nibbi 24mm Carburetor Kit for 140-150cc Dirt Bikes — PE24 with Jets, Anodized Durable Finish

The NIBBI PE24 is a 24mm aftermarket carburetor kit engineered to replace stock PZ26/PZ27 units and tune fuel delivery on 140–150cc dirt bikes, pit bikes, and compatible ATVs.

This carburetor package includes the PE24 body and a selection of carb jets to help optimize air/fuel mixture for a range of conditions and engine builds. Built with an anodized, coated surface for corrosion and wear resistance, the PE24 is designed to withstand off-road environments while offering the user more tuning control than many stock units. Before ordering, verify that your intake flange hole spacing (48mm) and intake inner diameter (24mm) match your bike’s manifold.

How does the PE24 improve throttle response and tuning options?

The PE24 gives riders more precise control over fuel metering than many stock carburetors by offering adjustable pilot and main jets, needle position, and an adjustable air screw. These adjustments let you dial in richer or leaner mixtures as altitude, temperature, and engine modifications change. For riders who tow, race, or modify engines, this flexibility helps achieve smoother throttle transitions and improved midrange power.

• Adjustable main jet and pilot jet sizes included for tuning range
• Needle clip positions allow fine mid-throttle calibration
• Air screw improves idle and low-speed mixture control

Will the NIBBI PE24 fit my 140–150cc dirt bike, pit bike, or ATV?

The PE24 is commonly used on 140cc–150cc engines and is compatible with many makes such as Apollo, TaoTao, Lifan, Kayo, SSR and similar models. Key dimensions to confirm are the carburetor flange hole spacing of 48mm and the engine-side inner diameter of 24mm. If your bike currently uses a PZ26 or PZ27 style carburetor, the PE24 can be used as an upgrade in most applications.

• Engine size compatibility: 140cc–150cc recommended
• Flange hole spacing: 48mm — measure your manifold to confirm
• Inner bore: 24mm engine-side diameter

What materials and construction details make this carburetor durable?

The PE24 features an anodized and coated finish to resist corrosion and wear from fuel and off-road exposure. That surface treatment extends usable life in dusty, wet, or high-vibration conditions frequently encountered in trail and race riding. Internal components are designed for serviceability so jets and needles can be changed as needed.

• Anodized, coated exterior for corrosion and abrasion resistance
• Replaceable jets and needle for long-term tuning and repair
• Bolt-on design simplifies replacement of PZ26/PZ27 carbs

How do I install and tune the PE24 for best results?

Installation is a straightforward swap for compatible manifolds: remove the old carburetor, fit the PE24 to the intake flange using the 48mm bolt pattern, and reconnect throttle and fuel lines. Start with the stock jetting provided, then make incremental changes to the needle, pilot, or main jet while logging running conditions. Small adjustments and test rides help you find the optimal setting for your altitude, load, and rider style.

• Start with supplied jets, then test and adjust gradually
• Use needle clip changes for midrange tuning, jets for extremes
• Confirm secure throttle cable and fuel line routing after fitment

Who is this for: The NIBBI PE24 carburetor kit is intended for riders of 140–150cc dirt bikes, pit bikes, and similar ATVs who want a durable upgrade from stock PZ26/PZ27 carburetors and wider tuning capability. It suits hobbyists who tune their own machines, shop mechanics replacing worn carbs, and athletes seeking more precise throttle control. Verify manifold dimensions and basic mechanical aptitude before purchasing to ensure proper fit and setup.
