In this video we take a look at the Akrapovic Carbon Fiber Mirror Caps.
I show subtle things to watch out for during the installation such as making sure the mirror adjustments work and do not cause a "mirror potentiometer defective error".
I also demonstrate how to fix whistling from wind using silicone, which seals against water/air, is chemically resistant, and easy to apply. Drive a bit after so that the air pushes the silicone into the correct locations, but don't go too fast or in a dirty area as it needs to cure for a day.
