I have replaced the stock mirrors on my Ultra with some after market mirrors from HD. I have noticed a lot of vibrations with the new mirrors that I did not have with the old mirrors. I dont think any of the brackets are broke under the fairing as I changed them out just a couple months ago. Do you think that the vibrations are because the new mirrors are not made with the same type of mirror glass that the stock ones had and it is picking up and showing the vibrations more because of it? They really vibrate when I am stopped.
