Funny you should mention, although mine was the opposite. My bike no longer had much of a fast idle, usually around 14-1500 rpm. Following the instructions in the factory manual, it states to adjust the fast idle cam screw to obtain a reading of 1.3 volts at the TPS. No matter where turned the screw, I would see 4.8 volts. This was with a stone cold engine and double/triple checking the instructions.
I ended up just turning the screw to obtain the 2000 rpm specified and calling it a day. It seems to function well, the idle settles down to 1200 within a few moments.
I did find that if you remove the left fairing panel, hold the throttle wide open, you can (if ur hands are small, and using an extreme short phillips screw driver) you can get at the screw to adjust the fast idle speed. I am still curious however, why I could not change the voltage reading.
Upon inspection, there was noticable wear on the fast idle cam and roller, enough to decrease the fast idle speed considerably. Note that my engine has been started a zillion times, therefore the wear.
I also checked my TPS, using dealer mode. All was well. As I did not have a security torx bit, I removed one screw at a time with a small needle-nose vice grip and cut a slot in the screw heads in order to use a slotted screw driver in the event adjustment was required.
