1979 Honda CB750L Engine Covers & Seals

The Limited cover selection includes a chrome spark-advancer cover and separate sealing pieces. Match the actual cover being repaired before ordering. A cosmetic cover refresh and a starter-cover reseal are different jobs, even when both products appear in this category.

1979 Honda CB750L Limited · Engine Covers & Seals Buying guide

Refresh the correct cover and its seal

The chrome spark-advancer cover replaces reference 30371-425-010. Its rubber sealing gasket is separate, allowing the cover and seal to be chosen according to their individual condition.

Separate appearance from sealing

Replace a damaged chrome cover when its condition warrants it, and inspect the gasket at the same time. Buying the cover does not supply the rubber seal. Match both parts to the Limited ignition-side assembly before preparing the repair.

Name the cover before ordering

The related starter motor cover gasket serves another location. Use the engine diagram and removed gasket outline to avoid confusing similar cover descriptions. Keep the original mounting hardware organized and refer to the manual for the correct assembly procedure.

Buying questions

Does the chrome cover include a gasket?

No. Its product description specifies a separate gasket. The featured rubber O-ring is the corresponding spark-advancer cover sealing part, so assess whether your existing seal also needs replacement.

Can I keep the cover and replace only its gasket?

The rubber gasket is available separately from the chrome cover. Inspect the existing cover and its sealing surface, then choose a gasket-only repair if the cover remains suitable for reuse.

How should I check a cover on a modified engine?

Compare the installed cover, fixing points and sealing outline with the spark-advancer cover reference 30371-425-010. A changed engine or cover needs that check rather than relying only on the Limited model name.
