1980 Honda CB750K DOHC Engine Cover Parts

Spark-advancer cover repairs on the 1980 Honda CB750K have separate cover, sealing and screw listings. The screw page includes a specific 1980 size check. Compare the old screws and cover arrangement before ordering, and check the starter-cover gasket separately for that repair.

Check the cover, its seal and the 1980 screw size

The chrome spark-advancer cover excludes its gasket, which is a separate rubber O-ring listing. Its screw set specifies three 6 x 25 screws and asks 1980 owners to confirm the old screw size.

Read the 1980 hardware note before choosing screws

The screw listing says 1980 motorcycles may use 6 x 25 or 6 x 26 screws. This package is the 6 x 25 choice. Compare the screws removed from your engine before ordering; the general model tag does not override that specific size condition.

Order the cover and its seal deliberately

The chrome spark-advancer cover and its rubber O-ring are separate products. Inspect the existing seal and compare the listed reference before adding it. The starter motor cover gasket serves another cover and has its own reference, so keep those sealing items distinct when planning the repair.

Common questions

Does the chrome cover include a gasket?

No. Its description states that a new gasket is sold separately. The matching category contains a rubber O-ring listing against reference 30372-425-000. Compare the installed sealing arrangement and order that item if the repair needs it.

Will the listed screw set suit every 1980 CB750K?

The listing requires a size check for 1980 applications because it describes 6 x 25 or 6 x 26 screws on those bikes. The featured set is three 6 x 25 screws; confirm the removed hardware before ordering.

Is the starter-cover gasket the spark-advancer cover seal?

No. The starter motor cover gasket is listed against 31282-425-300. The spark-advancer cover item is a rubber O-ring against 30372-425-000. Choose by the actual cover and reference rather than the shared engine-cover category.
