Re: Setting hot idle for 2000 harley davidson flhtcu-i....
Idle speed on a fuel injected bike must me set by the dealer if it's still stock. I think you can set it yourself in you have a Power Commander on the bike but I don't know how to work with that unit.

If your bike is stalling out when the engine is cold, this is typical of a carburetor equipped engine. You need to run a little longer with your enricher on. After it warms up, if it's still stalling out, remove the outer air filter cover and look at the upper right of your carb. There is a screw there. This is the throttle stop screw. Turn it clockwise to increase the idle speed. Set the idle speed when the engine is at full operating temp.
If you bike is equipped with a carburetor, the idle stop screw is located at the top of the carb on the right side. Counterclockwise turn slows the idle speed.
If you bike is fuel injected, a dealer or shop will have to set the idle speed electronically.
the only way to check the oil pressure switch is to remove it and replace it, or test with a analog guage, if the pressure at idle is 5psi or higher at idle just replace the switch, the switch is not real percise and harleys have a dry sump oil system, and the pump is a g-rotor style dry sump pump at idle the engine might have 5-15lbs of pressure when warm and higher with engine revs you didnt say what weight oil you are running it could be to light of a viscosity 10-50, use a heaver weight oil 20-50 or like i use in my bike (2002 FLHTCU w/sidecar) straight 60wt hopes this helps
