QuadBoss 00-04 Yamaha YFM400 Big Bear 2x4 Carburetor Kit

This QuadBoss carburetor kit is built with nitrile rubber for all O-rings and rubber gaskets, ensuring a solid seal. If your Yamaha YFM400 Big Bear's carburetor is acting up, this kit has everything you need to get it running right again. It includes all the small parts that often wear out, like O-rings, gaskets, jets, needle, mixture screw, float bowl screws, and the float valve needle and seat.

The kit uses high-performance interface gasket material for any paper gasket applications, and it comes with O.E.M. jet sizes. This means you're getting parts that match the original specifications for your Big Bear, making the repair straightforward. If your model has two carburetors, this kit contains the components to fix both of them.

Keep in mind that this kit is based on U.S. models, so use discretion if your ATV is from outside the U.S. Also, this kit is not CARB approved and cannot be shipped to California.
