1973 Honda CB500K Exhaust Fasteners & Sealing Parts

For exhaust mounting work on a 1973 Honda CB500K, inventory the old fasteners before choosing a package. The stud set supplies defined hardware quantities. Port gaskets and the chrome header clamp remain separate products, allowing the order to match what is actually missing or worn.

1973 Honda CB500K · Gaskets & Mounting Hardware Buying guide

Build a hardware list before opening the exhaust

The set contains studs, washers and nuts rather than every item around the headpipe. Review the clamp, port seal and any original-style muffler connector individually so package contents are not confused with the repair’s complete needs.

Parts to consider

1971-78 Honda CB550F / CB550K / CB500K Exhaust Stud Set Eight-stud exhaust hardware setListed package contains eight exhaust studs, eight washers and eight nuts for the CB500K application.

Read the stud package as a parts list

Eight studs, eight washers and eight nuts are explicitly included. That is the hardware purchase you can plan around, rather than a combined clamp-and-gasket kit. Look over the remaining pieces at the exhaust ports and select any separate replacements required for the fitted assembly.

Different seals belong at different connections

The metal port gasket is listed under Honda 18291-216-000 / 18291-MN5-650. The genuine rubber tube uses 18473-323-000 at a specified original-style muffler connection. Keep those applications separate, and identify the connector’s actual location before deciding how many rubber tubes to order.

Exhaust Fasteners & Sealing Parts questions

Which dimension identifies the clamp’s mounting pattern?

The chrome 14-fin clamp has mounting holes 55mm apart center to center. Compare that spacing with the fitted flange hardware, especially for custom headers. The figure is a mounting measurement, not a stated exhaust-pipe diameter.

Do I need the ten-pack if I am sealing only one exhaust port?

The individual listing supplies one gasket, while the pack supplies ten with the same Honda replacement references. Order for the ports being serviced and any spares you want; the pack does not specify a different gasket application.

What should I inspect before ordering a connector rubber for a joint leak?

Inspect the existing rubber, mating pipes and clamps. Badly corroded or distorted metal can prevent sealing even with a new tube. Confirm the joint position and 18473-323-000 reference before choosing the rubber.
