LIAMTU PZ22 ATV Carburetor Replacement 22mm Intake with 38mm Air Filter & Fuel Filter for 110–125cc Pit Bikes and Go-Karts

LIAMTU's PZ22 carburetor kit is a direct-fit replacement carburetor with a 22mm intake, cable choke, included fuel filter, and a 38mm air filter designed for 110cc–125cc pit bikes, ATVs and go-karts.

This compact carburetor assembly combines an intake mount diameter of 22mm, a 48mm bolt spacing, and an attached 38mm air filter to restore fuel delivery and throttle response on small-displacement off-road machines. It ships with a fuel filter and cable-style choke for easier installation and routine maintenance. The unit is compatible with many SSR, CRF50-style, Predator, Sunl and Taotao models that use PZ22-style carbs, but measuring the mount and bolt holes first will ensure proper fit.

Will this carburetor fit my 110cc or 125cc bike or ATV?

Most small-displacement pit bikes and ATVs that originally use PZ22 carburetors will accommodate this LIAMTU replacement. The critical dimensions are the 22mm intake mount and the 48mm bolt-hole spacing so you can match the unit to your engine’s intake manifold.

• Intake mount diameter: 22mm (PZ22 standard)
• Bolting hole distance: 48mm for secure mounting
• Air filter outer diameter: 38mm for filter boot fitment
• Common fits: many 110cc–125cc SSR, CRF50-style, Predator, Sunl, Taotao pit bikes and go-karts

How easy is it to install and what tools are needed?

Installation is straightforward and does not require specialized shop equipment. The PZ22 carburetor uses a cable choke and standard mounting holes, so basic hand tools and a few clamps are usually all that's required.

• Tools: screwdriver set, pliers, socket or wrench for mounting bolts
• Time: typically under one hour for a simple swap
• Included accessories: fuel filter and 38mm air filter to simplify reassembly
• Tip: verify vacuum/vent hoses and throttle cable routing before final tightening

What performance or maintenance benefits does this kit provide?

Replacing a worn or clogged carburetor can improve throttle response, starting reliability and fuel metering compared with a damaged factory unit. The included fuel filter helps prevent debris from entering the carburetor, while the air filter helps protect internal passages from dirt and dust.

• Cleaner fuel flow thanks to the supplied inline fuel filter
• Restored throttle feel via the cable choke and fresh throttle bore
• Improved longevity by preventing grit and dust from entering the engine
• Simple tuning access for pilot and main jets if adjustments are needed

Are there any measurements or checks I should do before ordering?

Measure your current carburetor’s intake opening and bolt spacing to confirm compatibility. If the dimensions don’t match exactly, mounting adapters or manifold differences may be needed. When in doubt, contact the seller with model and photo details.

• Measure intake mount diameter: confirm 22mm fit
• Check bolting hole distance: 48mm center-to-center
• Verify air filter boot acceptance for 38mm filter diameter
• If unsure, message the seller with your bike model and pictures
