Could be the airbox idle issue. Do a search here first. There is an idle related valve in the early airbox design. It was addressed with a new airbox and related hardware.
Try to check if yours was fixed under warranty (dealer should be able to do a search to see if your bike was fixed by VIN).
Also, have them check the software version, as it was implicated too.
This is a VERY well known issue with the early KGT.
If your bike has NOT had a new airbox installed and it is determined you need it, the parts costs about $400-600 and getting a new one on requires quite a fun day or two of wrenching....I did this myself as warranty had expired on mine. It was not fun. It did not completely fix the problem. It still happens when the bike gets real hot after a LONG ride in hot weather. Bike becomes almost unrideable.
Here's a look at the parts I'm talking about....
2008 K1200GT, Custom Paint, Vivid Black, Aeroflow WS & Aeroguards, Givi E52 Maxia Topcase w/AdMore Lighting, Zumo 660, Suburban Footpeg Lowering, Sargent Seat
2009 R1200GS Adventure, Magnesium Grey/Black, Adventure Cases, Zumo 660, Touratech Unobtanium Accessories
1974 Norton Commando 850 Soon to be a restoration project
