Yeah, so since the OEM mirror stalks on my bike are apparently made of aluminum foil, the process of trying to unscrew the left mirror (so I could install extenders) has stripped the mirror stalk, the hole it screws into, or both. (I think the hole can probably be salvaged if I can get a hex key that can apply enough torque to the top of the extender screw, because I've been able to get the extender screw most of the way in. And if not, the bar sheath that contains the hole is a replaceable part.)
I've taken the mirror off once before (to install a wind deflector on the stalk) and had trouble that time too, but this time it was so hard to move that I basically had to tear up the threads just to get it off.
Is this just me, or are these parts made of really soft metal?
Is there anything I can do to salvage the threads on the mirror stalk, or do I need to buy a new mirror?
