There is no Clymer or other third-party manual for any of the current K1200 models with the "Slant 4" engines. Every once in a while, I leave a request on Clymer's website, but I don't think BMW's production numbers are high enough to cover Clymer's costs to produce such a book, especially with the K1600 models replacing the GT.
Your best choice is to buy the BMW RepRom. a repair manual on DVD, from your BMW dealer. The RepRom is a little pricey, costing just over $100 here in the USA, but it is well worth the money. As always, I strongly urge everyone to buy a genuine copy from their local BMW dealer. Cheap illegal copies are available on the Internet, but I strongly discourage anyone from supporting those slimeball leeches who profit from others' hard work.
The RepRom has its own software, and requires Microsoft Windows to run. I run it under Windows 7 on my Mac using VMware with no issues. In the past, I ran it under Windows XP.
The RepRom includes detailed procedures for checking the valves, flushing the brake fluid, and much more. The valve check is non-trivial, requiring you to remove the radiator. After you reattach the radiator, you need a special vacuum filler tool to replace the coolant.
Another source of maintenance procedures and info are various how-tos on k-bikes.com, i-bmw.com, and some superb work by SemperFi on the BMWMOA website.
