1985 K100 mirror issue
« on: May 14, 2018, 12:46:20 PM »
Hi. I'm getting closer to getting my K100 on the road. I have an issue with the mirrors. Apparently the last owner had the bike parked somewhere and the wind blew it over. the right side mirror glass got cracked, but is still serviceable, however the left mirror didn't fare so well. The glass is fine, but there's no keeping it in position. it flops all over the place!!  The last owner cobbed it tighter with a bit of teflon pipe tape to tighten it up (unsuccessfully)  So... is there any way to tighten up the mirror adjustment, and is there a method for glass replacement, or am I looking at having to buy new/used mirrors?

I typed mirrors in the search box and got many hits.

3rd thread down will answer your question.

Start using the search box.  Do you understand?

Hi  I do understand. Thank you. (I did try using the search box, but didn't see what I was after there.) Sorry, I will try harder in the future.

Hi. I Did try the third thread as you suggested, but that seems to talk about K11 RS mirrors, and doesn't seem to answer my question. Excuse my ignorance, but is this the one you were referring to?

With the glass removed there is a nut that can be tightened. Alternatively smear black silicone on the ball joint and rotate the mirror head while pushing more silicone into the ball joint. Then set up the mirrors in the required position and wipe of the excess silicone. I did this on my first mirrors which were non OEM and it worked for about three years until I found an OEM set. You can also use super glue but that comes with inherent problems, so you are better sticking to silicone.  :dunno

Hi. Thx Martin. Is there a way of removing the glass in this type mirror without breaking it? Maybe until the budget allows, I could use aftermarket.

Using j o's recommended mirror and then jo's or Imiklosy's method of mounting them is the way to go. Ken Sean mirrors are sold at many online sites.

Which way the wind is blowing at the time of glass removal, seems to be one of the key ingredients on removal success. That and the alignment of the stars. The age of the adhesive also comes into it as well as exposure to the elements. Go slow and easy, or revert to new mirrors or silicone.

I think Ken Sean is calling my name. It sounds like a better option and given the condition of both mirrors, I think itís time to get new! Thanks to all for the info.
