OK, I'm going to bump this thread to see if there is any new information. I purchased a used, one owner, 2015 1200 GS LC with only 3,000 miles on it. All work on the bike was done by a single dealership, in another state which I won''t name at this time. Today while installing some Clearwater lights, I discovered someone had either over tightened or cross threaded the lowest side fairing screw into the brass nut on the tank. The screw just spins the nut in the tank molding and won't come out. The bike is a few months out of warranty, so I doubt I will get any help from BMW, even though I'm 100% sure the dealership screwed it up. ( No pun intended.) Plus, they're located 750 miles away. I suspect they will claim the previous owner did it, even though he doesn't wrench on the bike. Any new suggestions? I'm not anxious to buy a new tank.
