Vibrating mirrors
« on: July 11, 2011, 07:45:13 AM »
 Does anyone have any suggestions on quelling vibration in the mirrors?

 I have a set of aftermarket replacement mirrors, stock style, on my CB500. They get pretty blurry at times. I was thinking about putting a rubber washer between the lock nut and the mirror mount on the controls.
 Besides "get a set of genuine Honda mirrors", any other ideas?

 Funny thing is, I have this exact same set on my XS650 and they don't blur or vibrate nearly as much. You'd think they would be worse on a big twin.

Yea I csn't figure it out either.  Got Honda stock mirrors & left is steady, right is crap.  I think rubber might make it worse but it would be easy to try, let me know if I'm wrong.

I don't think that perfectly clear is possible. If you can feel the buzz in your feet and hands then you will see them in the mirrors.

That said, the key to reducing vibrations in the bars and mirrors is mass. That's why modern bikes have the weights at the end. Replacement mirrors often are lightweight plastic, and while it would seem that the plastic would absorb the buzz better than metal, reality is that a heavier weight mirror stem would quell the buzz better. There is a company that sells a long weight intended to be inserted into a hollow bar like ours (I think it's called the Bar Snake). It might be an option to consider if you don't want to try bar end weights.

I've got stock original mirrors on my CB500.  The glass on the left mirror fell out on me when I was riding around in the yard just after I first got the bike up and running.  It's a big yard, 1 1/2 acre, took me awhile to find the glass but find it I did and it was intact.  The rubber in between the mirror glass and the metal is what apparently holds them in, this rubber had cracked and shrunk enough that it would not hold the glass snug anymore, so I put some silicone high temp gasket sealer on it to "glue" the glass to the rubber.   This mirror vibrates enough that at freeway speeds everything is a blur, but the right hand mirror stays perfectly clear.

I run these on my Triumph and couldn't be happier. They're a little expensive, but worth every penny. I get no vibration what so ever at any speed.

Experiment. Nylon might be better than rubber to insulate. I haven't seen barsnakes in a while, but that's the idea. Of course barsnake won't work on Cbs with the wires in the bars. So end of the bar barweights might help.

Don't recall its an issue on the 750s. So the smaller 4s buz a little more.
