PHBG 19mm Racing Carburetor for 2-Stroke 50cc 70cc Mopeds

Product Overview

Upgrade your 2-stroke moped, scooter, or mini bike with this PHBG 19mm racing carburetor, designed for 50cc–70cc sport setups that need quicker throttle response, smoother fuel delivery, and better mid-range acceleration.

The 19mm bore is a practical choice for riders who want improved performance without going too large for a smaller 2-stroke engine. It works well for many 50cc and 70cc platforms, including RS50, RX50, MX50, SX50-style, MBK 50, and similar 2-stroke moped or scooter builds.

Its PHBG-style design allows fine adjustment of idle, needle position, and jetting, making it suitable for tuned engines, sport cylinders, and light performance upgrades. Proper tuning is required after installation.
