LIAMTU PZ22 ATV Carburetor Kit for 110–125cc Pit Bikes and Go-Karts — 22mm Intake, Cable Choke with Fuel & Air Filters

LIAMTU PZ22 carburetor kit is a direct-fit replacement carburetor with a fuel filter and 22mm air filter designed to restore reliable fueling on 110cc–125cc pit bikes, ATVs, go-karts and similar small-engine machines.

When an engine runs rough, stalls, or won’t reach full throttle due to a clogged or worn carburetor, replacing it with a correctly sized unit is an effective and affordable repair. This LIAMTU PZ22 kit includes the PZ22 cable choke carburetor, a compact inline fuel filter, and a 22mm (intake) air filter sized to suit many aftermarket and stock 110cc–125cc four-stroke engines. It’s built for quick installation and compatibility with popular models such as SSR, CRF50-style machines, Predator-powered bikes, Sunl and Taotao pit bikes.

How will this carburetor improve my bike’s performance?

Fitting a fresh, correctly sized carburetor improves throttle response, idling stability, and acceleration by restoring proper air–fuel mixture delivery. The cable choke design gives predictable cold starts, while the included filter elements protect the engine from debris that can cause lean running or damage.

• Correct 22mm intake diameter for many 110–125cc engines
• Cable-operated choke for easier cold starts
• Inline fuel filter reduces contaminants reaching the bowl
• Factory-caliber jetting suitable for stock configurations (may need tuning for modifications)

What measurements and fittings should I check before buying?

Confirming a few dimensions avoids fitment issues: the intake mount diameter, bolt hole spacing, and air filter throat size are key. This unit has a 22mm intake, 48mm bolting hole center-to-center, and a 38mm outer diameter on the supplied air filter mount.

• Intake mount diameter: 22mm
• Bolting hole distance: 48mm (center to center)
• Air filter diameter (listed): 38mm
• Designed for most 110cc and 125cc pit bikes, ATVs and go-karts

How hard is installation and will I need special tools?

Installation is straightforward for anyone comfortable with basic small-engine maintenance; specialized tools are not required. The kit bolts into place, connects to the throttle cable and fuel line, and typically uses the stock intake flange or a simple replacement adapter.

• Basic hand tools (screwdrivers, pliers, wrenches) generally suffice
• No advanced tuning tools required for a basic swap
• Allow time to adjust idle and check for vacuum/fuel leaks
• Contact the seller if fitment clarification is needed

Will I need to re-jet or tune after installation?

Most stock machines will run acceptably with the supplied jetting, but alterations such as larger exhausts, intake changes, or high-altitude locations may require re-jetting. Always test ride and verify air–fuel behavior; small adjustments to the pilot or main jet and idle screw can optimize performance.

• Stock-build bikes: usually plug-and-play
• Modified engines: expect possible jetting changes
• Test under real riding conditions and fine-tune accordingly

Who is this for: The LIAMTU PZ22 carburetor kit is intended for owners and mechanics of 110cc–125cc pit bikes, small ATVs, go-karts and dirt minibikes who need a dependable replacement carburetor with filters included. It’s suited to riders restoring older machines, performing routine maintenance, or swapping failed carburetors with a compact, cable-choke unit that fits common intake dimensions. If you’re unsure about compatibility, measure your intake and bolt spacing before purchase or contact seller support for fitment help.
