PE22 Carburetor with 48mm Air Filter Kit - Better Throttle Response

Our review of the PE22 Carburetor with 48mm air filters kit finds it best suited for riders who want a straightforward upgrade for small-displacement dirt bikes and pit bikes. The bottom line: this carburetor delivers noticeable improvements in throttle response and midrange power when swapped in for a worn or restrictive PZ24 unit, and it comes with the basic jets and a 48mm air filter needed to get running quickly. Installation is simple for anyone comfortable with basic engine work, and customers report solid fitment on popular 125cc to 140cc machines.

Key Features

• Compatibility: Fits a wide range of dirt bikes, ATVs, go karts, mopeds and scooters, making it a versatile spare or upgrade for many small engines.
• Replacement option: Intended as an upgrade path for engines using a PZ24 carburetor, providing owners an easy swap to improve performance.
• Mounting size: The flange hole spacing is 48mm and the engine side inner diameter is 24mm, so it matches common intake manifolds for the target engines.
• Included hardware: Ships with a 48mm air filter, one slow jet and three main jets so the user can tune for better fuel/air mixture without sourcing extra parts.
• Improved performance: Designed to deliver a more precise fuel and air mix to improve acceleration, low-end roll and throttle response on small-displacement bikes.

Who It's For

This carburetor is aimed at owners of 125cc to 140cc dirt bikes, pit bikes and similar small engines who need a direct-replacement or want an easy performance upgrade. Riders with machines from brands like Apollo, TaoTao, Lifan, Kayo, SSR and many common imports will find the PE22 fits and bolts up with minimal modification in most cases.

It is not ideal for someone who cannot measure flange spacing or confirm a 24mm inner diameter; a mismatch will require manifold adapters or a different carb model. Also, riders needing a fully jetting-specific race setup should be prepared to do further tuning beyond the included jets.

Pros & Cons

Pros

• Easy to install for those familiar with carb swaps, often bolting on without modification.

• Good value for the price compared with buying a replacement carb and parts separately.

Cons

• Requires verification of the 48mm flange and 24mm bore dimensions before purchase to ensure fitment.
• May need additional jetting or tuning for optimal performance on some machines.
