I was washing my "new" 2007 Burgman for the first time today and noticed the anti-vibration weight on the LH end of the handlebar seemed a little loose. I jiggled it around some and it came off. Hmm... I thought these were supposed to be bolted on. It went back on with minimal effort and seems fairly secure with the big rubber "bulb" filling up the empty socket, so I don't think it will come off without some contact. (I don't think it will just vibrate off)

Question - is that right? Or is the 1/4 inch of threads sticking out on the inside tip supposed to screw into something in the bar end?

Thanks.

First of all............!!! NO question is dumb..if you don't know the answer.

you need an impact driver to seat the bolt and what is does is just cause the rubber "bulb" to expand inside the hollow handlebar!!! I have had both of mine off and I do believe that the rubber insert has a metal thread imbedded in it. When you really snug up on that bolt - it pulls the rubber insert snug against the backside of the bar-end weight...!!!!!!

The 1/4 inch of thread does not screw into anything other than the nut that compresses the rubber bulb. As v8eyedoc noted, all that holds the weight in is friction between that rubber and the inside of the handle bar. Having them work loose is a common occurrence. It's a good idea to keep an eye on them so that you don't loose one. If they work out reinsert them and tighten the screw up again.

Thank you both. I did tighten the Phillips head screw after I re-inserted it, so maybe that expanded the rubber bulb and made it a little more secure.

I will keep an eye on them.

I totaly disambled mine and ground the square part that fits in the rubber down about 1/8 inch, then put a brass nut that I ground the corners off enough to fit inside the bar. This supports the weight better and alows you to tighten it up some more. See Pic

Thanks, Dave. Next time I have it out, I will consider this. I don't have access to a shop, so my mods are limited. Looks like a good idea, though.

No need for a grinder. A $5 mill-ba$tard hand file will do it in about 2 minuets. Just pull it all apart, file the square part down some and reassimble. I used a brass nut with a small peice of alumimn tube fit inside that the screw goes thru. Much less wobble. Thoses weights are on my sons Ninja 500, that I also poured about 10 Oz's of molten lead in the clip-on bars.

Update

A mechanic friend of mine here at the dealership looked at the assembly (removed from bar) and said "simple fix". He took the nut and rubber "bulb" off and slipped on an 8mm (?) washer before reinstalling the nut & bulb. Took it out to the bike, slipped it into the bar end and tightened the phillips screw. VIOLA! Much better! 5-cent 5-minute fix.

Dave_J, what did that $5 mill hand file do to you to make you call it a bas%ard?:p
I know I need to grow up but why start now.

Partially my fault, I think

I was going to just edit my last post and add this, but I am not able to. So, here goes:

Part of the blame can probably be laid on me. After becoming more aware of this loose piece, I found myself inadvertently grabbing a big part of it each time I put the bike up on the centerstand. I will now be more careful to grab the actual handle and not the extension.

Aha, you Air Force guys. Always doing it backwards.

Model28, you'd be suprized how many people do not know that there is such a name for a file. It is about the middle of the roughness in mill style files. On steel it is the first in my hand followed by a Mill Smooth. ;) http://en.wikipedia.org/wiki/File_(tool)

My 07 doesn't have any, I wonder if somebody took them off?
If it's like mine, you would have a hollow bar that you could stick your finger into on the LH side. Not sure if the throttle side is similar.

It should have the black weight on each end that Dave J posted on the previous page on Post #5. If not, ??????

Bástard is the name of a specific style of "cut" applied to files, those in all being rough, middle, bástard, second cut, smooth, and dead smooth.

Most of what you see now are the bástard, second cut, smooth with the two roughest and the dead smooth not commonly available...

I too have a 2007 and likewise was having the same issues. Finally I pulled the bar end weight off and after cleaning it and the inside of the bar with some rubbing alcohol I smeared some red Loctite on it and reinstalled it. I tightened the screw as hard and I could and left it alone for an hour or so before taking off on my next ride. Been holding fine ever since.
