BlueStars PZ22 Carburetor Kit 22mm for 50–125cc Dirt Bikes & ATVs — 38mm Filter, Right-Side Choke

BlueStars PZ22 Carburetor Kit is a complete 22mm replacement carburetor assembly with a 38mm air filter and fittings designed to fit many 50cc–125cc 4-stroke dirt bikes and ATVs.

If your small-displacement bike or quad is suffering from poor idling, hard starts, or inconsistent throttle response, the BlueStars PZ22 offers a direct-fit upgrade that restores proper air–fuel delivery. The kit includes the carburetor, intake pipe, air filter, fuel line and filters, clamps, gaskets and a spark plug so you get everything needed for a straightforward replacement. Built from aluminum alloy and paired with a conical high-density filter, this assembly aims to be durable and simplify installation for most applications that accept a 22mm intake bore.

Will this carburetor physically fit my dirt bike or ATV?

Compatibility depends on your engine's intake bore, mounting hole spacing and choke orientation. The PZ22 has a 22mm inner diameter and a bolt hole center-to-center distance of 48mm, with the hand choke located on the right side. Confirm these measurements against your original equipment before purchasing.

• Intake inner diameter: 22mm
• Mounting hole center-to-center: 48mm
• Air filter outer diameter: 38mm
• Hand choke positioned on the right side

How will the BlueStars PZ22 affect engine performance and reliability?

A properly matched carburetor helps establish the correct air-to-fuel ratio, improving starting, throttle response and idle stability. This kit’s precision-machined carb body plus the supplied filter and fittings help reduce common issues like flooding, misfires and rough idling when installed and tuned correctly. It won’t change engine displacement, but it can make the engine operate closer to the intended factory parameters.

• Restores consistent fuel delivery for smoother idling
• Reduces chance of flooding and hard starts with proper jetting
• High-density filter keeps particles out of the intake tract
• Includes fuel filters to protect small engine components

What is included in the kit and what quality features should I expect?

The package supplies every basic part needed to replace a stock carburetor: the PZ22 carb itself, intake pipe, 38mm conical air filter, fuel line and two fuel filters, several clamps, a gasket set and a replacement spark plug. The carburetor is made from a lightweight aluminum alloy for corrosion resistance and strength, and the air filter uses a double steel mesh for improved particle protection.
