1979 Honda CB750K · Gaskets & Mounting Hardware Buying guide

Keep each gasket tied to the joint it seals

The featured headpipe gasket is supplied as one piece. The separate joint gasket lists OEM 18391-425-000 and 18391-MJ4-000. Distinct references and photographs help prevent ordering the wrong sealing component.

Compare with the removed gasket.View part

Use both the reference and the removed part

The exhaust port gasket listing references OEM 18291-254-000 and 18291-MM5-860. The headpipe joint gasket uses separate references. Compare the shape shown and the component removed from the connection; a matching motorcycle year does not make different exhaust seals interchangeable.

Build a hardware order from the fitted pieces

Inspect the hardware at the actual connection before adding replacement fastening parts. Note what can be reused and what needs to be replaced, then review the relevant specification and package contents. Keep that assessment separate from the number of gaskets needed for the sealing work.

Common questions

Which references apply to the exhaust port gasket?

The featured individual port gasket references OEM 18291-254-000 and 18291-MM5-860. Read its one-piece quantity and compare the old gasket with the photograph when preparing the parts order for the connection.

Is the joint gasket the same as the port gasket?

They are listed as different sealing parts with different references. The headpipe joint gasket lists 18391-425-000 and 18391-MJ4-000. Identify the connection and compare the removed component before choosing either product.

Should the gasket quantity decide my hardware quantity?

Check them separately. The gasket listing describes its package, while fastening parts have their own specifications and contents. Count the seals being replaced and assess the fitted hardware for the particular connections being serviced.

Not sure which part you need?

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