Open box, like-new condition with original packaging. This unit has been inspected and presents as essentially new — a great opportunity to get a performance-grade carburetor at a meaningful discount from full retail.

Overview

The Nibbi PD24J is a performance replacement carburetor engineered specifically for GY6 125cc and 150cc 4-stroke CVT scooters. Built from high-strength aluminum alloy, this carb is designed to deliver precise fuel-and-air mixing, helping eliminate common GY6 headaches like hard starting, rough idling, and sluggish throttle response. Whether you're doing a routine rebuild or upgrading a worn stock unit, the PD24J is a direct-fit solution for a wide range of Chinese scooter brands running the popular GY6 engine platform.

The 24mm bore diameter makes this carb a meaningful step up in fueling efficiency over many stock units, and the aluminum alloy construction resists corrosion and holds up under sustained heat cycles. The adjustable clamp included in the kit means installation is straightforward — no specialty tools required. That said, always measure your intake manifold and air filter neck before installing to confirm fitment.
