1972 Honda CB500K Intake Holders & Airbox Boots

The 1972 CB500K intake has separate engine-side holder and carburetor-to-airbox boot listings. Choose the joint being repaired before ordering either four-piece set. Their clamp counts and diameters differ, and the stainless rack-support bracket serves a separate purpose when the stock airbox is not retained.

1972 Honda CB500K · Intake Rubber & Rack Support Buying guide

Identify which side of the carburetor needs new rubber

Holders replace the engine-side connection; boots join the carburetors to the compatible airbox. Each set supplies four rubber pieces. Match the correct clamp specification, then consider rack support separately if the motorcycle has the listed custom intake arrangement.

Check clamp counts against the joint being renewed

The holder source calls for eight 41–44mm clamps for the complete set. The boot source specifies four 45–47mm clamps when originals need replacement. Examine the existing hardware and match the respective specification; the fact that both rubber sets contain four pieces does not make their clamps identical.

Keep a support bracket separate from sealing components

The stainless bracket is listed for rack support with pods or a no-airbox setup. It does not supply rubber holders, boots or band clamps. Confirm which intake arrangement will remain fitted before adding it, rather than assuming the bracket replaces the sealing function of either rubber set.

Common questions

Which rubber set and clamps match the engine-side joints?

The holder set references 16211-323-000 and supplies four holders. Clamps are separate, with eight 41–44 mm clamps specified when replacements are needed. Check the retained engine-side joints and existing hardware before applying the different airbox-boot clamp specification.

How many airbox boots come in one set?

Four boots are supplied for the listed CB500K four-carb arrangement. If clamps need replacing, the source calls for four 45–47 mm clamps. Confirm the original airbox is retained and compare its connecting joints before ordering the rubber package.

How should I account for rack support after the airbox is removed?

The stainless bracket is listed to support the compatible four-carb rack in a pod or no-airbox setup. One bracket supports one rack. Check that support requirement alongside the intake seals; retaining or replacing airbox boots is a different fitment decision.
