THis " problem" has componants of both high and low idle, therefore I think its some kind of sensor problem, but I am not an engineer.
May not be the issue...but want to check as many possibilities as possible
Small leak = high idle
Big leak = engine dying
BTW, in the Hunting RPM thread, post 72, popgun posted the EOT resistance value
"From the manual: STANDARD: 2.4-2.9 Kohms (20 degrees C/68 degrees F)"
Surprised that it is not a chart with temperature ranges.

But if it were vacuum leak related, wouldn't the high idle happen consistently, as in "all the time"? I've had high and low idle on the same ride. Stop, turn off engine, restart, problem goes away, sometimes it doesn't.
jdvalero pulled the [url=http://cb1100forum.com/forum/showthread.php?tid=10073&pid=187944#pid187944]TPS sensor plug and found a physical issue with wiring and says that this has fixed the issue for him. I hope that the problem truly is fixed for him, because that would be one of the few cases where something concrete was spotted as being "faulty", a fix applied, and idle issue goes away.
Per suggestions near that post, I pulled that plug, cleaned connectors and applied a tiny bit of dialectic grease, reconnected. I've done 3 rides since...1st time with bike fully warm, 1 instance of low idle at 750rpm. Tuned off bike, started and idle returned to normal. Last two rides of 1/2 hour to 1 hr, no issues at all. Fixed? Hahahaaaa. Yes, until it isn't.
