Has anyone installed the BMW bars on the GTL? It looks pretty easy to me. Someone at the dealership said I should let them do it because the bars attach to the engine block and a mistake in torquing could crack the block. He said, too tight will crack the block and too loose would cause the block to crack if the bike falls over.

First, I have a torque wrench and know how to use it. Second, is the engine block really that delicate? I can see the possibility of stripping out the bolt hole, but cracking the engine block by not getting the torque exactly right? Really?
