What is the correct idle rpm for a 500ss MXZ adrenaline. The reason I ask is that I just got a new 2005 and it was idling at 1000-1200 and it would start with two pulls with the choke on half( when cold starting) and the motor shook like it was loose and it seemed to not want to stay running after it warmed up. I would have to give it a little throttle. So I adjusted the idle screw till the idle rpm is at around 1800-2000 and when I ran the sled it took it a while to return from 3000 to 1800-2000 when stopping.

1600 +/- 200 rpms
sometimes after hard runs the idle will hang burning of excess fuel in the crankcase area . if it continues after readjusting the idle take it in to the dealer.
