1971 Honda CB500K Carb Holders & Airbox Boots

The 1971 CB500K intake rubber listings separate engine-side carb holders from carburetor-to-airbox boots. Both are four-piece sets, but the required clamps differ. A stainless support bracket is another option for the listed custom intake setups; it does not replace either rubber set.

1971 Honda CB500K · Carb Holders & Airbox Boots Buying guide

Choose the rubber set for the joint being serviced

Match the cylinder-head side or airbox side before ordering. The holders call for eight 41–44mm clamps, while the airbox boots call for four 45–47mm clamps when replacement clamps are needed. Confirm which existing parts remain usable.

The two clamp specifications are different

The holder source specifies eight 41–44mm band clamps for a complete installation. The airbox-boot source specifies four 45–47mm clamps when replacements are needed. These clamp references explain ordering requirements; they do not mean clamps come with either rubber set or are available in this model category.

Support and sealing are separate jobs

The bracket is listed to support the carburetor rack when using pods or a no-airbox setup. It is not an intake holder, airbox boot or clamp. Check the layout and installed support before choosing it, and match any rubber replacements to the joints retained on the motorcycle.

Common questions

Do the four carb holders include band clamps?

The four-holder set references 16211-323-000, with clamps explicitly separate. A complete installation uses eight 41–44 mm clamps when replacements are needed. Inspect the existing clamps before ordering additional hardware; the airbox boot side uses a different size and quantity.

Which clamps are specified for the retained airbox boots?

The four-boot package calls for four 45–47 mm replacement clamps, one per boot when the originals need replacement. Engine-side holders instead specify eight 41–44 mm clamps. Match the actual joint before choosing by clamp diameter or package count.

When is the stainless rack-support bracket relevant to the order?

The bracket supports the compatible four-carb rack when stock airbox support is removed for pods or the listed custom setup. One bracket services the rack. Confirm the fitted intake arrangement before adding support alongside separately chosen holders, boots or filters.
