Hi guys,
Been out for a potter on the bike and have the following problem:
When coming to a roundabout (or something that requires a measured approach) I ease off the gas and hold the throttle just open. The bike revs are in the 3,000 range and slowly falling as I approach. Every time I do this the bike lurches forward as the revs suddenly drop to about 2,000 and then lurches back as the revs shoot back up to 3,000. This all happens with no accelerator input from myself. I find this particularly frustrating when trying to maintain a steady 30 mph which equates to about 3,000.
I have to pull the clutch, drop the revs and then come back up which seems to reduce the problem.
This problem is more exaggerated in economy mode but still there in normal.
It is not comfortable at all and makes me sound as though I'm opening and closing the throttle every second.
Any ideas what could be causing this?
As I have said in another thread the bike is 2010 with 2500 miles and fully serviced.
Hope someone can shed some light on the above as I will have to take the bike back to the dealers (bought Saturday 6th October) and would like to be able to communicate with some prior knowledge of what the problem is and what needs to be done.
Kind regards,
Sharpy
mmm , thats a tough one to diagnose, my bike does not do that , and from the way you describe it , maybe its fuel management/ecu/ settings ect . does nor sound anything basic like a sticky throttle. Best get one of the dealers mechanics to test ride it for you.
Have your dealer check the throttle position sensor .. It can cause similar problem
Not heard of that before but would imagine it is fuel delivery / sensor related ... back to the dealer and let them sort it ... :wink:
Cheers guys,
Will give them a bell tomorrow.
It's a pain the :asshole: as the dealer is about 70 miles away from me.
I'll keep you updated with what they suggest. Either way it's gonna cause me hassle and a wasted day.
Sharpy
Do you have any means to contact the previous keeper, perhaps ask them if it was evident when they had the bike. Its always possible the dealer has interfered with something un-intentionally while perhaps prepping the GTR. Long shot but worth looking into.
Not a bad idea but I don't have any contact details to hand.
It can't have done many miles since the last service, maybe they tweaked something?
It does feel like a fuel issue and the suggestion that the ecu or mapping is out makes sense to me.
new bikes have all sorts of sensors, lamber, o2 readers ecu settings , christ knows what else, can the gtr be hooked up to a diagnostic code reader like modern cars ?
Quotecan the gtr be hooked up to a diagnostic code reader like modern cars ?
Yes it can. Although every time Mine has been hooked up to The Computer, it never spat out any decent or useful information... I alwas asked them to look at the FI error, but they can never find any trace of it in the error log.
Maybe this will be diffrerent.
Hope you get it sorted out - sounds a bit dicey to me...
TBH, I've not heard of that one before
My first reaction was that its something to do with the fuel and/or fuel mapping ~ possibly air feed and mixture, as its sounds a bit like an over-run issue
Best let the dealer sort it
Well took the beast back to the dealer this morning.
Their technician took it out for a test ride whilst I waited hoping the problem would show up for him.
I didn't want him coming back saying it was okay and therefore an intermittent problem.
He came back and said "well that ain't right, it's dangerous" - first hurdle. Out of the way.
He hooked the bike up to the diagnostic thingymabob and got a fault code for the rear wheel speed sensor.
One of the guys who worked at the shop had a GTR1400 so they whipped his sensor out and put it in mine..
Hey presto.......problem still there!
They are now scratching their heads about it as Kawasaki Technical advice were "out all day" and could not be contacted.
I've had to leave the bike with them and wait for an update.
I agree with the general comments above that the issue is likely to be fuel/air/mapping/ecu.
The dealer gave me my old Z1000 to use whilst they fix mine.
I'll update when I get a firm answer as to the problem and the solution.
the bike must have been traded in with this problem, maybe thats why the owner let it go, which dealer did last service ? , contact them to see if they had tried to solve this one , V interesting , please keep us all updated .
Well at least the dealer has recognised the problem and seems to be cracking on with it ... let us know of any updates :smiley:
Sharpy I take it you've had the GTR since Saturday 6th October. You don't want to be lumbered with a lemon, give them a week to fix it or bin it and get one from elsewhere. You can't be expected to be travelling 70 miles each way to get them to look at issues with the bike.

I know a person who had similar problem it took the dealer a long time to discover the problem and at the end it was the throttle position sensor. the code is no. 11, have them check it

good advice, tell them to collect the bike , repair and deliver back to you in 5 days or give you a refund
Crumbs!
Haven't been on the forum for a few days and looks like members are as riled as I am by this.
Haven't heard anything from the dealer yet and will have to phone for an update in a bit.
Must say that I'm not too impressed so far.
When I took the bike back the owner/manager who did the deal didn't even acknowledge me when he walked past me in the shop a number of times. He knew the problem I'd had and that I'd had to take time off work etc to get the bike back.
I had to bite my tongue as I just wanted them to get on and fix it with no side issues to cloud the matter.
Believe me I'm not used to biting my tongue and I would have rather liked to have a very frank discussion.
Will update when I know more.
Thanks for all your interest and advice!
Just made a quick call to the dealers who were, spookily enough, just about to call me.
The update is that there is no update. The problem is still there and they have tried swopping parts out from another GTR to see if that solves the problem with no joy.
Not getting a good feeling about this as the guy said once they found the problem they would contact Kawasaki to see what they could do to help. The bike is out of warranty by the manufacturer but is covered by a 3 month dealership warranty.
probably why such a low milage bike was traded in, id encourage the dealer to update you via email , just so you have proof if anything goes pear shaped. as i said before , give them a time limit before you get a refund
Reject it now, don't be disheartened by this experience, you have just been VERY unfortunate. Bin it and get another from elsewhere.
- since they're at the "swapping to see" state , what they might want to try is to swap out the entire throttle body with their other gtr (alot of work , this).
- on the gtr , there are the primary throttle plates operated by cable from the grip , and also a duplicate set of secondary throttle plates operated by servo by the bike's ecu.
- any failure of these parts may cause the lurching at small throttle openings.
- if its an injector fault or a fault with the TPS , the swapping of the TB will also show it up.
- good luck.

That would be my advice also....don't throw 'good money after bad' as they say
Got a phone call yesterday to say that the bike is fixed :clap:
Turned out to be the throttle sensor. I'll get a full update when I pick it up this morning.
Mechanic has taken it out a few times since identifying the problem and it has not happened since.
Just hope the weather holds as I plan to take the long route home.
Was starting to think about asking for my money back but if the problem is solved I'm more than happy to keep the bike and get on with putting some miles on it!
Thanks for all your interest and advice: very much appreciated.
I wonder if the owner/manager will acknowledged / speak today...... I suspect his customer service skills will continue to be :shit:
I guess I just have to accept that I was so lucky that he let me buy the bike from him. :nono:
The guys in the shop have turned out to be great with an interest to resolve the problem.
I'll post later with an update on how the bike went on the way home.

You were all over it mate!
Good call.
Fingers crossed its now fixed.
That's a good result Sharpy, I'm sure you will have a great ride home with a BIG grin on your face :clap:
Best to keep the visor closed when riding your GTR... Stops the flies sticking to your teeth when you're grinning ear to ear
flies are high in protein .. that's good for health .. :mfr_lol:
great result and yet more learning for us all :clap:
:banana: :banana: :banana:
Bike all good. No longer like riding a bucking bronco.
Once again ; thanks for all your input, advice and help.
Good result that Sharpy, so glad you went down the understanding and sensible route, rather than the one suggested by some on here of :gun_bandana: :gunsmilie: :hammer: :2guns: :death: :hang: :taz: :fuk2: In life I have always found that it's nice to be nice, and try and see things from someone elses perspective. All you have to do now is enjoy the bike, and I'm certain that you will. :banana: :smiley:
Good news that. Enjoy the ride

Sharpy, congratulations on getting it fixed. Now go enjoy your new steed.
