The All Balls Carburetor Repair Kit, manufacturer part number 26-1387 and vendor part number 26-1387, provides the necessary components to rebuild and repair the carburetor on select Yamaha ATV models. This kit fits the 2007 and 2008 Yamaha YFM400FG Grizzly 4WD with independent rear suspension (IRS). Components are based on United States model specifications, so discretion is recommended when installing the kit on non-U.S. models.
The kit includes all required O-rings, gaskets, jets, a needle, mixture screw, float bowl screws, float valve needle, and float valve seat. OEM jet sizes are included to help support proper carburetor function and simplify the repair process. NBR rubber is used for the O-rings and rubber gaskets, providing excellent 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.
Designed for off-road use only, the All Balls 26-1387 Carburetor Repair Kit is suitable for servicing the original carburetor on compatible Yamaha YFM400FG Grizzly 4WD IRS models. Confirm the vehicle model, year, carburetor configuration, and regional specifications before installation to ensure proper fitment.
