The Honda 14721-ZE2-W00 Exhaust Valve (Stellite) is a genuine OEM replacement designed for GX240 and GX270 horizontal shaft engines. As a direct OEM part, it is manufactured to the same specifications as the original component that left the factory, ensuring a proper fit within the valvetrain. Honda supersedes parts at defined serial number breaks, so confirm your engine's serial number against the fitment table before ordering to make sure part number 14721-ZE2-W00 is the correct valve for your unit.
Key Features
- Stellite-Grade Exhaust Valve — the Stellite facing on this exhaust valve is engineered to withstand the elevated temperatures and repeated impact that the exhaust side of the valvetrain generates, making material grade the critical factor for long service life here.
- Genuine Honda OEM Part — sourced directly from Honda, this valve is manufactured to the exact dimensions required for correct seating, sealing, and stem clearance in the GX240 and GX270 cylinder head.
- Fits GX240 and GX270 Horizontal Shaft Engines — confirm your engine model and serial number against the fitment table, as Honda revises part numbers at serial breaks and not every serial range uses the same valve.
- Restores Compression and Combustion Efficiency — a worn or burned exhaust valve allows combustion gases to escape past the seat, causing loss of compression, rough running, and hard starting; replacing it restores the sealed valve-face-to-seat contact the engine depends on.
The exhaust valve controls the release of burned gases from the combustion chamber at the end of each power stroke. It opens on the exhaust stroke to let spent gases escape through the exhaust port, then closes and seals tightly against its seat to contain compression during the intake and compression strokes that follow. On the exhaust side, the valve face is exposed to extreme heat and repeated hammer-like contact with the seat, making it the valvetrain component most vulnerable to recession, burning, and pitting. When an exhaust valve fails to seal completely, compression drops, power falls off, and the engine becomes difficult to start — replacing it with the correct OEM part is the straightforward path to restoring normal engine operation.
