1981 Honda CB400TB Fuel-System Parts

The 1981 Hawk’s carburetors depend on sound intake connections, the correct air-cleaner arrangement and a properly sealed fuel tank. Begin with the fitted equipment and the source of the fault, then choose the service part rather than replacing unrelated fuel-system components together.

1981 Honda CB400TB · Fuel & Intake Buying guide

Check the whole fuel path before buying carburetor parts

The featured air filter, engine-side carb holder and fuel-cap seal address three different service points. Confirm the original equipment remains fitted and keep carburetor sealing, fuel delivery and tank mounting decisions separate.

Parts to consider

Check the intake before changing calibration

An aged holder or poorly seated air filter can complicate a running problem. Inspect those connections before deciding that different jets are needed. Keep the original air-cleaner arrangement and any exhaust or carburetor changes in view when discussing diagnosis with the person performing the repair.

Use the tank repair to identify the fitting

The cap seal, petcock connection and front mounting cushions serve separate points on the tank. Compare the actual cap and threaded connection if the tank has been changed. A model-specific replacement is useful only when the installed tank retains the matching fitting.

Buying questions

Can these stock intake parts be used with pod filters?

The featured air-filter element is for the original air-cleaner arrangement. Identify any conversion before ordering; pod filters and altered carburetor mounting may require a different parts selection and separate calibration assessment.

How many carb holders does the bike use?

The original arrangement uses two engine-side holders. Each featured purchase includes one holder and its O-ring, so order two if both are being renewed.

Does the 1981 cap use the same seal as every earlier Hawk?

Use the specific 1981 cap application rather than a general Hawk assumption. The featured seal references 17632-176-771; compare the fitted cap carefully if the tank or cap has been replaced.

Not sure which part you need?

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