OEM Honda Ruckus 50cc Stock Carburetor

The Genuine Honda Carburetor Assembly (Part # 16100-GGA-672) is the direct factory replacement for the reliable 49cc air-cooled 4-stroke engine in later-model Honda Ruckus scooters. This Keihin-manufactured carb features an automatic choke (enricher), precise fuel metering, and Honda's exact tolerances for smooth starting, efficient cruising, and dependable performance in daily commuting or urban riding.

Perfect for replacing a clogged, worn, or damaged stock carb—especially common on high-mileage Ruckus bikes—or refreshing after sitting for extended periods. No modifications needed; bolts directly in place with stock intake manifold and airbox.

Key Features:

• 100% Genuine Honda OEM – Guaranteed fit, quality, and longevity (avoid cheap aftermarket knockoffs that often have poor idle quality or incorrect jetting)
• Stock Jetting Included – Factory-equipped with 35 pilot jet (for idle/low-speed circuit) and 75 main jet (for mid-to-high RPM fueling)
• Automatic Choke – Reliable electric/enricher-style starting aid (common failure point on older units—replace with this for easy cold starts)
• Precision Fuel Delivery – Optimized for the stock 49cc engine's ≈2–3 hp output and EPA-compliant emissions
• Complete Assembly – Ready to install; includes throttle valve/slide, float bowl, needle valve, and all internal components
• Direct Bolt-On Replacement – Matches original Honda specs for plug-and-play installation

Vehicle Compatibility:

• Honda Ruckus / NPS50 (2008–2025+) – All variants (including NPS50S)
• Also fits select Honda Metropolitan / CHF50 (later models sharing the same carb platform; confirm via parts fiche)
