CILOYU PZ26 26mm Carburetor Kit for 125–250cc CG-style Bikes and ATVs — High-Flow, Pre-Jetted

The CILOYU PZ26 26mm carburetor kit is a complete high-flow replacement designed to restore throttle response and fuel delivery on 125–250cc CG-style motorcycles and many ATV models.

If your engine is hesitating, idling rough, or not reaching top power, a worn or clogged carburetor is often the culprit. This CILOYU PZ26 kit supplies the carburetor body plus gaskets, fuel line, filters, spark plug, and mounting clips so you can replace the entire intake assembly in one service. Built for 4-stroke single-cylinder engines commonly used in pit bikes, dirt bikes and ATVs, it fits a wide range of models and includes sealing pads to cut down oil and dust ingress at the adapter joint.

Which bikes and ATVs will this PZ26 kit fit?

This kit is made for CG-style 26mm applications across many small-displacement 4-stroke machines. Check your engine and manifold dimensions before ordering to confirm fitment.

• Compatible with 125cc–250cc TaoTao, Viper, GIO, Zongshen, Buyang, Coolsport, Kazuma, Lifan, Sunl and similar pit/dirt bikes
• Common ATC/TRX models listed such as TRX200, TRX250, TRX250EX and older ATC/ATV variants
• Works with CG-style single-cylinder heads found on XR100, XR150L, CB125 and related bikes
• Measure throttle bore (26mm) and mounting flange to verify before installation

How does the high-flow design affect performance and efficiency?

The PZ26’s increased bore and optimized jetting encourage better airflow and finer fuel atomization compared with small or partially plugged stock carbs. That typically yields more immediate throttle response and improved combustion efficiency under load.

• 26mm throat for increased air volume and stronger midrange pull
• Pre-jetted but tunable—main and pilot jets can be adjusted for altitude or fuel type
• Includes fuel filters to keep contaminants out and preserve flow
• Sealing pads reduce vacuum leaks that harm mixture stability

What comes in the kit and what tools are required to install it?

The package contains everything needed for a straightforward swap from the old carburetor; basic hand tools and a small workspace are all that’s required. Allow time for warm-up and a careful tune after installation.

• 1 × PZ26 carburetor body, 1 × full gasket set, 1 × fuel hose
• 2 × inline fuel filters, 1 × spark plug, 4 × hose clips for secure fittings
• Paper and bakelite pads included to improve sealing and cut dust/oil seepage
• Recommended tools: screwdrivers, pliers, socket set, carb cleaner, basic tune kit

Will this require further tuning or adaptations after installation?

Most installations need small adjustments: pilot and main jet selection, idle speed and air-fuel mixture. If you change altitude, load, or exhaust/airbox configurations, re-jetting can optimize combustion.

• Adjust idle and mixture screws for smooth idle and steady throttle transitions
• Swap jets as needed for richer or leaner mixtures depending on conditions
• Inspect mounting boots for airtight fit; use supplied pads to prevent leaks
• Test on a safe course to verify throttle response and top-end behavior

Who is this for? The CILOYU PZ26 kit is aimed at riders, home mechanics, and small-shop technicians who need a reliable, all-in-one carburetor replacement for CG-style 125–250cc dirt bikes and compatible ATVs. It suits owners restoring older machines, upgrading a tired stock carburetor for sharper throttle response, or stocking parts for common small-displacement repairs. If you want a drop-in upgrade with mounting gaskets and filters included—plus the parts to seal the intake junction—this kit simplifies the job and gets you back on trail or track faster.
