PWK-style 24 mm carburetor kit for select 50cc–125cc two-stroke and four-stroke dirt bikes, pit bikes, mini bikes, ATVs, quads and scooters. This is a universal-style performance component; engine displacement alone does not confirm fitment.

• Manifold-side outer diameter: 35 mm
• Air-filter-side outer diameter: 50 mm

Reference applications

Intended for compatible 50cc–125cc motorcycle and powersports engines using the listed spigot dimensions and a matching cable, choke and fuel arrangement. Verify whether your application is two-stroke or four-stroke and whether tuning parts are appropriate for the engine.

Package contents

• 1 PWK-style 24 mm carburetor
• 1 air filter
• 3 fuel-line sections
• 3 additional jets
• 1PZ branded packaging

Verify before ordering

• Measure the engine-side intake connection and air-filter connection.
• Confirm overall length and available frame clearance.
• Compare throttle-cable end, cap thread and slide travel.
• Confirm choke type and accessibility.
• Confirm fuel-inlet and vent/overflow routing.
• Check whether an intake adapter or manifold is required.

Tuning and installation

Jetting may require adjustment for engine design, intake, exhaust, altitude and climate. The included jets are not a guarantee of correct calibration for every application. Begin with the engine manufacturer’s specification where available, eliminate intake leaks and make tuning changes carefully.

Disconnect the spark-plug lead and turn off the fuel before service. Confirm the throttle returns fully, route hoses safely and check for leaks before starting.

For fitment help, contact 1PZ Support with the engine/equipment model, two-stroke or four-stroke configuration, original carburetor photos, cable details and measured connection diameters.
