My mirror keeps moving back when going 70+

I tried a variety of hex wrenches but nothing fit, and it's hard to see what that is under there... hard to see/reach.

I presume I just need to tighten it a half turn. Starting to get annoying having to push the mirror back in place every 10 minutes on the freeway.

I'm guessing you removed that black round cap on there,right?Get the right allen.Snug her up.There's a nut underneath that mirror stalk.Might have a look and make sure it's there?Probably a 5 or 6 mm hex wrench.

Check to see if you have the plastic washers too. I take my mirrors off for track days and have to pay attention as there is a couple like uhmw plastic washers that insert top and bottom with the mirror. The Allen has Loctite on it too but I think as long as you have the washers sandwiched in there with the mirror it will hold its position.

There's a little black cover over the hex head

Remove little cover, 6mm hex

The mirrors are telling you to take them off permanently because they weigh about two lbs and they disrupt the flow of the design. Amazin how much better a mirrorless bike looks.

Like piken said, there's a little black rubber cover on the TOP Side of the mirror thats a 6mm hex. Mine had loosened as well and I thought the hex screw was underneath but it's actually on the top.

Yeah, found that sticky top cover and it was fixed in 30 seconds. Found out it takes very little rotation to go from locked in position to sloppy.
