Help! mirror vibration on my '02

I just got the bike, and I'm leaving in a week on a month-long road trip. The right mirror is stable, and fine, but the left mirror is effectively unusable due to vibration. At night when I look into the mirror I see a dazzling array of dancing lights that makes me think I'm looking at Las Vegas while on acid!

Anybody have any (inexpensive!) methods for curing this problem?

Mirror isolators are available from various vendors, relatively inexpensive and work reasonably well.

Low vibration mirrors can be had at somewhat higher cost.

Some people make their own low-vibe mirrors by drilling a small hole in the plastic mirror housing and filling the housing with lead bird-shot and then sealing the hole with RTV. (oops, noticed you are in Kalifornia - not sure that lead shot is an option there.....lol)

One mirror noticably worse than the other, I'd be making sure that the trouble mirror is securely fastened....

I like the bird shot idea! Does it not rattle? What is RTV, and is there not a lead alternative? The mirror is securely fastened to the bike, so I don't know why it's worse than the other one, but it's driving me crazy and it is definitely a safety hazard!

RTV is Room Temperature Vulcanizing sealant. Available at auto-parts stores, Walmart, etc...

Lead shot is pretty soft, and really would not create a rattle, the fuller the better.

Some #9 or #8 would work pretty well. There are non-lead and steel shot alternatives, but those tend to be reserved for water-fowl loads with resulting larger shot sizes (#4 and up).

The object is to simply add mass to the mirror to absorb and slow the vibration energy.

If it seems like too much trouble, go with the mirror isolators - they really do make a difference (although some may disagree) and are not expensive at all.

This is a link that I found with a simple Google search. I have never dealt with this company before, but you get the idea.

Please don't think me rude, but you are aware that there is also a jamb nut at the base of the mirrors themselves, where they attach to the stem? Loosen and spin down the plastic sleeve at the base of the mirror to access the nut...

Thanks again for the input. I'll try with the isolators first before diving into drastic measures, though I must say I am generally a fan of taking more persuasive action...

The nut you are referring to is the one I checked when I first noticed a problem. It seemed as tight as it could be expected to get. Now that I think about it, I wonder if the problem is at the sort of universal-type joint where the actual mirror connects to the stem. I noticed the mirror was askew yesterday and I had judged it to have been most likely caused by someone — me, even — having knocked it unintentionally. Now I wonder if that connection is a little worn out itself, and the mirror shifted out of place while riding at high speed. I don't think it looked to be adjustable though.

Spin the plastic sleeve down, this will allow you access to a nut that you would loosen to adjust the mirror angle.

If you're serious about usable rear-view mirrors, TPI sells these 5-1/4"-wide Ken Sean rectangular mirrors for, I think, less than half the price of the OEM round jobbies.



The size and moments-of-inertia of these mirrors alone result in less vibration; less stil if you use mirror dampers (I think they're available from KLR.com).

FULL DISCLOSURE: No financial interest on my part; only--if you really care about seeing behind you, here's a path to achieving that objective.

I'm using the same thing, for years!! You can see better, and I like the way they look, too!!!
