Carburetor CVK 30mm for 150cc–250cc GY6 Scooter, ATV, Dirt Bike

GOOFIT CVK 30mm High-Performance Constant Velocity Carburetor

Experience smoother power and higher top speeds. The GOOFIT CVK 30mm Carburetor is a premium upgrade for 150cc, 200cc, and 250cc 4-stroke engines. Unlike standard carburetors, the CVK (Constant Velocity) design uses a vacuum-operated slide to maintain consistent air velocity, providing a much smoother throttle transition and superior fuel economy for daily commuting and long-distance touring.

Crafted from high-hardness, industrial-grade metal, this carburetor is built for maximum strength and a long service life. It is the most effective bolt-on modification to increase your engine's performance, providing the rapid fuel delivery needed to reach higher speeds without the "stuttering" often found in factory-grade units.
