LEIMO KPARTS PZ20 Carburetor for 50–125cc ATVs & Dirt Bikes — 20mm Intake, 35mm Conical Air Filter

The LEIMO KPARTS PZ20 carburetor is a direct-fit replacement carburetor kit with a 35mm conical air filter designed to restore smooth fuel delivery on 50–125cc four-stroke ATVs, go-karts and small dirt bikes.

This PZ20 assembly is engineered as a durable, OEM-standard replacement for worn or damaged carburetors on many Chinese-brand and compatible small engines. Machined from quality materials and supplied with a double steel-mesh 35mm conical air filter, the kit aims to simplify installation and improve throttle response on machines that use a 20mm intake and a 48mm mounting spacing.

Will this carburetor fit my ATV, go-kart, or dirt bike?

Compatibility is based on intake diameter, mounting center distance and engine type. The PZ20 suits most under-125cc four-stroke single-cylinder engines that match the listed dimensions and throttle/venturi layout.

• Intake inner diameter (mounting side): 20mm
• Mounting center-to-center: 48mm
• Air filter outer diameter (filter side): 32mm with a 35mm conical filter supplied
• Known fits: TaoTao, SunL, Kazuma, Buyang, Lifan, Honda CRF50F/CRF80F series and similar models

How easy is installation and what comes in the kit?

The PZ20 kit is intended for straightforward swap-outs when replacing like-for-like carburetors. Basic hand tools are typically all that’s required; some machines may need small hose clamps or a throttle cable adjustment for a perfect fit.

• PZ20 carburetor body and float bowl
• 35mm conical air filter with double steel mesh
• Standard jets and needle components for tuning
• Gaskets and hardware to match common 48mm center mounts

What performance or maintenance changes should I expect?

Replacing an old, clogged, or leaking carburetor with this PZ20 can restore consistent idling and throttle response. The included conical air filter helps keep debris out while the double mesh improves longevity compared with a single-layer foam filter.

• Improved throttle response after correct jetting and sync
• Smoother idle and easier cold starts on most compatible bikes and ATVs
• Filter maintenance: clean and inspect mesh regularly to retain flow
• Minor jet or needle adjustments may be needed for altitude or fuel variations

Who is this for: This PZ20 carburetor kit is aimed at DIY mechanics, repair shops and owners of small four-stroke ATVs, quads, go-karts and dirt bikes under 125cc who need a reliable replacement or upgrade. It’s especially useful if your machine uses a 20mm intake with a 48mm mount and you want a ready-to-install carburetor complete with a durable 35mm conical air filter. If you’re uncertain about fitment, measure your intake bore and mounting centers or consult vehicle-specific parts lists before purchasing.
