I have just returned from an interstate ride and decided to try and lessen the handlebar buzz.

I have tried end weights in the past and with little success, so i tried my own solution.

I am running RT bars on an RS. 

I called in at my local fishing tackle shop and purchased some lead fishing weights (snapper leads) that looked about the same diameter as my bars. Ripped the grips off and inserted lead weights. The fishing weights were long torpedo shapes and slightly bigger than the bars. No trouble, a little light work with a hammer saw them go in (more hammer work) tightly. I used one whole packet (3 weights) on each side. I just knocked them home right to the bend. I would guess half a kilo each side.

I think is has drastically reduced vibration! Also adds a new steering dimension to the old girl. She falls into the corners more easily, I like the feel. I ride pretty hard as my riding buddies have Ducati's and even though I am the old man of the group, I make sure we keep with the pack.

I have read that some people have used lead shot to fill the bars but this way was really quick and easy, half an hour of fun and it was done!

But where do you hide the pot now???.
Mind you I'd keep quiet around your fisho mates, you know.

I owned a 1989 Kawasaki Concours with clip-ons and they came stock with tiny (2mm?) lead balls inside the handlebars AND handlebar end weights.  Changed out the grips and found the little buggers inside by surprise - man they are hard to recover from the grey concrete floor, magnet didn't work worth a dagnabbit...maybe I had the polarity wrong? lol!

I have Manic Salamander 18 oz bar ends on my K100.  They weight almost three times as much as the OEM ones.

The other thing I do is keep the throttle bodies synched frequently.

Use an East West magnet the North South ones are useless picking up lead.

I used to get annoying tingles from the handlbars and then somebody on this forum had found a way to overcome play at the clamps by placing a  washer with a slightly  smaller diameter  than  the rubber bush, between the standard washer and the bush and then tighten .
This would exert pressure on the rubber bushes   without metal to metal contact on the clamps .

As my bars were a bit on the soft side, I tried it and the bike felt different with virtually no tingles and firmer steering.

Just a thought

Also as duck says keep your throttle bodies in sync.

I have also noticed that if you get a buzz through the bars at your cruising speed, try closing throttle very very slightly.
 I did this on my first k100lt and she would go turbine smooth. My current k100lt does this too.
The previous owner of my first k was really pissed off when I told him. It was the only reason he sold it.

I get no vibration from the bars or the foot pegs.  Such a comfy bike for long distances..

I'm a fairly new-by to the Bricks, really love my R12C and still use it for multi-day 500km/day+ riding this summer.  But I really want to change over to the higher performance K that I bought, it's a freakin' Rocket Bike ya' know....but the handlebar vibration is really annoying - my right hand thumb and first two fingers sound asleep after about 30 minutes and then pain all night.

So a long and hearty search of this issue (well-documented EVERYWHERE) brought me to this seemingly simple solution.  Got it together this morning to remove my bar clamps and insert a smaller (about 1") washer underneath the stock fender washer on top and reinstalled.  Went for a 90 minute ride (occasionally into the Stratosphere ;-) ) and neither hand had ANY tingles!  Beauty and so easy and cheap too - thank you SIR!  Reducing the handlebar vibration 212902   Reducing the handlebar vibration 212902   Reducing the handlebar vibration 212902

I went looking for these (Manic Salamander) bar ends but was unsuccessful in my hunt.  But I did come across some Brushed Stainless bar ends made by HVMP (about 15 ozs.).  For my K100RS I had to buy lighter ones (? - they make and sell 18oz. bar ends) but even so, after installing these the handlebar buzz was reduced substantially, and they look nice and extend the width of the bars by a noticeable amount.  I bought directly from HVMP.com - about $90 CAD with shipping.  Product Code: F4UX110

cheers
