Thanks, I didn't even think to take it off to adjust it... Where did you get the extenders?As far as tightning, one word - Loctite -
For adjustment, when you remove the mirror, there is an adjustment nut inside at the bottom of the mirror. You need to loosened this nut adjust your mirror and re-tightened the nut. This is a trial and error to get the right position by the way.
You might also need to go to mirror extender as many of us have done.
Hope this helps!
Even if money was irrelevant to you, this kind of shenanigans would never fly in the automotive industry, and shouldn't fly in the motorcycle industry.It's only money!
I did this before taking the mirror off - worked just fine until I went over 45 mph...The trick I found with the mirrors is only turn them clockwise, if when you have it tightened down and the mirror is too close to you, continue to turn clockwise to the correct position. If you go counterclockwise the mirror just loosens. The mirrror shaft still turns when the top nut hits the bottom. The nut/screw on the bottom needs to be tightened a little also.
