RUTU PZ22 38mm Carburetor Kit for 110–125cc ATVs Pit Bikes — Zinc Alloy Body & High-Flow Air Filter

RUTU PZ22 38mm carburetor kit — a complete replacement carburetor and intake accessory set designed to restore reliable fueling and smoother throttle response on most 110cc–125cc Chinese 4-stroke ATVs, pit bikes and go-karts.

This PZ22 kit is tailored for small-displacement four-stroke engines commonly used on recreational off-road vehicles and entry-level motorcycles. Built from zinc alloy for sturdiness and improved sealing, the assembly includes a tuned air filter, fuel lines and mounting gaskets so you can swap it in quickly. It works with a wide range of Chinese-brand machines (Kazuma, SunL, TAOTAO, Roketa and similar) where a 38mm PZ-style carburetor is specified.

How does this carburetor improve engine performance?

The PZ22 supplies a more precise fuel/air mix than many worn or factory-stock carbs, which helps the engine run more consistently across throttle positions. Better atomization and reduced vapor loss can make starts crisper and throttle transitions smoother without modifying the engine internals.

• 38mm bore size suited to 110–125cc four-stroke engines for balanced airflow.
• Zinc alloy body for tighter sealing and less fuel seepage than cast-aluminum alternatives.
• Included high-flow air filter for cleaner intake and steady delivery.

What comes in the kit and how easy is installation?

The package supplies everything needed to replace a PZ-style carburetor so you can install it with basic tools. Included parts remove the need to hunt down separately sold hoses or clips, simplifying fitment on compatible machines.

• One PZ22 carburetor and a compatible 38mm air filter ready to mount.
• Two fuel filters, a red PU fuel line, steel hose clips and two gaskets for a complete hookup.
• User-friendly connections and standard fittings for quick swap-outs on most 110–125cc Chinese ATVs and go-karts.

Will this carburetor fit my vehicle and what brands are compatible?

This PZ22 kit targets a wide group of Chinese-made 4-stroke small-displacement vehicles that accept a 38mm PZ-style carburetor. Check your engine’s intake flange and throttle cable orientation to confirm compatibility before ordering.

• Compatible with many 110cc and 125cc models and often adaptable to 50–90cc models using the same mount style.
• Common fits include Kazuma, SunL, TAOTAO, Roketa, Coolster, Buyang, NST, Tank and similar brands.
• Measure flange diameter and compare throttle linkage type when in doubt to avoid fitment issues.

How durable are the materials and hoses supplied?

The carburetor body is cast from zinc alloy to resist corrosion and maintain tighter tolerances over time. Fuel lines are upgraded PU material, chosen for oil and fuel resistance to reduce splitting or hardening that can cause leaks after extended use.

• Zinc alloy body for long-term resistance to wear and better sealing performance.
• PU fuel lines reduce crack risk vs. standard rubber lines in high-heat or age conditions.
• Supplied steel hose clamps and spare fuel filters add practical durability to the installation.

Who is this for: The RUTU PZ22 38mm carburetor kit suits owners, hobbyists and small-shop mechanics wanting a reliable, ready-to-install replacement for 110cc–125cc Chinese 4-stroke ATVs, pit bikes and go-karts. It’s ideal if you need a full parts bundle (carburetor, air filter, hoses and fittings) to restore proper fueling, reduce vapor loss, and cut the time spent sourcing separate components. If your vehicle uses a PZ-style intake and you want improved sealing and longer-lasting fuel lines, this kit is a practical, cost-effective option.
