I think my Interstate idles a bit fast. I especially notice it if it is running hot. I understand it cannot be adjusted (out of warranty then?), it is self-adjusting. It's just enough that when I'm at a standstill, I keep waiting for it to lower. I may be used to my Shadow, whole different system, and choke, I get that. With the high temps here most of the year, and running the bike at 70 + much of the time, wouldn't it be better over the long run if it idled slower?
