1979 Honda CB650 · Exhaust Seals & Studs Buying guide

Identify the gasket location and the fitted flange

The single port gasket, port-gasket ten-pack and separate headpipe joint seal have different buying roles. Choose the seal for the joint being serviced, then check the stud set against the exhaust flange actually fitted.

Keep the two gasket reference families separate

The single port gasket and ten-pack both list 18212-634-000, 18291-236-000 and 18291-MN4-920. The linked joint gasket instead lists 18391-425-000 and 18391-MJ4-000, with the 1979 CB650 explicitly included in that product’s applications.

Order from the stated hardware inventory

Stud set 73-1139 contains eight studs and eight flange nuts. Compare that written inventory with the parts needed for the job and confirm any additional component separately; the package description is not a complete exhaust-repair parts list.

Buying questions

Will the stud set suit an aftermarket exhaust flange?

The stud listing calls for checking the spacing and flange thickness on a non-stock exhaust. It gives no stud thread dimensions or length, so obtain those specifications and compare the fitted flange before ordering where the original arrangement has changed.

Can I confirm the headpipe joint gasket for a replacement exhaust by its Honda application?

The listed application identifies the motorcycle, but the joint-gasket record gives no dimensions for comparison with an aftermarket pipe joint. Identify the exhaust system and obtain its required gasket specification before treating the 18391-425-000 / 18391-MJ4-000 replacement as a match.

Can I reuse a port gasket after removing the headpipe?

Honda’s Common Service Manual calls for a new exhaust-pipe gasket whenever the pipe is removed from the engine. Include a replacement for each opened port connection and use the model-specific manual for assembly and tightening.
