I noticed today that, while riding, my left bar end came loose. Not completely loose just partially, and strangely enough the vibrations were reduced. I tested it by loosening it completely and it got worse, I tightened it completely and it got worse. There seem to be a happy medium on tightness which minimizes vibration. You gus should try it.

I just changed mine to a much lighter (and nicer looking XD) aluminium alternative, and i dont feel any change so far.
Holding on to the stock ones for a bit just in case though...

Never tryed loosening them, but heavier should be better, some of the light, pretty looking ones don't do anything.

thiink about it. it's a vibration damper. if you loosen is just the right amount, instead of dampening, it will set up a harmonic which will completely cancel the vibration the bars introduce to it. if you want the vibrations completely gone, take one off and pour lead shot into your bars. don't pack it tight, just fill it 80-90% and the lead will not only slow the vibrations down, but cancel them for the most part.

makes the bike feel so much better too.

More than anything else, carb balance and engine balance (one cyl same as the other for compression valve clearances etc) is more vital than anything else for keeping down the buzziness. But bar position, weight and angle all do ahve a part too. The 30 degree angle of the 89 clip on's as well as the fit of the 89's make it just about the best setup for the GS.
Cool.
Buddha.

Ohgood is right on target . . . lead shot ("bird shot" is probably best), stuffed gently inside your bars. I didn't want barbell weights hanging off my handlebars, so I tried this old trick and it worked GREAT! Very noticeable vibration damping.

In fact at one point I had drilled a separate hole for the lever housing on one side to fit my heated grips. Forgetting the hole was exposed under the throttle housing, unbeknownst to me the shot was slowly bouncing out of the handlebar, into the housing, and out the drain hole. It wasn't until I heard a couple of "pings" when washing the bike and when my starter button started sticking that I realized what was going on.

What I also noticed over time was the buzziness was slowly coming back. I didn't put two and two together until I had to fix the starter button. Turns out as the lead shot started to deplete, it really affected the buzziness. Once I plugged the hole and topped up the shot, . . . buzziness was gone. It really does work great. You just have to remember that it's there if you ever take the bar ends off or  . . . . You can put some kind of a plug in the end if you don't want it spilling out in that case.

sounds like you had a 'kyle' moment, aka homer simpson - DOH !

ah motorcycles they vibrate and things come loose.  when your filling are coming loose then you have something to worry about 

Absolutely . . . .  DHOH! 

The starter button would stick, then mysteriously unstick, then stick again. It was driving my NUTS!  The shot was jumping out of the old housing hole, then bounce around inside the housing, get stuck in the starter switch, then bounce out again. All it took was a piece of electrical tape to fix the problem once I knew what the heck it was.
