As per the factory specs, it can idle it up to over 2000 on really cold mornings. If you really want to adjust it, there's a screw waaaaay down on the bottom of all the linkages tucked away that you can barely see/get to that adjusts the fast idle. Maybe someone can post a pic, cause I don't have one.
