As I as going to take my R1200GS 2005 off it's center stand today It made the usual kind of spring noise. But when I looked down there was a screw an sort of thick mesh washer and a smaller spacer that could have fit in the middle of the washer.
I'm not sure if they were there on the ground before or if they popped off when I was taking the bike off it's stand.
I am attaching a slightly blurry pic to this post.
Does anyone recognize these parts?
