Have this interesting problem with my XB9SX. When the bike gets hot to where the fan must run on shutoff and I go to restart it I noticed that it will idle low and then die. It also will tend to be hard to start. This goes on until the bike appears to go from open loop to closed loop. It runs fine during this when you're using the throttle. Just idle is off. Anyone have this happen before and what did it take to fix?

Intake Air Temperature sensor (IAT) heats-up as engine cools-down.
Hot re-starts can have faulty fuel/air mixture; result of over-heated IAT's signal.
Ride a bit and IAT cools.
