Mikuni Bs26 Carburetor

The Mikuni BS26 is a constant velocity (CV) carburetor widely utilized in small to mid-displacement motorcycle engines, typically ranging from 150cc to 250cc. Manufactured by Mikuni Corporation, the BS26 is renowned for its fuel efficiency, smooth throttle response, and reliability. Unlike older "slide needle" carburetors, the BS26 utilizes a diaphragm-controlled vacuum slide, allowing the engine to demand the precise amount of air-fuel mixture required for current riding conditions.
