QXBER PWK 24mm Racing Carburetor Kit for 50–110cc Dirt Bikes Scooters ATV — Tunable Jets & Foam Air Filter

The QXBER PWK 24mm racing carburetor kit upgrades small-displacement 50cc–110cc 2T and 4T engines for faster throttle response, tunable fuel delivery, and easier installation.

Built for dirt bikes, scooters, ATVs and quads, this PWK-style 24mm carburetor kit provides a compact, high-flow intake package that supports performance-focused air and fuel tuning. The kit includes a pre-tuned selection of jets, a high-flow foam air filter, an intake manifold and adjustable screws—so riders can tailor mixture and idle to match exhaust, intake and elevation changes without needing specialty tools.

How does this carburetor improve throttle response and engine feel?

The 24mm venturi is sized to increase airflow over the stock carburetor, sharpening throttle response and reducing lag during acceleration. That measured increase in flow helps the engine pull harder through mid-range revs while maintaining stable idle when properly jetted.

• PWK-style 24mm bore for higher airflow and quicker spool-up
• Precision-machined fuel passages for consistent fuel metering
• Adjustable pilot and idle mixture screws to dial in low-speed response
• Comes with a range of main jets (#100–140) for tuning to altitude and mods

Will this fit my 50cc–110cc two-stroke or four-stroke engine?

The kit is designed for most horizontal and vertical carb-compatible 50cc–110cc 2T and 4T engines; the included intake manifold and common mounting flange suit many aftermarket and OEM intake boots. Confirm flange dimensions and carburetor orientation before installation to ensure proper fitment.

• Compatible range: 50cc to 110cc, 2-stroke and 4-stroke engines
• Included intake manifold adapts to common boot sizes for flexible mounting
• Compact footprint fits many dirt bikes, scooters, ATVs and quads
• Handy hardware and jets reduce the need for extra parts

What tuning and maintenance controls are included?

The QXBER PWK kit ships with multiple jets, an adjustable idle screw and an air/fuel mixture screw so you can tune the carburetor for different riding conditions, exhausts and elevation. Routine cleaning and periodic jet checks keep performance consistent.

• 10 main jets (PWK #100–140) for a wide tuning range
• Slow pilot/idle jet and adjustable fuel mixture screw for low-speed tuning
• CNC-machined idle speed screw for repeatable adjustments
• Replaceable foam air filter for easier cleaning and better filtration

How difficult is installation for a home mechanic?

Installation is straightforward for anyone familiar with small-engine carb swaps. The kit includes the major parts needed; basic hand tools and a service manual or online guide for your specific vehicle make will simplify correct jetting and setup.

• Comes with carburetor, air filter, intake manifold, jets and adjustment screws
• Simple bolt-on fit in many applications—no frame modification typically required
• Quick-start jet suggestions included via the supplied jet range
• Cleaning and minor needle/float adjustments are accessible with standard tools

Who is this for: The QXBER PWK 24mm racing carburetor kit is aimed at riders and mechanics who want a compact performance upgrade for 50cc–110cc bikes, scooters and ATVs. It suits weekend racers, off-road enthusiasts, and DIY tuners who need improved throttle response, a wide jetting range, and easy adjustability without a complete engine overhaul. If you use aftermarket exhausts or larger intake systems, or you frequently ride in varying altitudes, this kit gives the parts and tuning flexibility to match those conditions.
