1978 Honda CB400TII Hawk II · Fuel & Intake Buying guide

Start with the condition of the twin-carb intake

These choices cover carburetor sealing, the cylinder-head intake connection and the original air cleaner. Establish what is fitted before choosing parts, particularly on a motorcycle that has been modified.

Restore sealing before fine tuning

Cracked holders and damaged sealing pieces can complicate carburetor work. Inspect the intake connections and confirm that the air cleaner is complete before making tuning decisions. Replace the affected components, then follow the Honda manual for the applicable carburetor checks.

Keep the two-carb order clear

The basic kit serves one carburetor, and each replacement holder comes with one O-ring. Make a separate quantity line for each product. Servicing both carburetors takes two basic kits; replacing both holders takes two holder-and-O-ring assemblies.

Common questions

How many rebuild kits do I need for both carburetors?

Each basic kit services one carburetor. The Hawk II has two carburetors, so order two kits when rebuilding both with this gasket, float-needle and O-ring package.

Does a replacement holder include its sealing O-ring?

Yes. Each featured holder comes with one rubber O-ring. The motorcycle uses two holders, so order two assemblies if both sides need replacement, and inspect the existing band clamps separately.

Will the stock-type filter suit a pod-filter conversion?

It is intended for the original listed air-filter arrangement. Check the installed intake system first; a motorcycle running individual filters needs parts chosen for that conversion, not automatically the stock element.

Not sure which part you need?

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