RUITONDA PZ22 Carburetor for 110–125cc Pit Bikes & ATVs — 22mm Intake, Adjustable Idle

RUITONDA PZ22 is a direct-fit replacement carburetor engineered to restore throttle response and efficient fueling on small pit bikes, ATVs and go-karts that use a 22mm intake.

Designed as a compatible aftermarket option for a wide range of Chinese-made and Japanese-style small engines, this PZ22 carburetor fits many SSR, Coolster, TaoTao, Sunl and similar 110cc–125cc machines as well as CRF50/XR50 style bikes and some 70cc pit bikes. It gives a reliable fuel-air mixture, adjustable idle and choke features, and the common mounting dimensions needed for many swap or replacement jobs.

Will this RUITONDA PZ22 fit my bike or ATV?

It fits many 110cc–125cc SSR, TaoTao, Coolster and like-model engines, and is also compatible with Honda CRF50/XR50 style mounting systems used in aftermarket and Chinese copies. Confirm fit by checking the mount and intake measurements against your machine.

• Intake (outlet) diameter: 22 mm
• Bolting hole center distance (mount hole): 48 mm
• Air filter neck: fits 38–40 mm filters
• Commonly replaces OEM PZ22-type carbs on 70–125cc small engines

How does this carburetor affect engine starting and throttle?

Replacing a worn or clogged carb with a properly sized PZ22 typically improves cold starts, idle stability and throttle response. The unit includes idle and mixture adjustment features so you can tune the fuel delivery for your altitude and riding conditions.

• Adjustable idle screw for stable low-speed running
• Main jet and pilot jet accessible for tuning
• Simple choke lever for easier cold starts
• Standard 22mm venturi improves throttle reaction over smaller carbs

What should I know about installation and setup?

Installation is straightforward when the mounting pattern and intake size match your bike. Basic hand tools, a few clamps for the intake boot, and a short tuning session after installation are usually all that's needed. If you’re replacing a carb from a different type, expect to swap air filters, intake boots or throttle cable fittings.

• Requires matching 22 mm intake and 48 mm bolt spacing
• May need new intake boot or clamps (38–40 mm filter neck)
• Throttle cable attachment is standard for most small bikes/ATVs
• Perform jetting adjustments if altitude or performance needs differ

What materials and durability can I expect from this aftermarket carb?

The RUITONDA PZ22 is built with corrosion-resistant alloy components and a serviceable float bowl to withstand normal off-road and street use. Routine maintenance—cleaning jets and checking gaskets—keeps it operating reliably over time.

• Aluminum body for lightweight strength
• Serviceable float bowl for routine cleaning
• Replaceable jets and gaskets for long-term tuneability
• Designed for small-engine vibration and heat cycles

Who this is for: This carburetor is aimed at riders, DIY mechanics and small-vehicle repair shops that operate SSR, TaoTao, Coolster, Sunl, Pitster Pro, Coleman or Honda CRF50/XR50-style machines and need a cost-effective, replaceable PZ22 unit. Choose this RUITONDA PZ22 when your current carb is leaking, clogged or failing to deliver smooth idle and throttle response, and confirm the 22 mm intake and 48 mm bolt spacing before ordering.
