YOXUFA PZ19 19mm Carburetor for 50–125cc Pit Bikes & ATVs — Hand Choke, 7/8in Throttle Kit

If you need a reliable, direct-fit replacement carburetor for a range of small Chinese-made motorcycles and ATVs—TaoTao, Apollo, Coolster, Baja, SSR, Xmotos and similar models—the YOXUFA PZ19 offers an off-the-shelf option with the common 19mm bore, a pre-installed hand choke, and a 7/8" throttle grip and cable assembly. The kit arrives with an air filter, fuel line, fuel filters, clamps and a gasket set so you can swap the unit with minimal additional parts.

Will this carburetor fit my 110cc or 125cc pit bike?

Compatibility centers on bore size and throttle/handlebar standards. The PZ19 has a 19 mm internal bore and is intended for many 50cc–125cc Chinese four-stroke models; it usually fits engines that accept PZ19 carb patterns and 7/8" throttle grips.

• Internal diameter: 19 mm; outer airbox side diameter: 32 mm.
• Included throttle grip sized for 7/8" (22 mm) handlebars.
• Throttle cable length: 127 cm (50 in) for flexible routing.
• Designed for common mini pit bikes, quads and small ATVs from Chinese manufacturers.

What does the kit include and how complete is it for installation?

The YOXUFA kit is packaged as an install-ready carburetor assembly with most small parts you’ll need. It reduces the number of extra purchases, though some bikes may still require adapter boots or unique clamps depending on their intake manifold.

• 1x PZ19 carburetor with hand choke.
• 1x red air filter, 1x fuel line, 2x inline fuel filters, 4x clamps, and a gasket set.
• 1x throttle housing, 1x black throttle cable (127 cm), and 1x throttle handle grip.
• Basic clamps and gaskets for a typical direct-fit swap.

How does the hand choke and throttle assembly affect performance and usability?

A hand choke simplifies cold starts for small engines by enriching the mixture without modifying jets. The included 7/8" throttle grip and 50" cable fit most mini-bike handlebars and allow straightforward replacement of worn controls.

• Hand choke provides easy cold-start control without linking to a manual cable choke.
• 7/8" throttle grip matches common mini bike handlebars for quick swaps.
• 50" cable offers generous routing options behind tanks and frames.
• Air filter and inline filters help keep particulates out of the bowl and jets.

Who is this product for? The YOXUFA PZ19 carburetor kit is aimed at owners and mechanics of small-displacement four-stroke pit bikes, mini dirt bikes, and quads—especially those riding Chinese-made models that accept PZ-style 19mm carbs. It’s a practical choice when the original carburetor is leaking, clogged, or worn, and for anyone wanting a one-package replacement that includes throttle hardware and basic consumables. If your machine’s intake flange, cable routing, or handlebar diameter differ significantly, check measurements first or be prepared to add a manifold adapter or different length cable. Professional installation is recommended if you’re unfamiliar with carburetor syncing, jetting, or fuel-system plumbing.
