CILOYU PZ26 Carburetor Kit for 125–250cc Dirt Bikes, 26mm High-Flow Direct-Fit Replacement

If your off-road bike or small-displacement ATV is running rough, hesitating on acceleration, or suffering poor fuel economy, a correctly sized carburetor and a complete installation kit can make a visible difference. The CILOYU PZ26 kit supplies a 26mm carburetor plus intake hardware and control parts to simplify swap-out and tuning for a wide range of CG/XR-style four-stroke engines and popular Chinese-made pit bikes and utility ATVs.

What engines and models will this carburetor fit?

The PZ26 is built for 26mm throat applications commonly found on 125cc–250cc single-cylinder four-stroke engines. It suits many CG/XR-derived frames and several Chinese brands and clones used in dirt bikes, ATVs, and go-karts. Always cross-check engine size and mounting flange dimensions before ordering to ensure a proper match.

• Compatible engine sizes: 125cc, 150cc, 200cc, 250cc four-stroke single cylinders
• Common model families: CG100/125, XR100/150, XR200R variants and similar clones
• Brands often compatible: TaoTao, Zongshen, Lifan, Roketa, Buyang, Sunl, Kazuma, Coolsort

How does the PZ26 kit improve performance and drivability?

This carburetor features a relatively large 26mm bore and a high-flow design to increase airflow and promote finer fuel atomization. Better mixing and more consistent fuel delivery help smooth acceleration, reduce flat spots, and can contribute to slightly improved throttle response. It’s not a substitute for engine upgrades but is an effective replacement for worn or undersized stock carburetors.

• 26mm bore for improved airflow vs smaller factory carbs
• Enhanced atomization for more consistent combustion
• Helps eliminate hesitation and uneven idle when tuned correctly

What comes in the package and what tools are included?

The kit arrives with the carburetor plus a selection of mounting and control parts to get you running without sourcing extra items. Basic hand tools are typically all that’s needed for the swap, and the included throttle cable and handle grips simplify reassembly for many common bikes.

• 1 × PZ26 carburetor and 1 × intake pipe for flange connection
• Gasket set, screws, nuts, and cable ties for secure mounting
• Accessories: throttle cable, on-off fuel switch, pair of handle grips, small wrenches

How should I install and tune a PZ26 for best results?

Installation requires matching the intake flange, connecting the throttle cable and fuel line, and sealing with the supplied gaskets. After initial start-up, set the idle mixture and pilot jet for a stable idle, then fine-tune the main jet and air screw for smooth throttle transitions across the rev range. If you’re unfamiliar with carb tuning, seek a mechanic or follow model-specific tuning guides.

• Confirm flange fit and orientation before final tightening
• Start with the stock jetting and adjust pilot/main jets as needed
• Test under load and on a range of RPMs to ensure no lean or rich spots

Who this is for: The CILOYU PZ26 kit is aimed at owners of small-displacement dirt bikes, pit bikes, ATVs, and go-karts who need a reliable replacement carburetor and a handful of installation parts. It’s a practical upgrade for hobby riders, backyard mechanics, rental fleets, and anyone swapping a worn factory carburetor for a higher-flow 26mm unit. Confirm compatibility with your engine model and flange dimensions before installing, and consider professional tuning if you need precise jetting for altitude or heavy modifications.
