All Balls Carburettor Rebuild Kit For Yamaha YZ125 YZ125X - 26-10158

This kit is designed for Yamaha YZ125 models from 2022-2025 and Yamaha YZ125X models from 2023-2025.

No, this kit contains components to rebuild *one* carburetor. If your ATV has dual carburetors, you will need to purchase two kits.

You will generally need screwdrivers (flathead and Phillips), a socket or wrench set, pliers, carburetor cleaner spray, compressed air, and potentially a specialized carburetor synchronization tool if your model requires it.

Typically, the kit includes the correct jets for the specified application, so rejetting is usually not required unless you have made other engine modifications.

With proper installation and maintenance, a rebuilt carburetor using quality parts like those from All Balls can last for many riding seasons, restoring its original performance.

Please refer to the retailer or All Balls Racing's official warranty policy for specific details on product coverage and duration.

This kit is specifically engineered for the Yamaha YZ125 and YZ125X models listed. Using it on incompatible models may lead to improper fitment and performance issues.

Ensure the float level is set correctly, check that the correct size jets are installed, and verify the choke is not stuck partially closed.

Check for air leaks around the carburetor intake and manifold, verify the float level is not too low, and ensure all jets are clear and correctly sized.

Confirm fuel supply, check for spark, ensure the carburetor is correctly reassembled with all parts in place, and verify the choke is functioning properly.

Clean the idle circuit jets, adjust the idle speed screw, and check for vacuum leaks. Ensure the air/fuel mixture screw is set correctly.
