1971 Honda CB500K Valvetrain Parts

Each valve listing supplies one valve. The CB500K uses four intake and four exhaust valves, so a complete replacement requires four of each. Order for the positions your cylinder-head assessment identifies rather than assuming one listing supplies a set.

The current guide description explicitly identifies a shoulder-style design that does not use separate OEM-style valve-guide clips. Confirm that design with your cylinder-head specialist before adding original-style clip hardware to the same order.

The seal replacing 12209-333-005 is sold each, and the CB500K head uses eight. Order eight for complete stem-seal replacement, or count the individual positions being serviced; the product photograph does not establish a larger supplied pack.
