1982 Honda CB450SC Nighthawk · Engine Buying guide
Routine oil service uses the specified paper element, while valve adjustment hardware is supplied as screw-and-nut sets. An overhaul gasket set has a wider purpose, but its name does not establish the contents required for every sealing joint.
Paper filter for the original arrangementOne stock-type paper element is supplied, and one is used for the motorcycle. Compare its listed Honda references with the element and filter assembly fitted to your engine.View part
Tappet screw with matching locknutOne set contains adjuster 90012-426-000 and nut 90206-250-000 for one valve. Six sets replace all adjusters on the listed CB450 engine; order only the positions being renewed.View part

The selected parts have specific Honda references, package quantities and model applications. Compare those details with the engine on the motorcycle, especially where earlier repairs have changed components. A model name alone cannot settle the identity of an old filter, valve guide or replacement fastener.
For a localized repair, the valve-cover gasket references 12328-413-830 and the tachometer-drive seal references 91256-425-003. These identify different locations. Keep that joint-by-joint list even when considering the Athena overhaul set, whose description does not provide a complete contents schedule.
The listed CB450 engine uses six sets for complete replacement. Each supplies one 90012-426-000 screw and one 90206-250-000 locknut for one valve. Count the positions being renewed when only some adjusters need replacement.
The current seal information specifies four for the intake valves of the listed CB450 engine, with each seal sold separately. The two exhaust valves use a different seal specification, so an intake-seal order does not cover both positions.
For the valve cover, compare gasket 12328-413-830 and inspect the separate cover sealing pieces. At the tachometer drive, compare seal 91256-425-003 and its 4.8 × 14.5 × 5mm dimensions. Choose by the location being repaired.
