DJ-2233 NIBBI 28MM CARBURETOR

DJ-2233 NIBBI PE28 28mm Performance Carburetor

The DJ-2233 NIBBI PE28 28mm Carburetor is designed for high-performance small engine applications that need increased airflow and responsive throttle control. The larger 28mm bore makes it an excellent choice for modified engines with upgrades such as performance camshafts, cylinder head work, increased compression, upgraded exhaust systems, and other performance modifications.

The PE28 features a smooth slide-style design for quick throttle response and consistent fuel delivery. Its aluminum alloy construction provides a durable, lightweight carburetor suitable for racing, go-kart, minibike, and other high-performance small engine applications.

Multiple jets are included to give you additional tuning options. Final jetting will depend on your engine combination, fuel, intake, exhaust, elevation, temperature, and other operating conditions.

For customers building a complete setup, the DJ-2233 can be paired with the 6928 NIBBI D-Shaped Carburetor Round Intake Manifold, the 6930 28mm NIBBI Carburetor Adapter, the 6899 Angled Air Filter, and the DJ-2232 NIBBI Twist Throttle Kit with Cable & Grips.
