Vibration and Brake discs

[BigAlan]

- did you get to ride the Dealer's tester unit ?

- did the tester also generate the vibrations that you speak of at the 4,000 rpms range ?

- did the dealer/principal's rep acknowledge the vibs ?

.

- the reason for asking is that I am in the midst of breaking in my 2012 GTR and am doing it by the book (and it says to keep her below 4000 rpms for the first 800 kms). You can imagine how difficult its been so far to keep the throttle checked ...  so have learnt to keep it nicely at 4K .. and there are absolutely no vibrations at all from the machine.

- hope you get to resolve your issues there.

I got to have a test ride before purchase, but not KAwasaki's own personal bike
Kawasaki say they can feel the vibraiton but think its normal
Everybody concerend with Kawasaki reckon there is nothing wrong.

Initaially when i purchased the bike i had excellent riding, no vibes and could have not been more happy, now i get the vibes and nobody at Mr K seem to care.

I would start by doing the easy things:

Torque the header, exhaust, tank before attempting the engine mounting
Heavier bar ends, or adding a washer in between bar end and grip
Grip puppies are also known to help

Funnily enough i put a washer in between the end weights last night, and i have also ordered some grip puppies, we seem to think alike.

As for the torquing of stuff i am not so sure.

- would you recall whether anything was done to or happened to the machine between the time it was vibe-free to your situation now ?

- was the bike broken in by you ? (non to sound judgmental or anything) - if it was broken in by you , was it done by the book ? The reason I ask is that there is a pretty stark warning contained in the manual about breaking it in properly, if not you will have a "broken down bike" ( manual's actual words ).

Funny enough, this breaking in lark was mentioned to me when I complained about 'vibes'..... my answer was that in 2012 its a pretty piss poor engine that has to be run in like an old Norton...... the whole maintanence thing was a bit of an issue for me, I have to say.

Good people on here gave me advice about cleaning discs and calipers and the like... thas OK ... but this is supposed to be a touring bike and one souldn't have to spend every other week buggering about with the spanners.... again tis 2012 and if Kawasaki can't build a bike that can go long distances without someone waving a tool kit at it, then they need to go back to the drawing board and start again..

I can say that i rode the bike almost exactly as asked to by the selling dealer, in fact i did 550 miles in the first three days and it was so good i banged on about it to everybody within listning distance.

The first 2300 miles were perfect, then i had a vibration from the front disks right at the start of a long trip across Germany so could do nothing with it until i returned, which by that time i was getting numb hands, and unitl i try again on a long run dont now if the washer trick will have helped.

I get a vibe from mine but only on the righthand.
Even then not every time I ride.

[Kwikasfuki]

I get a slight vibe on mine, and only noticeable on long rides at speed. Otherwise fine.

I know when I replaced the exhaust and forgot to torque the tank correctly, both gave some vibes.

[BigAlan]

Kawasaki have asked for my dealer to retorque the engine, ie undo the lot, lift the engine up slightly then reseat it and bolt it up in the correct sequence etc.

Next thursday, so will give it a blast after that.

- to be honest , Kawasaki do seem to be , at least , trying.

- hope you get to sort out your troubles.

  it's frustrating though whilst the efforts are being made to correct a problem

Patience is a virtue

Went to Demon Tweeks open day on Saturday and spoke to a really helpful guy on the Brembo stand. Anyway he can supply replacement discs at about £350 a pair, but he can't understand how the discs warp and reckons road use cannot warp discs. He assured me that there is something else to look for and feels he would struggle to warp discs on a track . Break, shatter wear out yes, but warp never. He suggests looking at sticking pistons as a starting point or other caliper issues.
I have no idea myself, this is just his opinion that I thought I would share with you. Always interesting to get another "experts" point of view.

Ok an update on the vibration issues, eventually I took it back to the dealer who this time lifted the bike up and released all the engine bolts, then reseated it and torqued it back up.

Bliss, now the bike is back to what it was when I purchased it, Simon at Kawasaki and the lads at Premier bikes have been a great help in getting this issue sorted, I have also fitted some grip puppies and now can't seem to get my arse off the bike, the trips seem to get longer and longer.

That is really fantastic news!! Good job being persistant! 

[Kwikasfuki]

Glad to hear it's sorted. There was another Alan in Spain with the same issue which was resolved by the torquing of the engine mount.

brill news Alan glad its all sorted
