Help with Battery Covers; 1985 K100RS

[duddini]

Hi all,

  I'm hoping someone can help, I've searched here and looked at Max BMW, but can't find enough detail. My battery covers attach with two "buttons" that push into rubber grommets, but there is also a molded-in bracket with a hole that closely lines up with a peg welded to the frame. I know I'm missing the part that mounts to the battery cover bracket so it can grab the little frame bar, but I can't find what it is. The Max BMW web site shows a slightly different battery cover, so it doesn't help. I've attached a couple of pictures.
 Now that I've got the bike running, man am I in love with this ride ! I just need to figure out how to securely mount the covers, and find a coil cover, and I'll be set.

Thanks for any help,
Bob

You're missing a small rubber grommet which should be mounted in the hole in the plastic bracket.
Bmw part #: 46 63 1 236 510.

Thanks, but.....
  I tried (and tried, and tried) to get the rod thru the bare hole, thinking that was how it mounted, and it does not want to line up. Feeling from under the cover when it is attached with the two buttons, it feels like the rod is a bit higher than the hole in the bracket. If you say they are supposed to line up, I believe you; clearly operator error on my part. I'll try again. Max BMW does show the grommets you mentioned, but I thought it must be wrong.
  I appreciate the help, the bike will look lots better with the covers mounted, but just using the two buttons is not secure enough.....I spent about an hour searching the side of the road for one of the covers before I figured that out :)

Normally you should first slide the metal rod through the rubber grommet in the plastic bracket
and then push the two buttons home.

On the other side....on a closer look your plastic bracket have been modified and that the reason that
the fixing points don't line up.
It's rather common that this bracket on the very early models (-83 -85) is broken.

Here is an image of a cover asserted to be for a 1985 K100RS from a thread on this site, for comparison. Yours looks altered/broken. This one lacks the mounting grommet.
