1PZ PWK 24mm Carburetor Kit for 50cc-125cc Dirt Bike and ATV

Spec: PWK 24mm racing-style carb kit - intended for about 50-125cc 2T/4T; confirm spigot OD, jetting and cable before install.

Hero size check: PWK-style 24 mm carburetor — manifold ID 24 mm · manifold OD 35 mm · air-filter OD 50 mm. Measure your intake before you buy.

Performance carburetor kit for select 50cc–125cc two-stroke and four-stroke dirt bikes, pit bikes, mini bikes, ATVs, quads and scooters that match these spigot dimensions. This is not a guaranteed “fits all” universal part—displacement alone does not confirm fitment.

Critical dimensions (measure these)

• Manifold-side inner diameter: 24 mm
• Manifold-side outer diameter: 35 mm
• Air-filter-side outer diameter: 50 mm

Likely exclusions / when NOT to order

• Engines with a different manifold ID/OD or air-filter OD
• Applications that need a different choke style, cable end or overall length
• OEM-only setups that require a factory matched carburetor without adapters
• “Universal 50–125cc” shopping ads that did not verify the three dimensions above

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.
