Keihin 24mm Carburetor; Adjustable - Genuine Buddy 125/150

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

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.
