When adding a full exhaust system to late model Yamaha motorcycles you no longer need the heavy, bulky, exhaust servo motor and cable assembly.
The problem is if you just unplug the servo motor from the bike it triggers the FI light on the dashboard. This is not only annoying, but it keeps you from knowing if there is another "real" problem with the bikes' systems.
By installing the small, lightweight, ESRM-1 you will keep the FI light from coming on and it will also turn it off if you have already removed the servo and triggered the light. Additionally, you will decrease weight and increase space on the bike for the installation of other equipment.

Unless there is a real problem with the bikes system, this keeps the FI light from coming on.
