Never Thought I Would Love It So Much

Hello Rafa and another welcome from Utah. You have come to a great place. Nice looking bike you have, too!!
 
Welcome from New Zealand Rafa.
For the loose mirror, I took a small O-ring and slid it onto the mounting shaft and then bolted the mirror back on. My mirrors now stay put until I adjust them. With the O-rings in place, I can still adjust on the fly without difficulty.
