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

High-quality AUTOKAY PZ20 carburetor kit engineered to replace worn or stock carburetors on many 50cc–125cc Chinese-made ATVs, dirt bikes, and go-karts for more reliable running and easier tuning.

Swap a tired or incompatible carburetor with this complete AUTOKAY PZ20 kit built for popular small-displacement 4-stroke machines from brands such as TaoTao, Coolster, Lifan, Kazuma and others. The kit includes the carburetor and all common installation hardware—gaskets, filters, lines and a spark plug—so you can get your engine back to smooth idling and predictable throttle response without sourcing multiple parts.

Will this PZ20 kit fit my 50cc–125cc ATV or dirt bike?

Compatibility covers many 4-stroke Chinese mini-ATVs, pit bikes and go-karts in the 50–125cc range, but fitment varies by model and manifold type. Check your engine family and intake flange size before ordering; this PZ20 is commonly used on TaoTao, Coolster, Baja, Lifan, Kazuma and related machines.

• Works with many TaoTao models (ATA‑110/125 series) and numerous Coolster 110/125 variants.
• Also compatible with Lifan, Baja, Kazuma (Falcon 90), and other 50–125cc Chinese engines.
• Not compatible with certain DB-series TaoTao models and specific mini-bikes—verify manifold shape.
• Includes intake manifold and gaskets to simplify fitment for most common flanges.

How easy is installation and basic tuning?

The kit is designed for DIY replacement with basic hand tools; the package contains the most frequently needed parts to streamline installation. Idle speed and air/fuel mixture are adjustable so you can fine-tune performance after mounting.

• Comes with intake manifold, gaskets, O-ring and mounting screws for direct swap-in.
• Includes fuel line, fuel filter and an air filter to complete the fuel tract.
• Adjustable idle and mixture screws let you tune without aftermarket parts.
• Basic mechanical experience required; follow a repair manual or online guide for torque and jet settings.

What’s included and how does the kit improve reliability?

The AUTOKAY kit supplies a rebuilt fuel system with new seals and filters which reduces leaks, clogging and inconsistent fueling that come from old carburetors. New components restore proper flow and filtration for steadier starts and smoother throttle response.

• Package contents: PZ20 carburetor, intake manifold, multiple gaskets, O-ring and screws.
• Replacement air and fuel filters plus fuel line and fuel filter help prevent contamination.
• New spark plug included for improved ignition reliability after carb swap.
• Manufactured to quality standards to resist premature wear and retain settings longer.

Who this is for: The AUTOKAY PZ20 carburetor kit is aimed at owners and mechanics of small-displacement ATVs, pit bikes and go-karts who need a complete, budget-conscious replacement to restore reliable fueling. It’s ideal if you want an all-in-one swap that includes hose, filters and hardware to avoid multiple orders. Not recommended if your model uses a different carburetor family or nonstandard manifold—confirm compatibility before purchase.
