1978 Honda CB550K Valves & Valve-Stem Seals

Valvetrain buying for the 1978 Honda CB550K involves more than choosing a valve brand. Intake and exhaust positions have separate references, and stem seals are offered with different sale quantities. Match the assessed components first, then compare the individual valve and seal-package descriptions.

1978 Honda CB550K · Valvetrain Parts Buying guide

Choose the valve position before the brand

Kibblewhite intake and exhaust valves are separately listed and sold each. The eight-seal Viton package is another purchase; separately offered Japanese-made valves and individual stem seals provide additional reference and quantity comparisons.

Use the position and reference to compare valve choices

The Kibblewhite intake valve references 14711-107-020 and the exhaust valve references 14721-323-005. Both descriptions say sold each. Compare the required position and removed part with the corresponding product before deciding on a brand or ordering the number of valves needed.

Distinguish the stated seal package from an individual sale

The Kibblewhite package contains eight seals and names 100% Viton construction. The separate stem-seal description says sold each. Both reference 12209-333-005, but their sale quantities differ. Check the actual seal requirement before choosing a package or calculating an order from the individual item.

Common ordering questions

Can an intake valve be chosen for an exhaust position?

The products identify separate intake and exhaust positions with different references. Match the required position and removed valve with the appropriate listing before ordering; a shared motorcycle application does not make those two valve types the same choice.

Are the featured Kibblewhite valves sold as a complete set?

Each valve description expressly says sold each and asks buyers to order the quantity needed. Count the assessed intake and exhaust requirements separately before buying, rather than treating a single valve listing as a full-engine valve package.

What material and quantity does the seal set name?

The Kibblewhite seal description names 100% Viton and a set of eight, with reference 12209-333-005. Compare the supplied quantity and required sealing positions before selecting it or combining it with the separately sold stem-seal item.
