1977 Honda CB750F — Joints et fixations

Remounting the exhaust on a 1977 Honda CB750F calls on five listings. There are two port gaskets sold one at a time, a collector gasket for 1976-77 machines, a flange clamp built to the stock pattern and a kit of eight studs with eight nuts.

1977 Honda CB750F · Exhaust gaskets & hardware Buying guide

Match the gasket to the connection

Identify the exhaust connection and required replacement reference before choosing a gasket. Select the clamp and stud hardware separately for the exhaust fitted, rather than treating a model tag as a complete parts list.

Flange clamp reference

Clamp 07-4622 replaces 18231-392-000 and is sold individually. Its application lists the 1975–78 CB750F, 1976–78 CB750A and 1977–78 CB750K. Match the reference and fitted exhaust hardware before ordering.

Stud and flange-nut set

Set 73-1141 includes eight exhaust studs and eight flange nuts and lists the 1975–78 CB750F and 1977–78 CB750K. Confirm the hardware required by the fitted assembly; the package contents do not establish the arrangement of an aftermarket exhaust.

Exhaust hardware questions

Do the 254 and MM5 references identify two separate port-gasket purchases?

The two listings overlap: 17-2812 cross-references both 18291-254-000 and 18291-MM5-860, and 18-7013 lists 18291-MM5-860. Both are individual cylinder-head-to-headpipe gaskets. Choose against the replacement reference required by the fitted assembly, rather than assuming the two listing names identify separate sealing positions.

Can either port gasket substitute for the collector gasket?

The listed joints are different. Port gaskets 17-2812 and 18-7013 seal where a headpipe meets the cylinder head. Gasket 17-4529 is instead listed for the headpipe-to-collector connection on the 1976–77 CB750F. Match that connection on the fitted exhaust before ordering.
