BlueStars PZ22 22mm Carburetor Kit for 50–125cc Dirt Bikes — 38mm Air Filter & Hardware

BlueStars PZ22 Carburetor Kit is a 22mm replacement carb with a 38mm air filter and complete installation hardware designed to fit many 50cc–125cc 4-stroke dirt bikes, quads and ATVs.

If your small-engine ride is struggling with cold starts, rough idling, or inconsistent throttle response, a correct-size carburetor and air intake can restore reliable performance. This kit supplies the PZ22 carb body (hand choke on the right), a conical 38mm air filter, intake pipe, fuel line and filters, clamps, gaskets and a spare spark plug — everything needed for a direct swap on compatible machines. The main dimensions to check are a 22mm intake inner diameter, 48mm bolt center spacing, and 38mm air-filter outer diameter.

How will this carburetor affect starting and idling?

Installing a properly sized carburetor can make cold starts easier and smooth out idle speed by providing the correct air–fuel mixture for your engine. The hand choke on the right side helps with enrichment during startup without complicated adjustments.

• Right-side hand choke for simpler cold starts
• PZ22 22mm bore tuned for small four-stroke engines
• Factory-set jets for balanced idle and initial throttle
• Included gaskets and clamps reduce leaks that cause poor idling

Will this kit fit my bike or quad?

Compatibility depends on your machine’s intake diameter and mounting bolt spacing. This kit is intended for many 50cc, 70cc, 110cc and 125cc dirt bikes, ATVs and quads with 4-stroke engines that accept a PZ22-style carb and have the choke on the right.

• Intake inner diameter: 22mm
• Mounting bolt center-to-center: 48mm
• Air filter outer diameter: 38mm (conical style)
• Common fitment: SSR, TaoTao, Coolster, Apollo, RFZ, Blazer, X-Pro, Coleman, PitsterPro

What parts are included and why they matter?

This kit is sold as a full replacement package to simplify installation and reduce additional purchases. The included components let you replace the carb and refresh the air and fuel delivery path simultaneously, preventing common issues caused by degraded or mismatched parts.

• PZ22 carburetor with hand choke on the right for enrichment control

How durable and serviceable is the BlueStars PZ22?

The carburetor body is machined from lightweight aluminum alloy for corrosion resistance and strength, while the air filter uses a dual steel mesh to trap dirt effectively. Routine maintenance is straightforward: clean the filter and inspect gaskets, jets and hoses; the kit’s spare components make on-the-spot fixes easier.

• Aluminum alloy body resists corrosion and keeps weight low
• High-density mesh air filter reduces particulate ingestion
• Replaceable fuel filters and hoses included for maintenance
• Lifetime protection covers defects as provided by the brand

It’s a practical option if you need to solve starting problems, poor idle, fuel leakage or want to replace a worn carburetor with appropriately sized hardware. Before ordering, double-check your original part’s bore size, bolt spacing and choke position to ensure a correct fit and avoid returns.
