Hello to all.... I noticed my rear rim was etched on the right side. I removed the wheel and the housing for the drive line was also scratched also. It was probably a piece of road debris, I hope. But I am checking it out completely (we are heading into the remote areas of eastern Peru). When I rotate, by hand, the wheel from forward to reverse, it seems 100% correct, which I believe says the drive line is alright. The question I have is when I am on the left hand side of the bike and grab the wheel at 3 and 9 oclock I can move it 1 to 2 mms from side to side. Not a lot, but I want to be careful! Is this normal? If anybody could check their bike and respond, I would be very appreciative! There are no BMW dealers in Peru!
