The IAC controls idle speed, but it has other input to base idle control on and VSS is just one.
If you have a vacuum leak, ifanyone has adjusted the throttle plate/idle set screw. If any modifications/changes have been made this could cause idle control issues.
Throttle plate coking (buildup behind the plate) will cause idle control changes. The ECM has no idle adaptation for this type of problem like automotive PCM`s do.
You could have coking on the IAC tip and in the IAC idle air passage too. All this stuff can cause loss of idle control within the set parameters.

I know the speed sensor handles: idling, turn signal cancellation, cruise control(don't have), and speedometer. but all these seem fine....

I havent done any work on the bike prior to the light coming on

You should clean the throttle body, IAC valve and air passage for starters. I have no idea how you could clear the codes without a SERT or other tuner module.

what is the IAC valve?

no one has made any adjustments.....how do I check for these build ups

Buy some induction system cleaner and run it through the IAC passage with a hot motor. This will decarbon the passage and the IAC valve pintle tip.
I`m not claiming this will fix your problem, but it`s the starting point for proper IAC valve control. Do you have atuning(SERT/PCIII -ETC) box with software so you can look at real-time data.

well now that I think about it the only thing I did in the last 5000 miles is about 2 weeks ago I lubed the throtle cables

Remove the air filter and open the throttle plate. Look at the throttle body bore. Clean it out with B-12 carb cleaner and a rag.

You have an idle control issue and you need to get real-time data values on the IAC at idle. TPSspecs should be inspected as well.

when you say
"run it through the IAC passage with a hot motor"
do you mean while running?
