Well, there is not much to see really once it's installed. The pic below shows a different bar-end weight from stock provided by Yamaha. There is a hole in the middle to allow the screw to go all the way through, not threaded through though which I think would be better to give it a tighter fit. Admittedly, it's not the prettiest setup. I would like the bar-end weight inside the handguard, but oh well.
http://i440.photobucket.com/albums/q...ah/photo-4.jpg Here ( http://www.vibranator.com/ProductDet...D710%2DN%2D003) is the vibranator. Mine is slightly different as it is for use WITH the handguard. Mine doesn't have the rubber at the end. Instead, a threaded hole is at the end of the shorter cylinder, which allows a long screw go all the way from the bar-end weight, through the handguard anchor, and connect (loctite) to the vibranator. The vibranator has some weight, but not a whole lot. With the setup, the vibranator doesn't touch the inner wall of the handlebar. Hence, it allows the resonance from the vibration to dissipate, so it claims, and it works for me. Some bloggers even say it is better than Flexx handlebar, foam handgrips, and other products that claim the same thing. Best result still comes from the combination of both the bar-end weight and the vibranator IMHO. |
I've been experiencing horrendous vibrations on my Ten for the 4,000 miles I've covered (owned bike from new).
I had the Yamaha engine bars fitted on the first service and noticed after running it in very bad vibes, especially between about 4,300 to 4,800 rpm. The bars eventually cracked around the centre mounting plate (no surprise there) and I returned them to the shop and had a full refund. Since taking them off the bike has stopped vibrating and feels like a different bike; I can only assume the engine bars are/were the cause of the vibration. |
Well I'm now suffering bad vibes after a session checking the valve clearances.Again I'm convinced this is down to a nut not torqued to its sweet spot as josephau puts it.As the tank and engine bars were removed I suspect it is one of their fixings to blame.
I've had this before with handlebar vibes and it was down to a combination of handlebar/bar brace position and tightness of the nuts in the end.Bloody annoying because it is really intrusive at 3500 to 5000 revs. I've just torqued the front engine bar nut to the correct value hoping this is to blame, will test it when the monsoon subsides. Incidentally my engine bars are still crack free after numerous drops offroad and using them as jacking points.The paint finish is abysmal though. |
Well guys, Kev has just designed a set of spacers weights to fit to your original handle bar, send Kev a pm as he is planning to sell them worldwide.

I've removed the engine bars and bash plate but the vibes are still present.
Once the tank is near empty I'll remove and remount it to see if that is the problem. This is seriously giving me the hump after almost 13000 miles and daily use the vibes were never an issue, it now feels like the main bearings are going which they aren't of course. I can't think what other cause there could be, any pointers appreciated chaps? |
Well I've removed the tank and re-seated it but still no remedy to the harsh vibes.
I've posted in Ask Kev if anyone else is interested. This has got me worried. http://www.xt660.com/showthread.php?t=12241 |

I had the same problems since new for over 16000km or 1.5 years, and I had done the re-torqueing of various nuts and bolts, then came across the above. I had to combine that with bar-end weights to give me the best result. Still it wasn't noticeable immediately after installation, it took about 100km or so for everything to settle in, and it does seem it works. Now it's the smoothest since I got the bike. What also came to mind is my dealer did an adjustment to the injection and the exhaust. I am not very technical, but I believe it might have to do with the way the airflow/fuel injection relates to the engine performance. I suppose the purpose of a PC of smoothing out the engine has something to do with this vibration problem, instead my dealer has the equipment to do the modifications directly. Mind you, the result still wasn't great after such adjustment by the dealer. The best result I have is from the combo of vibranator and the bar-end weights. Hope it helps. |

Do you know who has made those bar weights? I would be interested in getting ones because I also have a Magura handlebar with Acerbis handguards so I can't use the original weights. Jami |

Yes I have seen it. Because my bike has been so smooth for the last 13000 miles the vibes are really noticeable and felt through the seat and footpegs as well and make the bike almost unrideable above 3500 revs . |
My sons and I have had the same type of vibrations and have retorqued the engine mounting bolts with lock tight. Have double bolted mine where possible and it has improved the vibrations tremendously.
