1982 Honda CB450TC · Valvetrain Parts Buying guide

Plan exhaust-valve and stem-seal purchases

The exhaust replacement references Honda 14721-413-000. Stem seals are sold individually, while the related valve-guide clip is separate hardware. Check the head inspection findings before deciding which of these parts you need.

Identify the exhaust valve before ordering

The exhaust replacement references 14721-413-000 and specifies the 1982 CB450T application. Use the engine identity and this reference together when assembling an order. Keep removed components identified by position for the person inspecting or rebuilding the head.

Order seals and clips deliberately

Each stem seal is a separate purchase. The linked valve-guide clip is also sold each and references 12211-250-310. Count these independently from the valves, and follow the service manual and machine shop’s findings for the work required.

Common buying questions

Are the stem seals supplied as an engine set?

No. The featured valve stem seal is sold individually. Order the number required for the head work being performed; the product is not a pre-counted full-engine seal kit.

What should I confirm before buying the exhaust valve?

Confirm the engine fitted and the exhaust-valve reference 14721-413-000. Have the valve, guide and seat assessed together so the order reflects the head work actually required.

Should I order a valve-guide clip with every valve?

A clip is a separate component, sold individually. Have the existing guide hardware checked during head inspection and order the number actually required rather than automatically matching the number of valves.

Not sure which part you need?

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