Dynojet Research Exhaust Servo Eliminator Module - Yamaha - ESRM-1

Eliminates the need for a heavy, bulky, exhaust servo motor and cable assembly when installing full exhaust systems on late Yamaha models. Keeps the fuel injection light from coming on unless there is a "real" problem with the bike's systems. Decreases the weight of the bike and adds space for additional components. Made in the USA.
