AUTOKAY PZ20 Carburetor Kit for 50–125cc Chinese ATVs & Pit Bikes, Includes Manifold & Filters

Compact PZ20 carburetor kit by AUTOKAY designed as a drop-in aftermarket replacement for many 50cc–125cc Chinese 4-stroke ATVs, go-karts, and dirt bikes.

This AUTOKAY PZ20 kit supplies the parts needed to restore fuel delivery on a wide range of small-displacement 4-stroke machines. Built to match common OEM dimensions, the assembly includes the carburetor plus gaskets, filters, lines, an intake manifold and basic hardware so you can replace a worn or clogged unit without hunting for extra pieces. It’s intended for popular Chinese-brand models and many common 50cc–125cc pit bikes and quads.

Which machines will this AUTOKAY PZ20 carburetor work with?

The kit fits a broad set of Chinese 4-stroke vehicles and aftermarket bikes in the 50–125cc range. It’s compatible with many TaoTao and Coolster models and is commonly used on Lifan, Kazuma, Baja, and similar machines. Check your engine specs and inlet size before ordering to ensure a correct fit.

• Compatible families: TaoTao ATVs (multiple ATA models), Coolster 110/125 lines, Venom, X-pro, Icebear, Baja and more.
• Works with many 50cc–125cc pit/dirt bikes including SSR, SDG, Lifan and Xmotos models.
• Not compatible with some dedicated series (e.g., certain DB or small OEM-specific CRF50/XR50 variants); verify model fit.

How easy is installation and tuning for a non-professional?

The package is aimed at do-it-yourselfers: the PZ20 body and supplied intake pieces are designed to bolt in with common hand tools. Basic adjustments for idle speed and air/fuel mixture are accessible; if you know how to adjust a carb idle screw and mixture screw, you can tune it at the roadside or in your garage.

• Includes intake manifold, gaskets, O-ring and necessary screws for a single-unit swap.
• Comes with fuel and air filters plus a fuel line to minimize additional purchases.
• Adjustable idle and mixture screws for straightforward on-vehicle tuning.

What parts are included and why they matter?

The kit bundles the carburetor with key consumables so you don’t need extra sourcing. Fresh gaskets, a new fuel filter and a clean air filter reduce the chance of installation leaks and immediate contamination-related issues. A plug and basic mounting hardware help you complete the job in one visit to the workbench.

• Carburetor body (PZ20) sized for small 4-stroke engines.
• Gaskets, O-ring, intake manifold and mounting screws to ensure a sealed fit.
• Fuel filter, air filter, fuel line and a spark plug included for convenience.

Will this AUTOKAY carburetor last and support reliable performance?

AUTOKAY manufactures this PZ20 replacement to meet standard aftermarket quality checks for materials and machining. While aftermarket parts vary, provision of fresh seals and filters combined with correct tuning typically restores expected throttle response and starting reliability for many small bikes and quads.

• Constructed to common aftermarket tolerances for consistent fitment.
• Supplied consumables help prevent early contamination and leaks after installation.
• Designed for user adjustment to match altitude and fuel differences.

Who is this for: Riders, hobbyists and small-vehicle mechanics looking to replace a failing or clogged carburetor on 50cc–125cc Chinese-made ATVs, go-karts and pit bikes will benefit from this kit. It’s particularly useful for owners of TaoTao and Coolster models, garage DIYers who prefer a single-kit solution, and repair shops that need a reliable aftermarket option with included mounting parts and filters.
