Putting extra weight into the handlebars? didn't make any di

[kz]

Hi,

The bike has vibrations at approx. 115 km/h, there are a lot of thing to try first, see other threads there the topic has been discussed.

My GS1150 1984 has handlebars with hole, like a tube.

I have heard that if you put in extra weight into the handlebars it could decrease the vibrations.

Anybody who knows if this is worth trying?

I use sand, I've also heard of using lead shot, there is also a kind of counter weight that is inserted into bar ends and tightened, not sure who makes or sells these, they're used in sportbike clip-ons also. The sand does help to give the bars some mass, thereby lowering the frequency at which the bars vibrate, and lengthening the time it takes for my hands to fall asleep, I put a throttle lock on so I can shake my right hand also,to wake it up!

Thanks for your reply,

I think I will give this a try.

Karl the GSX1100EF(GS1150ES for the US) came stock with bar end anti-vibration weights, if they are not on your bike there is your problem.

Dink,

I have the anti-vibration weights mounted, as I wrote in the post http://www.thegsresources.com/_forum/viewtopic.php?t=6839&start=45 your earlier suggestions has decreased the vibartions already, but I want to get it even better.

Sorry,

What do you mean with bb's?

Just got stainless steel blastering "sand" delivered.

It feels a little bit heavy, is where any risc involved if you put to much weight into the handlebars??

like in a BB gun. small round lead or copper balls as in a hunters shotgun shell. Very small ball bearings etc.

Karl, the two things I have gathered from the discussion threads that reduce vibration is to re-torque the engine mounts and to synchronize the carbs precisely. I can vouch (relative to my 750E) that synchronizing the carbs made it into another bike from a vibration standpoint. When I first had my 750 running, it vibrated so badly I could feel my hands after fifteen minutes of riding. Now with the carbs sychronized as they should be, the bike does not vibrate at all. All day ride and my hands are fine. My 85 1150E almost does NOT vibrate.

I think it's true that if all is in correct balance and the correct parts are present and correctly installed there should be not too much vibration. However if there is...and often there is...you have to interfere with the harmonic of the vibration. Adding weight to the bar ends, if that is where the vibration is, can be accomplished with bbs, lead fishing weights, sand or anything else your imagination can come up with. A nice cheap solution s a lead plug from any concrete outfit. These are designed to be inserted into a hole of a given (much variation) diameter, and then a screw/bolt is driven into a hole in the center of it, thus spreading it out. Usually something is fastened to the concrete wall with the bolt/screw...just like drywall hangers, only heavy duty.
Putting two of these plugs into the bar-ends of my '70 Triumph 500 eliminated vibration in the bars. Later I found that this vibration was caused by the vertical twin cylinders causing a vibration in the frame and could be eliminated by putting a brace into the frame. In any case...

try it...it's easily installed and easily removed.

Karl after a brief discussion with an old timer mechanic, I suspect most or all the vibes present in GS/GSX Suzuki's can be traced to the clutch baskets, the movement, wear or even slop being the cause of most of the out of balance forces.

You could always go with an aftermarket set of bars. I have Daytona's on my 750ED and have been happy with them. They are solid alloy and therefore do not use bar end weights but do mount directly to the top triple clamp giving a sport riding position. I will add that most old GS bikes I have ridden all had a certain amount of buzz to them. I think that is just the nature of the beast and unless you are willing to do a complete balance job no simple fix is available. Ride On, Ed.

Would having the hub rebuilt by someone like falicon help vibration?? I do know they rebalance the hubs after reassembling them. Earl give me a shout if you want to go that route...know where a couple are. :lol:

I have changed the clutch basket, due too that the inner ring of the clutch basket came loose.

No difference in vibrations after the change....

I still have the carb balance at running engine and stainless steel blastering sand into the handle bars left too test....

However, the vibrations have decreased a lot already, since a started all this.......

Was your engine ever used to drag race a lot??

As far as I know, no, but you never know....

The first owner changed the camshafts as the bike was brand new, so he might have been heavy on the throttle.?

I was just wondering if it were possible that your crankshaft is a bit twisted
i removed vibration from my bike by a combination of the things mentioned. The thing that finally cured the problem was an electronic ballancing of the front wheel.
