1979 Honda CB400TII Hawk II · Engine Gaskets Buying guide

Choose gaskets for a cover repair or teardown

The individual cover gasket gives a defined replacement for one location. The overhaul set is the broader option, but a detailed repair list should still guide the contents check.

A focused cover repair

The separate Athena gasket is intended for the valve cover and carries reference 12328-413-830. Check the cover and mating surfaces while diagnosing a leak. Choosing the gasket for that exact joint keeps a small repair from becoming an unnecessarily broad parts order.

A planned overhaul

Use the overhaul set when several engine joints will be opened. Before ordering, compare the current package contents with the repair plan, especially any separately required oil seals or small sealing rings. A set name alone is not an itemized inventory for every possible engine job.

Ordering questions

Can I order just the valve-cover gasket?

Yes. The separate Athena valve-cover gasket is listed for the 1979 CB400TII and replaces reference 12328-413-830. It provides a targeted choice when that cover is the repair location.

Is the Athena set suitable for this year?

The overhaul set explicitly includes the 1978–79 CB400TII application. Use that engine identification along with the repair scope, especially if the motorcycle has received a replacement engine.

How do I avoid buying duplicate gaskets?

Write down the joints to be opened and compare them with the set contents before adding separate pieces. Confirm any essential small seals with the merchant when they are not itemized.

Not sure which part you need?

Send your model and year, plus photos of your existing part and any changes to the original setup.
