The Honda 16561-ZDJ-000 Governor Spring is a genuine OEM component designed for the GXR120 horizontal shaft engine. Sourced directly from Honda, this spring carries the exact tension specification the governor system requires to regulate engine speed accurately. If your GXR120 is hunting, surging, or refusing to hold a steady RPM under load, a fatigued or broken governor spring is a likely cause — and this part is the correct replacement. Verify your engine's serial number against the fitment table before ordering to confirm part number 16561-ZDJ-000 is the right fit for your unit.
Key Features
- Genuine OEM Tension Spec — manufactured to Honda's exact spring-rate requirement, so the governor linkage responds correctly across the engine's full operating range
- Direct Replacement — engineered to drop into the governor assembly of the GXR120 horizontal shaft engine without modification
- Restores Speed Stability — a worn or stretched spring causes erratic RPM and poor load response; this replacement brings the governor back into calibration
- Serial Number Check Recommended — Honda updates parts at production breaks, so match your engine's serial number to the fitment table to confirm this is the correct spring for your GXR120
The governor spring is a small but critical link in the mechanical governor system of the GXR120 engine. It works in tension against the governor arm and throttle linkage, balancing centrifugal force from the governor flyweights to hold engine speed steady as load changes. When the spring weakens, stretches, or breaks, that balance is lost — the engine may surge rhythmically, overspeed, or bog down and fail to recover under load. Replacing this spring restores the precise counterforce the governor needs to keep the engine running at a consistent, controlled speed.
