CB1100 Idle speed instability problem

[dave]

My bike also sounds normal.

Most recently I've been having the high-idle issue (1500+ rpms). The mechanic at dealership believes replacing the EOT Sensor may fix the problem. I'm heading down the dealership tomorrow so they can replace the part.

Unplugging the EOT sensor will cure the problem, but then your "check engine" light and the engine temperature light will both be on. I replaced my EOT sensor and it did not cure the problem. BTY - it's a simple, 10 minute job to do it yourself.
