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.

Do I need to match the OEM part number?

For this carburetor, also compare the intake diameter, outlet diameter, flange/bolt spacing, choke type, throttle-cable connection, fuel/vacuum ports, and engine displacement. This is especially important for GY6 GY6 models because similar model names can use different parts by year or trim.
What models or situations does this part not fit?
Do not order this carburetor for machines outside the listed compatibility, or for units with different intake sizes, cable/choke styles, flange spacing, jetting requirements, or fuel/vacuum port layouts. Do not rely only on the model name or engine size.
What should I check before ordering?
Before ordering, compare your original part with the photos and check the intake diameter, outlet diameter, flange/bolt spacing, choke type, throttle-cable connection, fuel/vacuum ports, and engine displacement. Recheck listed specs such as Intake Diameter (Bore): 30mm (1.18"), Air Filter Mounting (OD): 46mm (1.81"), 30mm. If any connector, mounting point, size, or year detail is different, confirm fitment before installation.
