Thanks, but that is exactly what is happening. I pulled the middle and lower cowl off today; I am getting good at it; and checked to make sure I had the right know sensor (black wire) connected properly and it was connected. Did the rpm test again twice and the same thing happened.. When the FI light came on, the R's dropped more than 2000 RPM. Never did that when I had the FI light come on while riding, couldn't really tell any difference in performance or fuel economy while riding with the light on.... I have checked all the knock sensor wiring all the way to the ECM on the right side and it has continuity. I am going to pull the middle cowl on the left side and check that wiring tomorrow.. I have an ECM (used) on the way from a 2003 that should be here on Monday. I will install it and see if I have the same problem.
I am curious... The corrections to the service manual state that the code 25 and 26 are reversed.. Meaning that the code 26 is the left knock sensor rather than the right that the service manual states. Is that correct or not?
