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?
