nibbi PE22 22mm Carburetor Kit for 110–130cc Dirt Bikes — Tunable with Jets & Anodized Finish

The NIBBI PE22 carburetor kit is a 22mm, fully tunable replacement carb with main and pilot jets, needle adjustment and anodized finish, designed to fit many 110cc–130cc dirt bikes and pit bikes.

If you’re improving throttle response, repairing a clogged factory carb, or upgrading from a PZ24-style unit, the NIBBI PE22 offers a compact, serviceable option. It ships with a selection of jets and tuning adjustments so you can match fuel delivery to your engine, and its anodized body resists wear and corrosion for longer life in dusty or wet conditions.

How does the PE22 improve engine performance?

The PE22 lets you refine air–fuel mixture using separate main and pilot jets plus needle position and an adjustable air screw. Better tuning equals smoother throttle transitions and more predictable acceleration across RPM ranges, especially after changing exhaust or intake parts.

• Main jet sizes included for high-rpm tuning and power delivery.
• Pilot jet options to smooth idle and low-throttle response.
• Needle position adjustability for midrange mixture control.
• Air screw for fine idle/part-throttle mixture calibration.

Will the NIBBI PE22 physically fit my bike?

Fitment depends on flange hole spacing and intake/bore diameters: the PE22 flange hole distance is 48mm and the engine-side inner diameter is 22mm. Measure your intake manifold and compare these dimensions before ordering, or contact the seller for fit verification.

• Flange hole distance: 48mm — check mounting bolts pattern.
• Engine-side inner bore: 22mm — matches carb throat diameter.
• Designed for common 110cc–130cc pit and dirt bikes like Apollo, TaoTao, Lifan, SSR.
• Can upgrade or replace PZ24-style carburetors with simple mount checks.

What materials and construction features matter for reliability?

The PE22 uses an anodized and coated surface that resists wear, corrosion, and the effects of dirt and fuel contaminants. Robust finish and replaceable jets/needles make field maintenance easier and extend service intervals compared with untreated cast parts.

• Anodized body for improved abrasion and corrosion resistance.
• Coated surfaces suitable for wet, muddy, or dusty riding environments.
• Replaceable jets and needle for cost-effective tuning and repairs.
• Serviceable design reduces the need for full-carb replacement.

How do I tune the carb for different conditions or mods?

Tuning the PE22 involves a combination of selecting the correct main and pilot jets, setting the needle clip position, and adjusting the air screw. Start with factory-recommended jetting for your altitude, then make small incremental changes while logging throttle response and plug color to guide further adjustments.

• Begin with supplied jet sizes and baseline needle position.
• Adjust main jet for top-end richness or leanness during full-throttle runs.
• Use pilot jet and air screw tweaks for idle and low-speed tractability.
• Consult spark plug color and throttle feel after each change.

Who this is for: The NIBBI PE22 is intended for riders, mechanics, and DIY tuners who own 110cc–130cc dirt bikes, pit bikes, ATVs or go-karts and need a compact, tunable replacement carburetor. It’s especially useful if you’re replacing a worn PZ24-style unit, upgrading intake performance after bolt-on mods, or require a corrosion-resistant carb for harsh environments. If you’re unsure about fitment, measure your flange spacing and bore size, or reach out for compatibility help before purchasing.
