Temp Sensor
Here's a couple of tips I found I had a MM on my 01 RK and was lucky enough to find a tech that new what he was doing:
This is a very simple and effective way of adjusting your cold idle. If you start the engine stone cold and it idles below 1200 rpm (after it stabilizes) then turn the cold idle screw (in linkage, on the side that rotates with the throttle plates) in. If it's over 1300 rpm, then turn the screw out (therefore, set cold idle speed at 1200 rpm for TC-88's)It's that easy . Also, to guarantee that the idle will be recognized by the ECM, run the bike until it's fully warmed up, turn the hot idle (in the throttle body, forward of the front intake, near the bottom) up to 1200 rpm, shut off the ignition and pull the 5 amp fuse (in the fuse holder on the ECM bracket), run a lead from the cold (relay) side of the 5 amp socket to ground. Let it sit for 15 minutes or longer if practical, then put the fuse back in and warm it back up, turn it back down to 1000.
------------------------------------------------------------------------------------------------------------
2nd way of adjusting MM
Adjust the hot idle to 950/1050 rpm.
1. Unplug the temp sensor. Your bike now thinks it's cold!
2. Set the "cold idle" to 1500rpm
3. Shut the bike off.
4. Remove the 5 and 15 amp fuses from the fuse block which is on the side you took the cover off of.
5. Plug the cold sensor connector back in.
6. Replace the air cleaner assembly.
7. Wait at least 30 minutes, then replace the 2 fuses
When you restart your bike, the ECM should remember the new idle settings you did .
I have a 01 Touring Service manual if you're interested.

maybe try it both ways..if one sensor doesn't cure it try the other.
