I have a 2006 St3s with about 7k. I'm experiencing a problem with what I would call "fast idle". When I start up from a cold situation the bike runs fine but the idle won't drop below 2500-2000 for about 20 to 30 mins. The shop says that maybe the Leo Vince SKB exhaust may(?) be the prob, or mapping, or??. After a time span every thing runs great but it's irritating to sit at a light reving at 2500. All else is great and the rides in Oregon and Washington are beyond belief. Any help with my small problem will be greatly appreciated.
