Maybe you could get a small weight slightly smaller then the diameter of the bar, coat it in RTV or someother silicone sealant and push it up into the bar, far enough that it won't interfere with your bar end mirrors? Just an idea.. by the way, what mirrors did you go with?

 

Man, that was fast, lol

They're actually mountain bike mirrors that I found at a local bike shop, they seem to be of very high quality too, so I don't think I'll have to worry about them falling apart. I have them mounted so the mirror is under the grip, and the lense is on the inside, not sticking way out like the pic shows. Looks really good, IMO, and although you wouldn't think so, I actually have a good field of vision with them, even though I'm looking under my arms, lol. Any time I change lanes, I always look over my shoulder, so the mirrors are only there to stay legal, really

I thought about it a little bit, and I think I might just buy a big tube of silicone, and use a cauking gun to pump as much into the bars as will fit. I think once it cures, it will work out pretty well. Can't make it worse (I hope :rofl: )

 

Confused yet? :bleh:

OK, I took off my hideous stock mirrors and found some cool bar end ones to use, the problem is, I no longer have the bar ends on the bike (obviously, lol). Not surprisingly, I'm getting some serious vibes in the bars that will drive me nuts if I don't fix it. It's not bad at all when just cruising around, but when you really whack the throttle, the bars start to buzz like crazy.
My logic is, if I fill the bars up with something, it will kill those vibes I'm now getting. Does anyone make some form of liquid that hardens into a rubber like material? I'm thinking that once it solidifies, the rubber will drastically reduce most of the vibes and I'll be a happy dude.
Let me know what you guys think, and any other suggestions would be appreciated.

Oh yeah, I called up Streetfightersbydesign today, and ordered a Barracuda flyscreen like U235Power has :supsmiley . Can't wait till it shows up, I'll post pics when it's mounted up :headbang:

There is, or at least was, a product called the Barsnake which came two ways. One was a fairly solid piece of heavy rubber type material that you pulled through the bars, the other, for more complex shapes was a two part liquid that you mixed, poured in the bars and let set up to a pretty hard consistency. I used it on a Sportster and it did definitely help the vibes. It was not especially cheap if I recall, around $40 at the time
Of course you could just put aftermarket bar ends on it I'm sure you know. I'm surprised its all that bad, I took off my stock ones, put on much lighter lockhart phillips models and didn't notice much, if any increase.

 

several companies make hardware to retrofit tubular handelbars with stock weights. some came in my Convertibars riser conversion kit. i can't imagine they are too expensive.

I have done this in the past two different ways. Both times were with a single tubular K&N Superbike bar. Both methods were cheap and effective.

Method 1
Pull the plastic caps off both ends. Fill the last 1/2 of one of the bar with RTV (Silicone Seal). Place the plastic end-cap back on this end. Duct tape the handlebar to the wall with this gooped end downward. Let the RTV set overnight. Tip the handle bar open end up and fill the handlebar with clean "Play Sand" from the Hardware store. Goop up the last 1/2 inch with RTV and replace the plastic end cap. Again stand the bar on end with the newly gooped end up this time. Next morning install handlebar on bike.

Method 2.
Buy RTV in the 300 mL caulking gun cartridge. Remove both plastic end-caps on handlebar. Ram the caulk gun in one end and pump und goop comes out the other side. Replace the plastic end caps. Wait one day for the goop at the ends to cure. Install bars on bikes.

These methods could easily be modified for use with a single ended clip-on type bar. And they could be easily modified for use with large bar-end weights instead of plastic caps.

A note on bar-ends. There are a number of companies that sell anodized aluminum bar ends. They look pretty trick, but they totally defeat the purpose of a bar-end weight. The whole idea is to have a big-dumb steel weight. The big dumb weight is what lowers the natural frequency, and thereby all the harmonics and resonances, of the handlebar vibration so low that it is less percievable. Also it takes a lot more energy to buzz a heavy mass on the end of a stick than it does to buzz the stick alone.

The stock big-dumb-steel-weights are a good thing.

BTW, What bars do you have? Are the stock ones hollow? I haven't pulled mine so I don't know. If they are solid...

 

you could

try here

go to the Bandit 600/1200 page and scroll down to Touring Products and you'll see some bar snake products.

there's also superbike gel grips ... I've heard those help, too (and they're on my lower-priority mod list as well)

 

Thanks alot for the info, guys. I still have the stock bars. Can't look into any type of aftermarket bar-ends, because the mirrors are now plugging the hole that the ends would go into

Willie, did simply filling the bar with silicone make a noticable difference? It seems to be the easiest route. I could just do that, and when the material sets, gouge out the last 2" or so that would be in the way of the mirror when it's stuck in the bar.

Thanks again, all :rockon:

 

Buck shot is the best bang for the buck. istols: It is very heavy so it totaly quells the vibs.

This is what I have used in the past!

 

Welby rotate your bars up and fill with RTV.Thats what I did and had a friend machine me some stainless steel bar ends a little longer than stock.With gel grips it works fine.Don't notice vibes anymore.Don't use alum.bar ends as they are too lite.Ride safe........................Les

 

Go here. Solid and liquid stuff that goes inside the handlebar to eliminate the vibes.

$27 for solid. $48 for the liquid.

Greg7 beat you to it, but thanks Tim

Little pricey though, I'm notoriously cheap (Due to lack of funds, not any desire to be a cheapskate). I'm going to try the "fill it up with silicone" route and see how it goes. :wacko:

I don't know how this might work but if I were doing that I would consider filling a small portion near the grips with some #9 shot or the like, then 'trap' it with the silicone. That would seem like it would give it some heft to simulate the lost weight of the bar end and the silicone should trap the shot sufficently to keep it from rattling. Just a theory, never tried it for myself.

Sounds like one of the best, and most cost effective solutions so far.

Let us know what happens as my GSXR750 Streetfighter has a tubular bar and I want to kill the vibes it has too.

Seems like something more liquid than silicone would be better for pouring into the bar.

I've been trying to think of other media's to use for this. If you could plug the ends, some kind of lightweight oil would be perfect.
