1974 Honda CB450K · Valvetrain Parts Buying guide

Identify the position before setting the purchase quantity

The intake valve references 14711-292-000. The exhaust product names 14721-292-010 and 14721-292-000. Both explicitly supply an individual valve, without an itemized head-service kit or every fitted-engine measurement described.

Parts to consider

Carry the inspection result into the order quantities

The descriptions identify replacement valves and their purchasing units, but do not assess the condition of the head on your motorcycle. Keep the required intake count and exhaust count from the service assessment separate. Identify other components needed for that work rather than interpreting either valve purchase as a complete repair kit.

Resolve an altered head before relying on the year heading

Record the head and valve arrangement fitted if previous engine work changed them. Compare the required references and obtain any missing measurements before selecting replacements. A common CB450K application does not document that modification or establish dimensions omitted from the individual valve descriptions, and no fitting procedure is supplied by that application alone.

Buying questions

How should I place an order when only one exhaust valve is required?

Choose the exhaust product against its 14721-292-010 / 14721-292-000 references and its individual supply statement. Use the assessed quantity rather than a presumed full-head package. Check any separately required hardware with the service plan before completing that repair order.

What should I establish if the valve’s original reference is unknown?

Identify the fitted head, the valve position and the replacement requirement from appropriate parts information. Compare the removed valve and confirm missing dimensions where necessary. The intake and exhaust application lists do not resolve an unidentified modified valve solely from the motorcycle year.

Which accompanying parts are confirmed by these valve purchases?

Each description confirms an individual valve without a listed set of guides, springs or other head hardware. Compare the assessed job’s additional requirements separately. An appropriate replacement reference does not establish that every component needed for valve work arrives with the valve.

Not sure which part you need?

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