Compatibility & Fitment

This kit is a universal upgrade for most Chinese-manufactured 110cc and 125cc 4-stroke horizontal engines. Key compatible brands and models include:

  • Dirt Bikes: SSR 110, SSR 125, CRF50 (with 22mm upgrade), Apollo RFZ, Coolster, Piranha.
  • ATVs & Quads: TaoTao (110cc/125cc models), Coolster 3050/3125, Mountopz, Peace Sports.
  • Mini Bikes & Go-Karts: Coleman Powersports (select 110cc models), Predator 110, Hammerhead.
  • Engine Specifications: Fits horizontal engines from Loncin, Lifan, Zongshen, and Ducar.

When to Replace

  • Difficulty Starting: The engine requires repeated kicks or turns even when the choke is engaged, often due to clogged internal pilot jets.
  • Hesitation or "Bogging": The engine sputters or dies when the throttle is opened quickly, indicating a lean condition or restricted main jet.
  • Fuel Overfilling: Gas is leaking out of the overflow tube while the vehicle is parked, signifying a stuck or worn internal float needle.
  • High Idle/Surging: The engine RPM hangs high or fluctuates wildly, typically caused by an air leak at the intake manifold or a worn throttle slide.
  • Spark Plug Fouling: The included spark plug shows heavy black soot, indicating the old carburetor was running too "rich" and wasting fuel.

Installation Tips

  • Check Your Clearance: Before installing the 38mm air filter, ensure you have enough frame clearance. If space is tight, you may need an angled foam filter or a 45-degree intake adapter.
  • The Gasket Sandwich: Ensure the insulating spacer (the thick plastic piece) is placed between the intake pipe and the cylinder head to prevent the fuel in the carburetor from boiling.
  • Cable Adjustment: After installing, ensure the throttle cable has 2–3mm of "play." If the cable is too tight, the engine will idle dangerously high as soon as it starts.
  • Mixture Tuning: Start with the air-fuel mixture screw at 1.5 to 2 turns out from fully seated. Adjust in 1/4 turn increments until the engine revs cleanly without hesitation.
  • Fuel Filter Direction: Ensure the arrow on the fuel filter points toward the carburetor. Always use a fresh tank of 91+ octane fuel to prevent immediate clogging of the new jets.

FAQs

This PZ22 22mm carburetor is commonly used on 4-stroke Chinese pit bikes, dirt bikes, mini bikes, ATVs, and quads in the 50cc, 70cc, 90cc, 110cc, and 125cc range, with 110cc-125cc being the most common fitment. Brands and model families mentioned for this style include SSR, TaoTao, Coolster, Apollo, RFZ, DB14, DB24, CRF50-style bikes, Sunl, Roketa, Buyang, Tank, NST, X-Pro, Coleman, Blazer, and Pitster Pro. Because these machines can vary by intake size, choke style, cable setup, and mounting dimensions, match your existing carburetor layout before ordering.
A PZ22 is most commonly selected for 110cc and 125cc 4-stroke engines. Some 70cc and certain 50cc applications can use it, but smaller engines are often fitted with a smaller carb such as a PZ19. If your machine already uses a PZ22 or has been modified for one, this kit is more likely to be a direct replacement. If you are upgrading from another carb size, verify intake diameter, air filter side connection, and throttle/choke configuration first.
Typical carburetor-related symptoms include hard starting, needing choke longer than normal, rough idle, hesitation on throttle, bogging under load, fuel overflow, poor acceleration, and black smoke or fuel smell from a rich condition. On small 4-stroke pit bikes and quads, these issues are often caused by varnish from old fuel, clogged pilot or main jets, dirt inside the float bowl, a sticking float needle, or incorrect air-fuel adjustment.
Installation is usually a moderate DIY job. On most pit bikes or ATVs, plan on about 30 to 60 minutes if access is straightforward. Common tools include screwdrivers, metric sockets or wrenches, pliers for hose clamps, and possibly an adjustable wrench for fuel line fittings or cable adjustment. Before installation, turn off the fuel, remove the old carburetor, compare the intake and airbox sides, and confirm the throttle cable and choke arrangement match your machine.
Usually yes. Even if it installs correctly, you may still need to set idle speed and fine-tune the idle mixture. It is also wise to inspect and clean the carburetor before installation, since small debris can sometimes be present, and to verify float height if the engine floods or starves for fuel. Final tuning depends on engine size, intake setup, exhaust, elevation, and fuel quality.
Check the intake manifold size, air filter connection size, choke type, throttle cable end, and fuel line routing. Also inspect the intake manifold gasket, fuel line, fuel filter, petcock, and air filter. A dirty tank or deteriorated fuel line can quickly contaminate a new carburetor. If the engine has been sitting, draining old fuel and cleaning the tank can prevent repeat clogging.
The primary identifier for this carburetor family is PZ22. Some listings also cross-reference certain Honda-style applications to 16100-GCF-672, particularly for specific XR70R, XR70, and CRF70F setups. That does not guarantee fit for every pit bike or ATV, so use cross-reference numbers only as a starting point and confirm your mounting style and controls against your original carburetor.
