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

This compact performance carburetor delivers a durable, serviceable fuel-delivery solution for small-displacement off-road engines. Anodized and coated for corrosion and wear resistance, the PE24 offers tunable jets and needle settings so you can match fueling to altitude, load and riding style. Check flange spacing (48mm) and the 24mm engine-side bore before installing; consult the seller if you need help confirming fitment.

How does the PE24 improve performance on a 140–150cc bike?

The PE24 provides a more precise air–fuel mixture compared with many worn OEM carbs, improving throttle response and usable power across the rev range when tuned correctly. Its replaceable jets and needle give you fine control over fueling for different conditions.

• 24mm engine-side bore tuned for small-displacement motors
• Adjustable main and pilot jets for richer or leaner mixtures
• Needle and air screw adjustments for midrange and idle control
• Anodized coating for long-term durability in dusty or wet environments

What fitment and dimensions should I verify before buying?

Measure the flange-to-flange hole spacing and the intake bore to confirm compatibility. The PE24 flange hole distance is 48mm and the internal diameter on the engine side is 24mm; these are critical for a bolt-on replacement.

• Flange hole spacing: 48mm (center-to-center)
• Engine-side inner diameter: 24mm
• Designed to replace PZ26/PZ27 style carburetors on 140–150cc engines
• Contact seller with bike make/model if uncertain about fit

Which tuning options are included and how do they help?

The kit includes multiple jetting and needle adjustment options so you can dial fuel delivery for altitude, temperature and riding load. These tuning points let you refine idle quality, acceleration response and top-end mix without buying additional parts.

• Main jet: adjusts high-rpm fueling
• Pilot jet: controls low-speed and idle mixture
• Needle position: alters midrange richness
• Air screw: fine-tunes idle and transition behavior

What materials and maintenance should I expect?

The body receives an anodized finish and protective coating for corrosion and abrasion resistance suited to off-road use. Routine maintenance—cleaning passages, inspecting the float and replacing jets when worn—keeps the carburetor operating reliably.

• Anodized and coated exterior resists corrosion and wear
• Serviceable jets and needle for field tuning or repair
• Periodic cleaning prevents clogging from ethanol or debris
• Simple gasket and float replacement keeps parts fresh

Who is this for: The NIBBI PE24 suits riders and mechanics who want a rugged, tunable carburetor for 140–150cc dirt bikes, pit bikes, go-karts, ATVs and similar small-displacement machines. It’s ideal if you’re replacing a worn PZ26/PZ27, need better throttle response, or want the flexibility to tune fueling for different elevations and riding styles. If you’re unsure about mounting dimensions, measure the 48mm flange spacing and 24mm intake bore or contact the seller for fitment help before purchase.
