Fuel Petcock ~ Replaces 16950-292-000

M16 × 1.5 replacement fuel tapPetcock referencing Honda 16950-292-000. Its M16 × 1.5 thread must be checked against the tank being used. A model application does not identify the outlet on a tank changed during previous work.View part

Keep tank hardware quantities separate

Front cushions are sold each, with two stated per bike. Emblem clamp nuts are also sold individually, but their required quantity depends on the emblem attachments being serviced. Neither product’s quantity describes the other; inspect each mounting point before turning a restoration list into an order.

Plan carburetor tools and metering from the fitted setup

The universal two-gauge synchronizer needs accessible compatible vacuum connections; its 5mm-threaded adapters do not prove that the fitted carburetors have suitable ports. A pod filter may require tuning changes, but the premium kit’s supplied jets and the separate #35 pilot do not determine those changes by themselves.

Practical parts selection questions

What is the first check when the carburetors may have been changed?

Establish the model of each installed carburetor. The 14H / 14L kit is expressly restricted to those carburetors, and the premium kit’s listed parts still need comparison with the actual assembly. Motorcycle year alone cannot identify a replacement carburetor.

Does one holder purchase cover both carburetors?

The listing supplies one holder with a gasket and states two used per motorcycle. Order two for both positions. Inspect the band clamps separately because the required clamp is identified as a separate product.

Should the tank and carburetor order include the same number of every small part?

Use each description’s supplied quantity and the number of positions being repaired. Kits service one carburetor each, front cushions are sold each, and emblem nuts are individually sold. A common motorcycle application does not make those repair counts identical.

Not sure which part you need?

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