I have a "late" 2007 K1200GT. Here were my issues, which I think are the most common ones:
1. Twitchy throttle.
The throttle was so overly sensitive that it was difficult to control the bike, especially at low speeds when riding on anything bumpy. Engine braking was overly strong, which adds to the problem. I thought it was me, and tried to learn to control the "sporty" throttle; I gave up after six months of daily riding. Fixed with software upgrade (no airbox change) to version 10.0, which I still have. (FYI, the current software version is 11.1, according to my dealer on 1 May 2008.) The software upgrade made the throttle much less sensitive, and it decreased engine braking to a reasonable level.
2. High Idle / Bucking Bronco Syndrome (HI/BBS).
Rare, but scary. The engine continues to rev (around 3,000 RPM) after closing the throttle. Happened to me several times; one time I could have rear-ended a police car if I wasn't paying attention. Brakes win over engine, but it isn't very nice. Motorcycle is not smooth, also around 3,000 - 4,000 RPMs, especially in traffic in lower gears. I took this as normal until the airbox was replaced. Fix: Replace the airbox last week under warranty as specified in the service bulletin. Bike has been amazingly smooth at all but the lowest RPMs (2,000 or less in 1st gear). This is how the bike should have been all along. I have only had it back for two days, but the improvement was immediate and obvious.
3. False Brake Pad Wear Indicator.
The brake pad wear indicator illuminates on the panel. A visual inspection of the brake pads shows that they aren't worn. Fix: The dealer replaced the front brake pads (both sets). I argued that it did no good to replace only the "indicator" set if the other set would wear out much sooner. I assume that they re-routed the wiring if that was necessary, but they didn't say anything about it. Apparently it can happen to either the front or rear brake.
That's all. I am very happy with the dealer service people. They are great communicators, they are courteous, and they have an unusual amount of common sense for people in their line of work.
Additional Common Problem that I Didn't Experience:
4. 2006 - 2007 Seat Design
Early 2007 model seats are reported to be very uncomfortable. They slope forward and push the rider into the tank. Many owners buy a custom seat to deal with the problem. Outside the US, some dealers have replaced them under warranty. I haven't seen anyone in the US claim the same service. I note that many people replace their late 2007/2008 seats anyway. I like the late 2007 factory seat, it is comfortable for me.
