Restore reliable carburetor performance with the All Balls Carburetor Repair Kit, manufacturer part number 26-1388 and vendor part number 26-1388. This repair kit is designed for select Yamaha YFM400 Big Bear models, including 2WD and 4WD configurations from 2000 through 2006. It includes the components needed to service and rebuild the carburetor using OEM-based jet sizing.
Built for practical fuel-system maintenance, the kit includes O-rings, gaskets, jets, a needle, mixture screw, float bowl screws, float valve needle, and seat. NBR rubber is used for the O-rings and rubber gaskets, providing resistance to ethanol commonly found in today’s fuels. Applications originally equipped with paper float bowl gaskets are upgraded with High Performance Interface Gasket material for dependable sealing.
Fitment is based on U.S. models, so verify the carburetor configuration before installation on non-U.S. versions. This All Balls kit fits the following applications: 2000–2006 Yamaha YFM400FB Big Bear 4WD [SRA] and 2000–2002 Yamaha YFM400 Big Bear 2WD [SRA]. The kit is intended for off-road use only.
