Snowdevil,
You mentioned that you are running in prime -- have you done the rest of the items recommended by Serobot ....
there are some tubes and nipples that need to be plugged off.

If your idle increase is relatively minor, that could be due to your engine warming up
(the oil thins out a tiny bit when it gets hot, especially if you are using a heavy 20w50 oil)
My idle increases a bit after a hard ride, everything is hot, fully expanded and worked in well after that hard ride.
When the engine is cold, it's cold after all. It should have a small difference in idle speed between cold and freshly exercised hot.
