RedCap PZ22 22mm Carburetor for 110–125cc ATVs & Pit Bikes — 38mm Filter, Cable Choke, Adjustable Mixture

This aftermarket carburetor replaces worn or smaller PZ19 units and gives you adjustable air/fuel mixture and idle speed for easier tuning and improved throttle response on compatible bikes and quads. Built with a left-side idle and a 48mm bolt-to-bolt spacing, the PZ22 is intended for a broad range of SSR, Apollo, Taotao, Roketa, Sunl and other common clone models. Always compare your current carburetor to the photos and specs before ordering to ensure fitment.

Will this carb fit my 110cc or 125cc ATV or pit bike?

Fitment is common across many Chinese-made 110cc–125cc engines, but not universal. Check the bolt spacing, filter size and mounting style to confirm compatibility.

• Carburetor bore: 22mm (PZ22)
• Filter connection outside diameter: 38mm
• Idle (throttle stop) located on the left side
• Side-to-side bolt spacing (hole-to-hole): 48mm

How does the PZ22 improve performance compared with a PZ19?

The larger 22mm throat can deliver more airflow and fuel at higher throttle openings, which helps engines breathe better under load. That can translate into smoother acceleration and fewer signs of restriction on modestly tuned 110–125cc motors.

• Increased bore size over PZ19 for better midrange power
• Adjustable air/fuel mixture for fine tuning performance
• Cable choke for reliable cold starts and consistent operation
• Accessible float bowl for easier maintenance and cleaning

What mounting and adjustment features should I expect?

This carb mounts via a spigot with a side bolting pattern and includes user-accessible adjustment points for both idle and mixture. It’s designed to be a direct-replacement shape for many clone-engine installations, but some setups might need a new intake or adapter boot.

• Mount type: spigot with side bolting
• Idle adjustment: left-side screw for quick tuning
• Mixture screw: external air/fuel tuning capability
• Float bowl: removable for cleaning and servicing

Who is this for? The RedCap PZ22 carburetor is aimed at riders, mechanics and hobbyists who maintain or upgrade Chinese-clone 110cc–125cc ATVs, pit bikes, and quads. If your machine currently uses a PZ19 and you want slightly more airflow or if your original carburetor is leaky, clogged or damaged, this PZ22 is a straightforward replacement option. Before buying, photograph your existing carb and compare the mounting style, bolt spacing and filter diameter to ensure this unit matches your machine. If you’re uncertain, contact the seller with a clear image of your original carburetor for confirmation.
