1972 Honda CB500K · Valvetrain Buying guide

Valve function and package quantity come first

The offered Japanese-made intake and exhaust valves have separate references. Stem-seal choices include an individually sold replacement and an eight-piece Kibblewhite set; the shoulder-style guide has its own installation-design distinction.

Parts to consider

Honda CB550 / CB500 / CB125 / CB100 Intake Valve ~ Replaces 14711-107-020 Japanese-made intake valveThe current intake-valve listing specifies replacement reference 14711-107-020 and CB500K fitment. Match it to intake duty and the head being serviced; do not substitute it for the exhaust valve.View part 1971-78 Honda CB550F / CB550K / CB500K Exhaust Valve ~ Replaces 14721-323-005 Japanese-made exhaust valveListed for the CB500K, this exhaust valve carries several Honda replacement references, including 14721-323-005. Check the full listing against the old exhaust-valve application before choosing it.View part Honda CB High Performance Kibblewhite Valve Stem Seal Set ~ Replaces 12209-333-005 Eight-piece Kibblewhite stem-seal setThis USA-made red Viton seal set is explicitly described as eight pieces, replacing reference 12209-333-005. Compare that package with the individually sold stem seal when planning the head-work order.View part

Read the current seal quantity

The individual stem-seal listing uses a historical URL containing a pack quantity, but its current description says sold each. The Kibblewhite red Viton listing explicitly supplies a set of eight. Base the order on those descriptions instead of the URL or the number of seals in a photo.

A replacement guide can use a different design

The Kibblewhite standard-size guide is described as C63000 nickel aluminum bronze and shoulder style. Its listing says it does not use separate OEM-style guide clips. Have the cylinder-head specialist confirm the required guide and fitting work; no machining clearance is supplied here.

Common questions

How should I count separately sold valves for a complete CB500K head?

Each intake or exhaust listing supplies one Japanese-made valve. The CB500K uses four of each, so complete valve replacement requires four intake valves and four exhaust valves. Choose quantities for the positions identified during the head assessment.

Should I choose individual stem seals or the Kibblewhite eight-piece set?

The separately sold seal supplies one piece; eight are required for the complete CB500K head. The Kibblewhite Viton product supplies all eight in one set. Compare the stated material and package quantity before building the order.

Do the Kibblewhite guides use the original separate guide clips?

The standard-size Kibblewhite guide has a machined shoulder and does not use separate OEM-style clips. It is sold each for intake or exhaust positions; confirm the guide design and quantity with the shop handling the head work.
