Product Overview
Upgrade your 2-stroke performance build with this PHBL 25BS Racing Carburetor. This 25mm carburetor is designed for riders working with 125cc–150cc tuned 2-stroke scooter, motorcycle, ATV, or dirt bike builds and looking for mid-range acceleration and a practical racing upgrade for many tuned engines.
The PHBL racing-style design supports stable fuel delivery and improved air-fuel control for modified small-engine applications. It is commonly used on 2-stroke scooters, motorcycles, dirt bikes, ATVs, and other powersports builds where the original carburetor is no longer enough for the engine setup.
This is a performance carburetor, so proper setup is important. Intake fitment, throttle cable style, air filter size, jetting, idle adjustment, and engine modifications should be checked before installation.

Choose the Right PHBL Carburetor Size
