Marelli hot idle problem

2001 RK ,Dobeck TFI,SE211 cams,fullsac duals,Ness Big Sucker. What would cause the hot idle to all of the sudden drop to almost nothing? I have to add throttle just to keep it running. When it will idle by itself it sounds really good! Almost like a carbed motor,but it needs to be higher than that. I know there are posts on how to set the idle,but what makes it change?
