PZ25 Carburetor Complete Assembly 70‑125cc Chinese ATV Dirt Bike Pit Bike Carb 22mm–25mm Hand Choke

OVERVIEW

This complete PZ25 carburetor assembly restores proper fuel delivery and throttle response for 70cc through 125cc Chinese ATVs, dirt bikes, and pit bikes. Designed as a direct replacement unit, it mounts to engines featuring a 22mm–25mm intake bore and replaces factory carbs on vehicles from major manufacturers without requiring custom fabrication.

ENGINEERING & PERFORMANCE

This PZ25 carburetor arrives fully assembled and pre-jetted for stock engines, providing immediate usability out of the box while allowing fine-tuning adjustments once installed. The integrated hand choke lever ensures reliable cold starts consistent across 4-stroke engines commonly found in this displacement range.
