[Sahagun]

Thank you again. I will be sure to tell the mechanics and will post the results here tomorrow !!!

Best regards,

Some people have managed to eliminate the vibration by adding a washer between the grip and bar end

Hello again,

My mechanics in Spain have now had my GTR 1400 for two days. I gave them the list of possible vibration causes, but so far it's still got the vibration and they don't know why exactly.

I hope they find it soon.

I will keep posting

Is it a vibration or buzzing? On which side and at what rpm? Diagnosing these issues can be hard.

Have they tried putting a washer between the grip and bar end?

[Sahagun]

It's more like a vibration and it occurs at 4,000 rpm irregardless of what gear I am in. The vibration continues all the way to maximum rpm.

This vibration can be felt with both hands, through my feet on the pegs and through my knees on the tank. In other words it can be felt all over the bike and it seems therefore that it's a vibration and not a resonance of some sort. The end result of this is my right hand thumb and first two fingers going completely numb after about 20 to 30 minutes. (And, no, my gloves are not too small !!!!  I made sure I checked this too !!!)

Yesterday, at the garage, they had not yet fitted a washer between the grip and the bar end. They will do this today.

Will continue posting with more news as it comes.

But this vibration feels like a very high frequency buzzing, that can be felt all over the bike.

Hope they find something today!!

Well that definately does not sound right!
I have got used to the minor vibration I experience through the right bar and the occasional numbness in my right wrist,but what you are describing is totally different. 

[Sahagun]

Hello Norman & Lonewolf,

I have just got the bike back from the mechanics - AND IT'S 100 TIMES BETTER !!!!

They re-torqued all of the engine mounting bolts which were about 3/4 of a turn too loose. Plus some other stuff - but the engine mounting bolts seemed to be the biggest culprit.

They also noted a slight uneven wearing of the front tyre, (8,500kms on it) and they adjusted the front suspension and damping back to the "standard" positions (5 clicks and 14mm)

The final result is that the annoying vibration has gone at pretty much all speeds - except those well in excess of legal speeds............but by then vibration is the last thing on my mind!!!

I have a 200km trip to make tomorrow......so I will give a better analysis afterwards.

Thanks to you all for your input and help.

Hi Alan,

I'm glad to hear the problem is resolved. I doubt the suspension or damping made any effect - I would be very, very worried if it did.

What tyre do you have on? If its the Bridgestone then you should be looking at replacing that with an alternative

[Sahagun]

I have the 021 Bridgestone original - but please see the PR2's thread.

Thanks

I was able to take the bike today for a much longer ride on both highways and two way roads with twisties - and the vibration (actually a very high frequency buzzing) has all but disappeared and makes the ride so much more comfortable and enjoyable.

It seems that the cause was the engine mounting bolts being wrongly torqued.

Great news for me !!!! Looking forward to putting on new tyres now !!

The tyres are almost due on my bike but won't be changing them till summer. Doubt I'll ride the bike at all during winter. Let us know how the PR2s go as I'm thinking of getting the same.

well glad i found this thread as i only picked up the bike a week or so ago and in the last 2 days have felt this buzzing /vibration ,was hoping it was sometyhing simple like torquing bolts especially on headers and engine mounts ,have just come from riding a cb 1300 so used to vibrations so wont panick to much.she due a service soon will get my mechanic to touque everything up aswell.Forgot to say mines a 08 with 9500 miles on it.

[Kwikasfuki]

I wonder if the 2011 models will have the same issues. Or maybe i'll just get a ZZR instead.

[Kawdolph]

Havent had a good read through the manual yet, but was wondering off hand does anyone know if theres a shaft adjustment on the gtr if so then this could be the problem for the buzz like feel.
