Product Overview
Upgrade fuel delivery on your off-road machine with this 30mm performance carburetor kit, designed for select 150cc–250cc dirt bikes, pit bikes, ATVs, quads, go-karts, and performance scooters.
The 30mm bore provides a balanced setup for engines that need more airflow than a smaller 28mm carburetor while still maintaining good throttle response. With proper installation and jetting, it can help improve acceleration, reduce hesitation, and restore more consistent engine performance.
Made from aluminum alloy, this carburetor is built for off-road riding, heat, vibration, and demanding trail conditions.

Will this part fit my specific model and year?
This 30mm carburetor kit is suitable for many 150cc–250cc dirt bikes, pit bikes, ATVs, quads, go-karts, and scooters. It is a balanced choice for engines that need more airflow than a smaller 28mm carburetor while still keeping good throttle response.
Do I need to match the OEM part number?
This 30mm carburetor is a universal aftermarket replacement and tuning part. Please do not rely on model name alone. Compare the original carburetor’s bore size, mounting dimensions, cable style, fuel inlet position, choke type, and overall design with the product photos before ordering.
What models or situations does this part not fit?
This carburetor may not fit small engines that require a smaller carburetor, fuel-injected models, or vehicles with incompatible intake boots, airbox boots, throttle cables, vacuum ports, or choke systems. It should not be treated as a guaranteed direct replacement for every Yamaha YZ250, Kawasaki KX250, or Suzuki RM250 model.
What should I check before ordering?
Before ordering this 30mm carburetor kit, please check your original carb size, intake manifold size, air filter boot size, throttle cable end type, choke setup, and fuel line routing. Carburetor tuning or jetting adjustment may be required after installation.
