Last July, I purchased my dream motorcycle, 2013 R1200GS with 11,000 miles on it. The original owner was an engineer and had a detailed Excel file for all the maintenance completed on the bike. I have owned a Kawasaki 350, Suzuki GS850G, and a Honda 1200 American Classic before this BMW. I enjoy doing my own maintenance, but I am finding it difficult to locate a solid "do-it-yourself" manual for the BMW. I use YouTube as best as I can, but often I find having a manual with torque specs, etc., as a big plus. Do any of you have any recommendations? Also, would you recommend purchasing a HEX 911 diagnostic unit and is it worth it for the self taught do-it-yourself person? Thanks in advance!
