YOXUFA PZ22 22mm Carburetor Replacement for 50–125cc Pit Bikes & ATVs — Left-Choke, Includes Filter & Hardware

The YOXUFA PZ22 is a 22mm replacement carburetor designed to restore reliable fuel delivery and throttle response on 50–125cc four-stroke pit bikes, ATVs and quads.

If your bike or quad is running rough, stalling at idle, or suffering poor throttle response, a worn or clogged carburetor is often the cause. This YOXUFA PZ22 unit offers a direct-fit alternative for many small-displacement Chinese and Japanese-style machines, supplied with mounting hardware, fuel fittings and a small red foam air filter to simplify installation and get you back on the trail faster.

Will this carburetor fit my bike or ATV?

This PZ22 is built for a broad range of small four-stroke engines. It’s intended for models that use a 22mm intake bore and share the same mounting geometry, notably many SSR, TaoTao, Coolster, Apollo and other 50–125cc machines.

• Intake bore: 22mm (inside diameter)
• Bolt-to-bolt mounting: 48mm center-to-center
• Compatible models listed include SSR 110/125, CRF50F, XR50, TaoTao DB14/DB24 and similar

What exactly comes in the box and what will I need?

The package includes the carburetor assembled with a left-side hand choke, plus multiple consumables and clamps so you can complete the swap without sourcing small parts. You may still want basic hand tools and carb cleaner for prep and tuning after installation.

• 1 x YOXUFA PZ22 carburetor (left-side choke)
• 1 x red foam air filter, 1 x red fuel line, 2 x inline fuel filters
• 4 x hose clamps, gasket set, and 1 x spark plug

How will installing this carburetor change performance and maintenance?

Replacing an old carburetor with a fresh PZ22 typically restores smoother idling, quicker throttle response and easier starting. You should tune idle and mixture screws to match your specific engine and altitude — the included hardware gets you running, but fine adjustments improve reliability and fuel economy.

• Expect improved idle stability and crisper throttle transitions
• Requires basic tuning of idle and mixture screws after fitment
• Periodic cleaning of jets and filter recommended to maintain performance

Are there any installation notes or compatibility warnings?

Note that this unit features a left-side choke lever; confirm that orientation works with your frame and cable routing before purchase. Verify bolt spacing and intake diameter against your old carb to ensure a true bolt-on replacement.

• Choke lever: left-hand mount — confirm cable routing compatibility
• Air filter inner diameter: 38mm — check filter or intake boot match
• Some models may need throttle cable or intake adapter adjustments

Who this is for: Riders, mechanics and hobbyists who own small-displacement four-stroke pit bikes, quads or ATVs and need a reliable, affordable carburetor swap. It’s especially suitable for owners of SSR, TaoTao, Coolster, Apollo, Coleman and similar machines that accept a 22mm PZ series carburetor and who want a ready-to-install kit with filters, clamps and a spare spark plug.
