Product Overview
Upgrade airflow and throttle response with this 34mm performance carburetor kit, designed for select 250cc dirt bikes, ATVs, quads, go-karts, and high-output off-road builds.
The 34mm bore is intended for larger or more performance-focused 250cc engines that can use increased airflow. With proper installation and jetting, it can help improve throttle response, reduce mid-range bogging, and support stronger top-end power.

Fitment FAQ
Will this part fit my specific model and year?
This 34mm carburetor kit is recommended for select 250cc performance builds, dirt bikes, ATVs, quads, go-karts, and custom off-road applications. It may be used for some YZ-style, KX-style, or RM-style builds, but fitment depends on carb size, intake connection, air filter connection, throttle cable, choke type, and tuning setup.
Do I need to match the OEM part number?
This is a universal aftermarket carburetor and does not replace one fixed OEM part number. Supplier references may include YZ250, KX, and RM-style applications, but buyers should confirm fitment by measurement. Please compare bore size, intake diameter, outlet diameter, throttle cable connection, choke type, fuel inlet location, and overall shape before ordering.
What models or situations does this part not fit?
This carburetor is not guaranteed to fit every Yamaha YZ250, Kawasaki KX250, or Suzuki RM250. Many full-size 250cc race bikes use model-specific carburetors, larger carburetor sizes, or fuel injection systems. It may not fit EFI models, stock airboxes with different boot sizes, or engines requiring special vacuum, emission, or electronic connections.
What should I check before ordering?
Before ordering this 34mm carburetor kit, please make sure your engine, intake manifold, air filter boot, throttle cable, choke setup, and fuel system are compatible with a 34mm carburetor. Larger carburetors usually require proper jetting and tuning to perform correctly.
