nibbi PE24 24mm Carburetor Kit for 140–150cc Dirt Bikes — Anodized Alloy, Jet Tuning Kit

The NIBBI PE24 is a 24mm replacement carburetor kit engineered to upgrade or replace PZ26/PZ27 units on 140cc–150cc dirt bikes and pit bikes, complete with main and pilot jets, needle and tuning hardware.

This compact carburetor kit provides a practical performance and service upgrade for small-displacement off-road motorcycles, pit bikes, ATVs and go-karts. Built with an anodized, corrosion-resistant finish and a removable jet setup, the PE24 gives riders more control over fuel metering and easier maintenance compared with many stock carbs. Confirm the flange spacing (48mm) and the 24mm engine-side bore before ordering to ensure fitment.

Will the NIBBI PE24 fit my 140cc or 150cc dirt bike?

Fit depends on the carburetor flange hole spacing and intake bore. The PE24 flange hole distance measures 48mm and the inner engine-side diameter is 24mm, so it replaces many PZ-series carbs but you should verify your current carb dimensions first.

• Flange hole spacing: 48mm
• Engine-side inner diameter: 24mm
• Common replacements: PZ26/PZ27 upgrades
• Compatible machines: 140cc–150cc dirt bikes, pit bikes, Apollo, TaoTao, Lifan, SSR, Kayo, Xpro

How does this carburetor help with tuning and rideability?

The PE24 kit includes selectable main jets, pilot jets and an adjustable needle position, plus an air screw for fine idle mixture control. Those tuning options let you optimize fuel/air delivery across throttle positions to match altitude, fuel quality and exhaust changes.

• Replaceable main and pilot jets for richer or leaner mixtures
• Adjustable needle height for mid-range response
• Air screw for idle and low-throttle tuning
• Quick swap jet setup simplifies trackside adjustments

What are the construction and durability features of this carburetor?

NIBBI PE24 bodies have an anodized and coated surface to resist wear and corrosion found in off-road environments. The finish and materials are chosen to tolerate vibration, dust and moisture common to dirt-bike use while keeping throttle response stable.

• Anodized exterior resists corrosion and abrasion
• Coated surfaces reduce sticking and contaminants buildup
• Serviceable design for routine cleaning and jet replacement
• Compact 24mm bore suitable for 140–150cc engines

How difficult is installation and what should I check before buying?

Installation is straightforward for anyone comfortable with basic carb work: remove the old carb, match bolt and flange dimensions, mount the PE24, reconnect throttle and fuel lines, then tune. You may need different intake or manifold adapters on non-standard frames, and a short break-in tuning pass is recommended after fitment.

• Confirm flange hole spacing (48mm) and 24mm bore before purchase
• May require intake or manifold adapter on some frames
• Throttle cable and fuel line reattachment are standard steps
• Initial jetting check and minor adjustments likely needed

Who is this for: The NIBBI PE24 kit is intended for riders and mechanics who want a durable, tunable replacement carburetor for 140cc–150cc dirt bikes, pit bikes, ATVs or go-karts. It suits owners upgrading worn PZ-series carbs, tuners who need easier jet access trackside, and anyone needing improved serviceability and corrosion resistance in off-road conditions. If you’re unsure about fitment or need help matching adapters, consult the seller with your bike’s current carb measurements and manifold type.
