I'm not familiar with what you have with those mirrors Richard but I have had the same type of problem with other mirrorss on my bikes in the past doing the same thing and lock tight ended up being the solution for me. You might want to start with the blue lock tight and if that doesn't work then use the red. The blue will allow you to remove it if you ever have to and the red will allow you to remove it with only gorilla efforts. Good luck!I’m running with the Kuryakyn Scythe Mirrors on my bike. I cannot keep the left side tight. The shop put some lock tight on it yesterday then about 3-4 miles down the road it was loose again. They told me they could put an epoxy on it and cement it in place. This morning I got to thinking about another idea. These mirror stems have that little set screw. I was thinking about taking it out and drilling into the stem screw then put the set screw back in. That should keep it from ever moving again and allow me to get it off easily if I need to. What do you guys think? Anyone else having trouble with this mirror?
