Restore proper engine performance with this Intake Valve, designed as a direct replacement for the original Honda component. This valve replaces OEM part numbers 14711-440-003 and 14711-440-000 and is manufactured to provide reliable sealing and consistent airflow into the combustion chamber.
Over time, intake valves can wear or become damaged from heat and continuous operation. Replacing worn valves during engine service helps maintain proper compression, efficient fuel-air intake, and smooth engine performance.

Frequently Asked Questions
How many intake valves replacing Honda OEM 14711-440-003 are included and required?
One intake valve replacing Honda OEM 14711-440-003 is included. For the 1980-1982 Honda CB125S, the single-cylinder head uses one intake valve, so one is required to replace every intake 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 14711-440-003 only in the specified intake position after confirming the model, year and engine application.
What cylinder-head work should accompany a new intake 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.
