1982 Honda CB450SC Nighthawk Carburetor Kit & Seal Selection

The service kit listed for the 1982 Honda CB450SC Nighthawk covers one carburetor. The separate bowl gasket and float needle offer more focused ordering choices when the fitted parts need attention. Confirm the carburetor identity first, especially if a previous owner replaced the original assembly.

1982 Honda CB450SC Nighthawk · Carb Rebuild & Jetting Buying guide

Choose the service scope after matching the carburetor

Two kits are specified to service the complete 1982 carburetor system. The bowl gasket is sold individually, and the float needle listing supplies a needle without its seat. An exact kit inventory and jet sizes are not published here, so do not assume every original component is included.

Do not infer the kit’s exact jetting from its name

The listing identifies the year and one-carburetor coverage but does not enumerate all kit pieces or jet sizes. Compare the original jets, needles, gaskets and O-rings as its FAQ directs. Confirm any specific required piece before relying on the kit to supply it.

Keep the float valve seat in the inspection plan

The separate needle source explicitly excludes the seat. Inspect the seat condition along with float movement and the correct model-specific float-height procedure. A needle purchase should follow that assessment, rather than assume the needle replaces every part of the shutoff assembly.

Common questions

How many kits are specified to service both original 1982 carburetors?

One kit services one carburetor, and the listing specifies two kits for the complete 1982 CB450SC system. First confirm the fitted carburetors match that application; the listing excludes the later 1983–1986 CB450SC kit application.

Can I confirm the supplied jet sizes or complete contents from this listing?

The current listing does not publish jet sizes or an exhaustive contents list. Its FAQ directs comparison with the original metering and sealing parts. Confirm the specific pieces needed before ordering, rather than infer their inclusion from the kit name.

Does the separate float needle include a new seat?

No. The 16155-413-751 listing supplies one float needle without the seat. Inspect the existing seat and float movement before ordering. A worn or damaged seat needs separate assessment because it is not renewed by the needle-only package.

Not sure which part you need?

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