1971 Honda CB450K · Valvetrain Parts Buying guide

Keep valve identity and quantity on the same line

The intake product references 14711-292-000; the exhaust product references 14721-292-010 and 14721-292-000. Both state individual supply. That purchasing unit does not establish how many positions need replacement or the condition of surrounding head components.

Keep the exhaust quantity separate from the intake order.View part

Use references to avoid combining unlike requirements

Write intake or exhaust beside the relevant replacement reference in the inspection notes. A common CB450K application does not establish that the two valve types are interchangeable. If the installed engine differs from the expected arrangement, confirm the removed component and engine identity before ordering.

Let the head assessment determine the purchase

Individual supply describes how the product is sold. It does not specify a mandatory number of replacements or establish that new valves alone complete the head work. Have the surrounding components assessed with the removed valves, then list any additional parts required for the particular repair.

Buying questions

How do I order when the intake and exhaust quantities differ?

Use a separate count for each product. Intake is referenced to 14711-292-000, while exhaust lists 14721-292-010 and 14721-292-000. Each is sold individually, so the order can follow the actual inspection findings rather than an assumed combined valve set.

Can I select a valve from the motorcycle year alone after an engine change?

Confirm the installed engine and required valve reference first. Compare the removed component and its position with the intake or exhaust choice. The motorcycle’s year cannot identify an undocumented replacement engine or determine the valve needed by that engine.

What else should be decided before completing a valve order?

Establish the condition of the cylinder head and surrounding components with the removed valves. The descriptions identify individual replacements, not a complete supporting-parts package or an assessment of your engine. Add other required service parts separately from the findings.

Not sure which part you need?

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