1979 Honda CB750F · Engine Covers & Seals Buying guide

Match the cover location before choosing its seal

The chrome spark-advancer cover, its rubber sealing ring and the starter-cover gasket serve separate parts of the 1979 CB750F engine. Identify the component needing replacement and compare its reference before combining a cosmetic cover purchase with sealing parts.

Assess the cover and sealing ring separately

Compare the chrome cover’s condition with the existing sealing ring before deciding which pieces the job requires. The separately offered ring provides a repair choice when the cover is retained; replacing a cover does not by itself establish the condition of every adjacent sealing part.

Keep the replacement references with the repair list

The spark-advancer cover and its ring use 30371-425-010 and 30372-425-000 respectively. Keep those references separate from the starter-cover gasket reference when ordering for more than one engine location, especially if the fitted covers have been changed.

Questions before ordering

Is the spark-advancer ring already supplied in Athena’s top-end gasket set?

Yes. Athena top-end set 18-0432 explicitly lists 18-7059 as its ignition-points-cover gasket, with the same 30372-425-000 reference as the separately offered spark-advancer ring. Check that supplied piece before adding another simply because the two listings use different names for the cover.

Which starter-cover gasket listing distinguishes the DOHC bike from the earlier CB750?

The selected 18-7070 lists the 1979–82 CB750F and reference 31282-425-300. Earlier rubber gasket 18-7011 lists 1969–78 CB750 models and reference 31282-300-020. Compare the exact reference and fitted engine, rather than choosing either part solely from the shared “CB750 starter cover gasket” name.
