1979 Honda CB400TII Hawk II Engine Parts

Begin an engine order with the job you are doing: routine oil service, a leaking cover or a measured cylinder rebuild. The 1979 Hawk II is a twin, so piston-kit quantities and component choices should follow its own engine layout.

1979 Honda CB400TII Hawk II · Engine Parts Buying guide

Build the order around the work ahead

These choices cover everyday filtration, engine sealing and piston replacement. Establish which assemblies will be opened before buying, then use the narrower engine sections to match individual service parts.

Choose a sensible repair scope

A routine oil service starts with the paper element and inspection of the filter housing hardware. A cover leak needs its source identified before parts are ordered. The Athena overhaul set suits a broader teardown; match its contents to the engine joints you expect to open.

Order for a twin-cylinder engine

Each standard piston kit supplies one piston, rings, a pin and clips. Replacing both pistons therefore calls for two kits. Have the cylinders measured first: a standard-size label is a size choice, not evidence that worn or previously machined bores remain suitable.

Ordering questions

How many piston kits cover the complete engine?

Two kits cover the Hawk II’s two pistons. Each kit contains the parts for one piston; confirm that standard size is appropriate for both cylinders before placing the order.

Which filter is intended for the original housing?

The stock-type paper element replaces reference 15412-413-005. Compare the fitted housing if the motorcycle has been modified, and check its retaining hardware during service.

Should I buy the overhaul gasket set for a cover leak?

Identify the leaking joint first. A separate valve-cover gasket is a more focused choice when that is the only joint being opened; broader dismantling calls for a repair-specific gasket list.

Not sure which part you need?

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