FVRITO PZ20 Carburetor Thumb Throttle Kit for 50–125cc Chinese ATVs — PZ20 Carb, Air Filter & Thumb Controller

The FVRITO PZ20 Carburetor Thumb Throttle Kit is a complete replacement and upgrade package that fits most 50cc–125cc Chinese 4-stroke ATVs and includes the PZ20 carb, air filter, intake manifold, thumb throttle, cable, grips and installation hardware.

This kit is built to refresh worn fuel systems or to upgrade from smaller or older carb sizes on TaoTao, Coolster, SunL, Kazuma, Baja and many other popular Chinese ATV/quad models. It balances throttle response, fuel economy and affordability by landing between the leaner PZ19 and the larger PZ22 in performance characteristics. The kit arrives ready to install with common gaskets, fuel line components and a spark plug so you can get back on the trail quickly.

Which ATVs and engines will this PZ20 kit fit?

The PZ20 carburetor and throttle kit is designed for a wide range of 4-stroke Chinese ATVs from about 50cc to 125cc. It matches many factory intake bolt patterns and throttle controls used by mainstream aftermarket parts.

• Compatible with TaoTao models (ATA-110/125 series), Coolster 110/125 variants, Venom, Icebear, Baja and many others.
• Works with engines from brands like Lifan, Loncin, Kazuma, Roketa and Vitacci when specs match.
• Thumb controller designed for 7/8" (22 mm) handlebars; cable length 46.5" (1180 mm).

How does this kit affect performance and fuel economy?

The PZ20 sits between the PZ19 and PZ22 in flow capacity, offering a noticeable performance uplift over PZ19 setups while keeping fuel consumption more conservative than PZ22 options. It’s a practical choice when you want stronger throttle response without dramatically worsening mileage.

• PZ20 carb provides improved mid-range power and smoother throttle transitions.
• Includes air filter and intake manifold to optimize airflow and filtration.
• Comes with a fuel shut-off valve and inline filters to protect the carb and improve longevity.

What parts are included and what sizes should I check before buying?

The kit ships with everything typically needed for a straightforward replacement on compatible quads. Confirm your handlebar diameter and intake flange match before ordering to avoid fit issues.

• Includes: PZ20 carb, 35 mm air filter, intake manifold, thumb controller, 46.5" accelerator cable, two 7/8" handle grips, inline fuel petcock, spark plug and mounting hardware.
• Thumb controller and grips fit 7/8" (22 mm) handlebars; grip length 117 mm.
• Inner diameter and cable length are specified so you can compare to your existing parts before purchase.

How easy is installation and what should I prepare?

Installation is beginner- to intermediate-level for owners comfortable with basic ATV maintenance. The kit includes gaskets, O-ring and necessary clips, but basic hand tools and a clean workspace are recommended.

• Expect to replace the carburetor, mount the intake manifold, attach the throttle cable and fit the thumb controller and grips.
• Have screwdrivers, pliers and a wrench set ready; check carb and manifold bolt patterns for alignment.
• After install, adjust cable freeplay, inspect for fuel leaks, and tune idle/mixture as needed.

Who this is for: Riders and DIY mechanics who own TaoTao, Coolster, SunL, Kazuma, Baja or similar 50cc–125cc Chinese 4-stroke ATVs and need a reliable, affordable carburetor replacement or modest performance upgrade. It’s especially useful for machines with a worn carb or for owners moving up from a PZ19 who want better throttle response without a large fuel trade-off.
