Unsolved xt660z tenere problem
 

Hi to all.
I 'm a new member so I would like to apologise in advance for any mistake (post in a wrong category, etc). I will improve myself with time.
I 'm an xt660z tenere owner (Nov '10) with approximately 8.700 km so far. The problem I face is that while I 'm holding down the clutch to change gear the engine shuts off occasionally and as you could imagine this is a very dangerous situation. That happened about 10 times (fortunately while I had low speed and the road was empty) before the 5.000 km service and I managed to start the engine again before releasing the clutch. When I went to the official service store (5.000 km service) I told them about the problem. They answered that this could be happened either due to TPS or idle speeding wrong adjustment. After the service (I don't know what they fixed) the problem appeared once and I went to the store again to adjust this time the idling speed (it was about 1300 r/min) because I was preparing for a long trip. During the trip I had no problem but yesterday it happened again (driving to my work) while I was taking a turn, and that was really shocking. The problem occured always during the changing gear process and right after holding down the clutch.
Given the fact that the bike is new (in guarantee period) I would like to ask your opinion and your advices. Has the same problem been reported for the xt 660z and what do you recommend about it?

Sounds to me like it might be something to do with the clutch switch? I'd press your dealer to get it sorted.

Actually my first port of call would be to check the bike idle speed by ensuring the the engine has a steady tick over between 1450 - 1500 rpm at shut throttle. Other than that you might require a fuelling fix, by means of altering the Co2 values in your A/F mixture, in which case if after you've checked the idle speed, things won't improve then please send a pm to Kev who will point you in the direction of a few threads that can help you with that issue.

In any case don't despair, lots of helpful people here to lend their support every step of the way.
Cheers

Also check the side stand switch ,that can cause the bike to stall when you engage a gear ,i dissabled mine with a piece of wire

I had the same problem on my SV 650.After checking the bike over I noticed that the clutch adjustment tensioner on the clutch lever had come loose and the clutch cable had lost tension meaning that the clutch was not disengaging properly.Once I tensioned it up again it was fine.It is always good to check the simple things first just in case.

I agree that first look must be taken at simple things. But, I wonder... shouldn't have the problem occured more often (if not the most of the times) if there is something wrong with the clutch adhustment?

Nothing wrong with the clutch adjustment, I have had my XT from 04 to 08 and never even had to touch it or adjust.

Have you checked your tick over yet?

The tick over is approximately 1300-1400 r/min. I have already increased it to about 1450 and I have to wait to see if it happens again.

I also want to thank you all for the prompt support

Thanks, don't mention it, that's what we're here for.

Thats amazing Capt Moto diagnosing a bike without seeing it.How do you know that there is no problem with clutch adjustment.These things can be marginal and are always best eliminated as it only takes 2 mins to check.If the knurled adjuster on the clutch lever vibrates loose then the adjustment can change and the clutch may not fully disengage contributing to cutting out or stalling when the gears are disengaged or selected.Also XT's have this adjuster underneath a rubber cover so it is not something that you would see unless you specifically looked for it.All views welcome.

I detect a hint of sarcasm. Look pal, of course I can't give you a definite cause of the problem without seeing the bike, I am not a magician but you know what funny man, we've been dealing with these bikes and their common issues almost since time began.

As for Kev what he doesn't know about the XT's its not worth knowing, personally I don't have ANY mechanical expertice or knowledge, as I am more of a bike abuser than a mechanic but, having owned the same bike for long enough to know what is likely to go wrong and also having run this forum shoulder to shoulder with someone with the knowledge and experience of Kev, I can confidently say that working by eliminations and suggesting to check the most common faults first, would help myself and Kev to figure out what is the cause and then suggest a solution, bear in mind that the OP has stated that his mechanics couldn't see anything wrong, if they are only half good they would have spotted an insufficient clutch "bite" and let me also remind you these clutches have self adjusting plates that even with the slightest of "play" in their action will eventually do what is designed for them to do and that ultimately in our experience, problems with clutches on these particular bikes have been as rare than hen's teeth.

Another vote for the side stand switch !!! Check it is making proper contact with a multimeter or if you can't just cut the wires and join together then insulate with tape.

Sorry your upset I don't think it's very fair to just dismiss my suggestion as it is not impossible for this to be the case.If you think it is unlikley then fair enough,according to Kev everyone's view is welcome pal.

No worries mate I was not upset. And yes all views are welcome, so keep them coming. :hippy2:

FINNALLY somone having the same problem, the dealers pretty much tell you your making it up when you tell them but now i can show them this thread and tell them to sort the ****er out!

Don't get suprised. The same thing happened to me at the official service store here in Athens (Greece). When I asked about it they affirmed that this kind of problem hasn't been reported. The forums reveal another truth.

We have seen this problem since 2004 on all XT variants, bike cuts out as you blip the throttle on the down change, 90% of the time lifting the idle speed to 1500 rpm fixes the problem, 5% is from riders adjusting their Co to rich which can also cause the bike to cut out & the other 5% is unexplained.

So far I have not seen one problem rising from a failed or incorrectly adjusted clutch switch. The clutch switch is there to let the ECU know that the clutch has been pulled in when trying to start the bike in gear, the clutch switch also supposed to tell the ECU when the RPM is below 2000rpm to adjust the ignition timing to assist the idle speed which does not seem to work on the XT660's. On other bikes the clutch switch can be used to lift base idle speed by dampening the falling idle speed before base idle via a stepper motor.

Set your idle sped to 1500RPM when the bike is at operating temperature & let us know how you get on.

When I asked about it they affirmed that this kind of problem hasn't been reported.[/QUOTE]

Kev, to avoid any misunderstanding, I asked particularly about tenere.

I 've already set my idle speed to 1500 and I will keep you all informed if the same thing happens again.

The XTZ has been reported to me many times cutting out, the motor & ECU is exactly the same as the XTX & XTR but does run a different firmware level in the closed loop on the Z.

On the XTZ which have been cutting out I have found the idle speeds set to low & or Power Commander fuel map adjusting the A/F ratio below 2000rpm causing the cutting out.

Have a look in the ASK KEV section you find a whole lot of topics covered in great detail which are not covered in the open forum.

Yes, I don't think clutch or sidestand switches are the culprits here. You have to put the sidestand down quite a bit before it cuts the engine, almost all the way.

Hi there,

I bought Tenere recently - 3weeks old and have had the same problem, two times so far :(

I am about to od my first service @ 600miles and wanted to mention about it to my dealer but if this is just the idle speed (as you advise) I can give it a go but....where to adjust it?

Many thanks

I had same problem with 5000 km. I lifted idle spead on cca 1500-1600 rpm and problem disappear. Today I have 45000 km.

@bone: Does this happen when you gear up, or down, or both? I noticed that, while gearing up, my boots occasionally touch the "helper" of the side stand (don't know the name of it). Mostly when i stand on the pegs, the rotation of my foot makes my boot touch the side stand. It is not enough to move it that much so the side-stand-switch turns off the bike, but maybe your switch/boot/anatomy is somewhat different ;o)

Gear down (in my case)

If you've just bought the bike from a dealer, take it straight back to the dealer and get them to sort the problem under warranty. DO NOT do anything on it yourself as they will then argue and wheedle out o anything warranty related with it.

Down gear in my case too.

Hi all,

apologies for reviving and old topic - I just bought a 2009 XT660X and have the same problem. Adjusted the CO value up from 12 to 20 and set idle to 1400-1500. The bike seems to have a K&N air filter and a full exhaust system from PIPE WERX.

please advise :((((
