RedCap PZ22 22mm Carburetor for 110–125cc Pit Bikes ATV — 38mm Intake, Cable Choke

This carburetor is built as a direct-fit upgrade for common small-displacement engines found on Apollo, SSR, Roketa, Taotao, Sunl and similar 110cc–125cc models. It replaces many older PZ19 or worn stock carbs to restore throttle response, enable tuning of idle and air/fuel mixture, and make bowl access simpler for routine maintenance. Before ordering, compare your original carburetor to the measured specs to ensure compatibility.

Will this PZ22 carburetor fit my bike or ATV?

Compatibility depends on your machine's intake diameter, mounting spacing and choke style. This unit is intended for left-idle, spigot-mounted engines with a 38mm filter flange and 48mm bolt-hole spacing. If your original carburetor matches these measurements it is likely to fit; otherwise adaptors or a different model may be required.

• Carb size: 22mm venturi for small-displacement 110–125cc engines
• Filter flange: 38mm intake to accept common foam or cone filters
• Mounting: spigot-style with 48mm hole-to-hole bolt spacing
• Choke: cable-operated for standard throttle/choke controls

How does this carburetor improve performance and maintenance?

Upgrading from a smaller or worn carburetor can produce crisper throttle response and easier tuning. The PZ22 allows adjustment of the pilot and main circuits plus the idle speed, so you can optimize fuel delivery across the rev range. The bowl is designed for straightforward access, simplifying cleaning and needle jet replacement.

• Adjustable air/fuel mixture and idle for better throttle control
• 22mm bore balances torque and top-end for 110–125cc engines
• User-friendly bowl access for routine cleaning and servicing
• Cable choke integrates with most stock control assemblies

What are the technical specifications I should check before buying?

Measure your current carburetor and mounting arrangement to confirm a match. Key dimensions include the carb bore, intake/filter flange, bolt-hole spacing and the choke type. Also inspect whether your engine expects a left-sided idle location and whether a spigot mount is used.

• Bore: 22mm (PZ22)
• Filter side diameter: 38mm
• Hole-to-hole bolt spacing: 48mm
• Idle location: left; mount type: spigot; choke: cable

Can I install this carburetor myself, and what else might I need?

Many mechanically inclined riders can fit this carburetor with basic tools, but proper setup requires time for jetting and syncing to your engine. You may need replacement gaskets, intake clamps, or a compatible air filter. If your bike originally used a different flange size or mounting method, an adapter or bracket may be necessary.

• Typical install tools: screwdrivers, pliers, socket set, hose clamps
• Recommended extras: intake gaskets and a 38mm-compatible air filter
• Expect to fine-tune jets and idle after installation
• Contact seller with photos if you’re unsure about compatibility

Who is this for: The RedCap PZ22 is aimed at riders and mechanics who run 110cc–125cc Chinese-clone dirt bikes, pit bikes and ATVs—brands such as Apollo, SSR, Roketa, Taotao, Sunl, Coolster, ThumpStar and similar models. It’s well suited for owners replacing a worn PZ19 or stock carburetor who want improved throttle response and easier servicing. If you need precise fitment help, provide a photo of your existing carburetor and the intake measurements to confirm compatibility before purchase.
