1978 Honda CB750F · Gaskets & Mounting Hardware Buying guide

Choosing exhaust port seals and retaining hardware

Identify the sealing joint and the retaining components on the exhaust currently fitted. Port gaskets, flange clamps and the stud-and-nut set are separate repair choices; compare the existing pieces and the contents of any engine gasket set already being ordered.

Clamp quantities for the repair

The flange-clamp listing states four are used per bike and asks for the quantity required. Count the clamps actually needing replacement, and compare the retaining arrangement if a different exhaust system has been fitted.

Stud-set scope

The stud set lists the 1975–78 CB750F but gives no thread dimensions. Match the installed hardware before ordering for a changed or repaired cylinder-head arrangement; a shared model application does not identify nonstandard fittings.

Exhaust gasket questions

Do the two individually listed headpipe gaskets serve different joints?

Gaskets 17-2812 and 18-7013 both reference 18291-MM5-860. The second is explicitly described as the cylinder-head-to-headpipe gasket. Their separate listings do not establish two sealing locations; compare the offered items and choose the required gasket rather than automatically ordering both.

Should exhaust gaskets be added to overhaul gasket set 18-0441?

That overhaul set explicitly includes four exhaust headpipe gaskets. Account for those supplied seals before adding individual port gaskets for the same engine work. Separate gasket purchases remain an option for repairs that do not require the overhaul assortment.
