I have a 2012 GS650 which I've had in the shop four times because it has trouble started when warmed up. Each time I was told the ACR needed adjusted, but when I took it in for the 12k mile service I mentioned the problem, again, but this time, after the tech looked at the bike, I was told that there was a recall for this problem. The service writer that I saw when I picked up the bike said he didn't even know that this recall existed, so if any of you have this same problem make sure to mention the recall to the service writer just in case he/she doesn't know about it.
