Frequently Asked Questions

How many exhaust valves replacing Honda OEM 14721-437-000 are included and required?

One exhaust valve replacing Honda OEM 14721-437-000 is included. For the 1980-1985 Honda CB125S, the single-cylinder head uses one exhaust valve, so one is required to replace every exhaust valve in one engine.

Can an intake valve and an exhaust valve be substituted for one another?

No. Intake and exhaust valves can differ in head diameter, stem dimensions, material and heat capacity. Install Honda reference 14721-437-000 only in the specified exhaust position after confirming the model, year and engine application.

What cylinder-head work should accompany a new exhaust valve?

Measure the valve guide and stem clearance, inspect the seat and spring, and verify installed height and valve clearance to the Honda service manual. A new valve will not correct a worn guide or damaged seat by itself.
