surging idle
My 07 street bob has been surging at idle alot after it's warmed up. I am running V&H Big Radius 2:1 with a high flow air cleaner and a V&H fuelpak set at the appropriate setting for the pipe. It seems a little rich due to the black soot build up in the outlet of the pipe and lately it has been surging occassionally as well as when coming to a stop it starts idling really low as if it's about to stall out. I have cleaned the air filter and the Idle Air Control motor circuit vacuum ports to make sure they were free from dirt and particulate build up and I have been experimenting with some other maps for different 2:1 pipes and am running the fuel map for the V&H Propipe right now with excellent results. The surging seems to have stopped but the low idle returns every now and then when coming to a stop after the bike is warmed up. What controls the High idle speed when cold and has anyone else had this particular problem?

RE: surging idle
Novacuum leaks but reprogrammed the fuel map and surging has seemed to stop. What about the low idle and what sensor controls the fast idle warm up? I believe it's the oil temp but just wanted a confirmation on it.
