My 08 LT is ready for the 12K service and was wondering how important is checking the valve clearances at this point? I can do all the other 12k required service myself...It also needs F&R tires, but I can get that done anywhere. The dealer quoted me $1300.00 out the door with new tires!! That seems absolutely nuts to me!! But maybe its worth it, I don't know. This is my first BMW motorcycle and absolutely love it!! I want to treat her right, but within reason!
