1982 Honda CB750K · Exhaust Gaskets & Hardware Buying guide

Keep gasket quantities separate from unspecified stud-pack contents

The port gasket is expressly sold each. The stud description provides an 8 x 55mm size and reference 90035-425-000, but does not state a pack quantity. Use the documented gasket unit and confirm the hardware contents separately.

Order seals by joint rather than appearance

The cylinder-head port gasket and downstream headpipe joint gasket have different references. Compare the exhaust diagram and existing connection before ordering either. This is especially useful when aftermarket pipes have replaced only part of the original system and the remaining joints are mixed.

Resolve the separate stud-kit count before combining purchases

The separate 73-1140 stud-and-nut kit calls itself an eight-piece kit, yet also lists eight studs and eight flange nuts. Confirm that conflicting contents description before choosing it instead of the standalone stud listing. Neither hardware listing supplies an exhaust gasket in its stated contents.

Common questions

Should I add port gaskets when I already have the Athena top-end set?

Athena top-end set 18-0432 lists four exhaust headpipe gaskets under replacement reference 18291-MM5-860. The individual port gasket lists that same replacement reference. Check the gasket set already purchased before adding another complete quantity of port seals.

Can the stud-and-nut kit’s eight-piece label set my order quantity?

Not reliably: its description also says eight studs plus eight flange nuts. Ask us to confirm the supplied quantities before relying on that total-piece label. Do not use it to infer the package quantity of the separately listed stud either.

Can I confirm the stud’s pitch and supplied quantity from 8 x 55mm?

No. That is the size notation in the current stud description, which also gives reference 90035-425-000. It does not specify thread pitch or package quantity. Confirm those details when needed, rather than treating the size as a complete hardware specification.
