2012 Stock Bar End Mirrors Constantly Loosening

Have the stock bar end mirrors (which I like) but they cannot seem to be thoroughly tightened. Even when tightening as tight as possible they can still be rotated. pretty easily. Is there a technique for torquing them down properly? Thanks

The trick I used when I had them (not very long ) was to remove them and separate the expanding collar portion from the mirror, measure the depth of the part of the mirror that goes into the bar, insert the collar just far enough in so that the bolt will still start and thread properly once the mirror is inserted, insert the mirror and carefully get the bolt started, then tighten as usual.

This made sure the collar was as far in as it could be BEFORE it was expanded by tightening the bolt.

Worked for me YRMV....

You might try blue loc-tite (the low strength one).

It appears as though the collar is in a fixed position so cannot be fitted deeper inside. It does appear however that the small sleeve that fits inside the mirror (the one the bolt goes through) is a too long so the bolt locks in a loose position. I am thinking of maybe shortening the length of the sleeve.

Finally figured out what the problem was. When the dealer put the bike together they inserted the sleeves for the bolt inside the mirrors (as opposed to inserting them through the outside end of the mirror.

Mine held tight for two years, then one began to act up. I didn't take a close look at a fix because I had already decided to replace them.

Glad you found the answer for yours.
