1968 Honda CB450K Intake & Exhaust Valves

Choose valves for a 1968 Honda CB450K by position and reference, then decide quantity from the cylinder-head inspection. Intake and exhaust valves are separate products, both sold individually, so a single purchase should not be mistaken for a complete replacement set.

1968 Honda CB450K · Valvetrain Parts Buying guide

Keep intake and exhaust choices separate

The intake valve references Honda 14711-292-000. The exhaust valve references 14721-292-010 and 14721-292-000. Match the part to its position and the fitted engine; similar appearance does not establish interchangeability.

Order from the inspection findings

A valve purchase should follow an assessment of the fitted cylinder head and removed parts. Identify which positions require attention before deciding quantity. The listings establish individual valves and references, but do not make a new valve a guarantee that the rest of the valve assembly needs no work.

Keep a position-by-position parts list

Record intake and exhaust needs separately so the order remains clear when more than one valve is being replaced. Other components required for the head service are not described as included with either valve. Check those needs before placing the final order.

Buying questions

Which Honda references identify the intake and exhaust valves?

The intake valve replaces 14711-292-000. The exhaust valve lists 14721-292-010 / 14721-292-000. Each valve is sold individually. Match the inspected valve position and reference, then order the number required for the head being serviced.

How many valves does one product purchase supply?

Each listing states that the valve is sold individually. Determine the number of intake and exhaust replacements separately from the inspection, then order those quantities. Neither item is presented as a complete cylinder-head valve set.

Does buying a valve settle the rest of the head-service order?

The valve is one component. Have the surrounding head components and required service parts assessed before finalizing the order. The descriptions do not include guides, seats, seals or other hardware with the valve, and do not guarantee that replacing it alone resolves the problem.

Not sure which part you need?

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