1977 Honda CB750K · Exhaust Gaskets & Hardware Buying guide

Count the pieces for the mounting repair you need

The product quantities differ: a gasket listing is one piece, a clamp listing is one clamp, and the stud set contains eight studs plus eight flange nuts. Match the package to the actual work without duplicating parts.

Keep gaskets, clamps and studs as separate components

The port gasket seals its listed connection, the flange clamp is a separate fitting, and the stud package supplies studs with flange nuts. None of those descriptions makes one item a substitute for the others. Compare the parts removed before deciding which components must be replaced.

Compare the fitted system before ordering a full quantity

The clamp listing gives four used per bike for its original-style application. A motorcycle with different pipes or flanges needs a direct comparison with the exhaust instructions. Use the appropriate service information for damaged studs and installation rather than choosing repair methods from a hardware quantity alone.

Choosing parts for your 1977 CB750K

How many pieces are in the stud kit?

The described package contains eight exhaust studs and eight flange nuts. It does not list port gaskets or flange clamps. Inspect those components separately and order the needed quantities after checking the actual exhaust arrangement.

Does one flange clamp purchase supply all four?

No. The clamp is sold individually, and its listing states four used per bike for the specified application. Order the quantity required. If the exhaust has been changed, compare its fitting requirements before assuming that count still applies.

Is each exhaust port gasket listing a multi-pack?

The featured gasket listing is explicitly one piece, sold each. Count the gasket positions involved in your repair and order that quantity. A stud set or other mounting part does not automatically supply the port gaskets.

Not sure which part you need?

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