The Keihin 24mm CVK Adjustable Carburetor is the ultimate "set-it-and-forget-it" fueling solution for the Genuine Buddy. While it shares the same high-performance design as the factory original (Genuine #C21510010004), this version features an accessible mixture screw, allowing you to fine-tune your air/fuel ratio for better idling and smoother throttle response.
Whether you are compensating for altitude, a performance exhaust, or a high-flow air filter, this carburetor provides the tuning flexibility that standard "non-adjustable" units lack. It comes complete with an integrated auto-choke and accelerator pump for reliable cold starts and crisp acceleration.
Performance Features:
- Tuner-Friendly: Equipped with a fuel/air mixture adjustment screw (Note: Some units may require a D-Screw Tool).
- Consistent Fueling: CVK (Constant Velocity) design ensures smooth power delivery across the entire RPM range.
- Ready to Bolt-On: Includes pre-installed auto-choke and accelerator pump assembly.
Technical Specifications:
- Venturi Size: 24mm
- Engine Side (ID): 34mm Outer Diameter
- Airbox Side (ID): 43mm Outer Diameter
- Compatible Main Jets: Genuine 4mm / Main Jet Kit
- Compatible Idle Jets: Keihin Idle Jets
Model Compatibility:
- Genuine Buddy 125 (All Years)

Tech Tip: If your scooter is stalling at stoplights or hesitating when you twist the throttle, your mixture is likely too lean. Start by turning the mixture screw out in 1/4 turn increments until the idle stabilizes.
