Bar end Weights

[metalmonkey]

I'm trying to get then back on the bike, and for whatever they just won't tighten up. The screw is tight adn fully in, however they can just pop back out again.

Whats going on, what am I'm dioing wrong. This is really annoying me as I ave no idea, how are these things meant to held in place?

[Drew Carey]

I had that a while back, are you pushing the nut into the bottom and then trying to screw into that???? Or is the nut still in the bottom? I found that if you extract the bar end, bolt and the nut together, put it all back together outside of the bar, then, slide it into the bar and then tighten up. Found that if you don't do it this way the nut on the end doesn't fix to the bolt properly.......if that makes sense?????

[metalmonkey]

Thats what I'm doing, I have put trhe entire thing out, put it back togther then put it back down the clip on (handle)

Anyway I make it tight and it just falls out for FFS! Why is it doing that?

[Drew Carey]

Odd......are you pushing hard on the bar end when tightening? At the bottom of the barrel there is an "insert" where the nut sits in and I found that once seated in there correctly and tightened, the rubber packing is compressed and grips the barrel and it was held in place.

Ah I see, thats where I might be going wrong! I shall go have a look at that and see if I can get it all in place. Plenty shall be applied to the headted grips as well hopefully stop the dam things moving about!

Where is the insert in the bar? I can't see anything is there something that is meant to be down, or is it a groove that it is meant to fit into?

At the moment it is doing nothing and the screw just spins around this is really annyoing I need to beable to use my heated grips and the moment I can't.

The bits of the barend should usually be assembled (from outside to in):
Bolt, barend (largest bit of metal), rubber tube, nut (with grippy surfaced inside to bite into rubber). There will sometimes be a washer or two in there as well. Put the whole thing into the end of the bar. Tighten up the bolt (usually an alun key head). As the bolt rotates through the nut, it will cause the nut to bit down onto the rubber and squash it from long and thin, to short and fat. This makes the barend's diameter effectively increase, causing it to stick inside the tube (which is what you want).

If you are having difficulty putting it in, I'd say one of the following (from most to least likely):
Some existing bar end bits are still in place- usually caused by the existing rubber tube being stuck in. An alun key hooked through the hole, or small spring puller if you have one can usually get it out.
Rubber Tube is catching - The rubber tube has become denatured and is stuck "squashed" and is too fat to fit in.
Wrong sized bar ends for the clipons/bars - EG the diameter of the hole in the end of the bar is different to that of the barend weight.

If it's not catching, it's usually either the bar end isn't assembled correctly, or that the rubber bit is chewed up and won't stick properly.

HTH. Oh and make sure the throttle doesn't stick with the barend in place. If it does, loosen the bar end, move it out a bit and then re-tighten.

I only have one at the moment, however its the orginal bar end.

It fits in fine, its just that it will not become tight, even when it does it can pulled out again! I lost one through this already.

I just don't get why it won't stay in place...

[Ceri JC]

Have you inserted/removed it several times? It's possible that the rubber bit has been chewed up and isn't compressing properly.

Here's how it should work.

[metalmonkey]

Done all of that nothing work its fubar, the screw just spins around, when it does get tight it still lose and come out with a bit of a tug, when I move the throttle the bar end weight moves with it.

Do I need to start again and just buy a new throtle tube, new heated grips and bar ends? I just really fed up, something that should just work won't.

Is there anyone that can pyhsically help me do this? As I'm at loss what I need to do now.

[rigor]

Tighten it up while it's outside of the clip-on. Is the rubber compressing and squishing out properly? Is the bolt and nut in OK condition (not slightly stripped)

[Stu]

can you bring it to soho tomorrow?

[Ceri JC]

What rigor said. Is the bolt head (and hence rubber bit and nut) just rotating in the bar end? Get yourself along to Soho, I'd be very surprised if someone can't fix it there and then with the bike's own toolkit. :)

I had this problem when I fitted a new bar end (a replacement for the one which fell out). I tested it when not fitted to the bar and it turned out the compressing nut was not gripping the rubber bung and thus not working correctly. I had to tighten it up in my hand slightly before inserting it in to the handle bar, someone on here also suggested a little silicone sealant would help hold it place once done up.

Nope I'm working as usual all w/end.

Yeah the screw does moves, nothing happens doesn't get tight then the dam thing just come out again.

[Spokey]

Easy peasy - take them out - remove the steel tube bit from inside the rubber, file a bit off it ( couple of mm should do ) reinsert into rubber - refit, tighten up - Job jobbed ...

HTH

:cool:

Just a quick thing, you've just fitted heated grips? We had this issue, the outer piece of the heated grips meant that the bar end wasn't fully in, so when tightened you could wobble it and the bar end could be pulled out. I found the solution was to shave with a knife the tiny piece of excess rubber. Or, roll the rubber back a little so the bar end is fully in.

[mustnt grumble]

Any resolution to this Bluethunder? I've just fitted heated grips today and have exactly the same problem. No matter what I do the throttle side bar end will not secure itself. I honestly can't see how the rubber bung is supposed to 'expand' as you tighten the screw.

[Dangerous Dave]

Are the grips longer than the handle bar?

+1....you can either use a stanley knife and gently shave off the excess rubber (not the grips, but just the little piece sticking out). Or........do what I did which was to simply role the rubber back gently till the bar end is flush with the bar and then tighten and have the rubber overlapping the bar end.

I was gonna say fit the bullet type bar end weights, they are heavier and are the same diameter as the handle bar so the heated grip fits over them. Just in case there is ever any warranty issue with the heated grips.

I still haven't sorted this yet, some how need to get the weights back on but, still not sure how do it! My grips are working which is great, but needs to get the weights on. However when I get some time I will get it done.

[Tantilus]

I have exactly the same problem and have lost a bar end no longer than 5 mins ago. So I need a new one before even attempting it.
Sorry I can't be of help at present but trust me I know what you're going through! I'm taking mine to someone today to fit, if I get any joy I'll let u know. It's driving me insane!

Came across this problem on my ex's bike a few months back. Basically, the bolt was at the end of its thread before the rubber was compressing - deteriorated rubber due to age. I put a slightly oversize nut between the weight & the rubber & the fastening nut in its normal place. This meant the nut had more thread to run up & compressed the rubber further giving it more grip - problem solved.
