Industrial 14-1057 Needle And Seat Valve For Carburetor

The WPS 14-1057 needle and seat valve is a precision carburetor internal component that regulates fuel flow into the float bowl of Mikuni carburetors used on powersports machines, and it carries clear brand and part-number identifiers for straightforward replacement in Mikuni VM28/163-2.0–based assemblies. As a float needle and seat assembly, it meters fuel to the float bowl and provides float bowl shutoff to help prevent overflow and maintain proper engine response, throttle smoothness, consistent fuel metering, and predictable throttle response. The part is intended for carburetor rebuilding and fuel system maintenance and is commonly installed on motorcycles, ATVs, snowmobiles, and off-road recreational vehicles that rely on Mikuni carburetors for accurate metering, and it aligns with Mikuni VM28/163-2.0 configurations across powersports platforms. OEM reference VM28/163-2.0; common replacements include Mikuni VM28/163-2.0, K&L Supply Carburetor Needle Valve Kit, and All Balls Carburetor Needle and Seat Kit to support standard Mikuni float valve service.
