    i just completed 20,000 KM in south america, and i am still having issues with the idle. i likely need to get a decent tank of fuel, and have the throttle bodies adjusted. then we'll see where we are at. the verdict is still out.

    Did you try opening up and closing rapidly the throttle when the Fax sound is being made aprox 30 seconds after you turn it off..?

    no, i haven't. what is that intended to accomplish. i wanted to get a service first to insure the throttle bodies are still in sync. lot's of bad gas in SA.

    Hi all,
    New member and new owner of a Tiger XC. She's registered July 2012 and has only 1,600mi on the clock.
    I experienced an engine cut-out last week. I want to call it cut-out rather than stall as the latter implies operator error. It was not.
    I was travelling at speed when the engine cut out. I have been following the threads here but I have no idea what "mapping" is. I imagine that, if Triumph got to the bottom of the problem around Jan/Feb 1012, my bike should have been covered.
    Any help at all would be much appreciated.

    "Mapping" is the software that controls the fuel injection system. As your bike is still under warranty, take it to the dealer....tell them your issue....and have them "up-load" the latest software map to your motorcycle. I won't take long. That should solve your problem.

    If not, then you probably have a dirty "stepper motor". Do a search on this site and it is explained in detail. But this is probably not your issue.....unless the bike has been ridden off-road in dusty conditions.

    Hope this helps.

    The stepper motor arm & throttle roller need lubrication. If they are bone dry, then it acts like its dirty & causes stalling & no idle. "Traveling at speed & the engine cuts out" sounds like a loose battery terminal. Check the easy stuff & take it to the dealer.

    Thanks both for your help.
    There's a dealer near me here so I'll get her looked over. I noticed today that she didn't want to start a couple of times too!
    If it's a warranty issue I expect the re-mapping would be free?

    Clarification:
    A cut-out, while the bike's motor is under load is a different problem than the stall problem, WHICH WAS NOT RIDER ERROR. The stalling problem happened when you would start twisting the throttle, irrespective of having the bike in gear or not (bike not in gear, no room for rider error). The stall problem had two main sources: 1) fueling map, and 2) stepper motor. Let me rephrase that, both were related to the stepper motor actuation. One of them was a software issue, the other a mechanical issue.

    My XC also wouldn't idle after a very dusty 3000km ride in Namibia. Will definitely lube my stepper motor! Thanks

    Short term 'on the track' fix is to start the engine, switch it off, wait for the 'fax' sound, which is actually the stepper motor components activating themselves in an attempt to self clean, start again, and go through the process several times. When you get to some tools etc, rip the tank and air box off, spray some cleaner over all the components and then some dry lube. This prevents collecting too much dust too quickly. We used this process for an XC recently and it worked a treat.

    Most Aussies now clean these components whenever the tank and air box are off as a preventative measure. Just another part of regular maintenance.

    Just add the procedure of lubing the stepper motor and linkage to your maintenance schedule and you shouldn't have a stalling issue. Any time the tank is off, clean and lube it with a dry lube.

    Not to disagree with some, but lubing the stepper motor is just a bandaid. The design is not good and can cause serious issues over a long dusty haul, example:

    My brother rides a tiger 800xc and loves it. We ride a lot in Colorado where many trails are very dusty. Started having problems after a couple thousand miles, so took everything apart and cleaned and lubed for the CO backcountry discoverer route. Perfect, fixed. All was fine until we hit a very dusty section. At thia point a couple hundred miles into dirt ride.....Got to a stopping point for gas, shut off the bike...bam wouldn't start. Cycled the bike over and over and simply to dirty. We had brought the tools to disassembly and get to the stepper if need be but a lot of little parts. Instead used a bunch of wd40 and sprayed from the right side ....cycled a couple times and it worked. We had to do this more than once over a 1,300 (600ish dirt) trip. Moral of the story cycling the stepper does not always work, lubing before a trip doesnt work if dusty....carry wd40 to spray from the side.....dumb fucking design.

    If your out in the woods and don't have spray lube or all of the tools, this problem will, I repeat, will leave you on the trail. Cycling works sometimes but I witnessed this problem many times now and it doesn't even work 50% of the time.

    I agree, but what's the alternative?

    We can bag Triumph for poor design, but they're not going to fix our bikes.

    I'm no rocket surgeon :D, but I find it hard to believe the collective ADV hive mind can't come up with a solution to keep dust out of a linkage, or at least minimise it?

    Anyone? :ear

    Yeah we have been trying to figure it out. The first lube we used when taking everything apart was good non dust attracting lube...but the wd40 well....in the end, neither was great.

    We are going to revisit it soon because want to do some long UT and AZ bdr rides this summer. I've been looking for anyone else that has enclosed it in a breathable dust proof sake..." Put a sock on it".

    Some folks have replaced the unit with success, but I don't understand that. Unless theirs was completely dead.

    No luck yet though.

    Ride smarter. Stay out of the dust wave. Lead the ride.
    It's possible to have a bad stepper motor. Mine was replaced under warranty, lubed the throttle roller & stepper fist area. 13,000 miles later (at least 2,000 dirt) & no issue.
    FYI, I never had a problem starting my T8. I did have to give it some throttle to make it start, but it never stranded me.

    hmmm...so riding a dual sport in dust is 'dumb' riding, gotcha. Be sure to have him keep it in the garage.

    Checked this and no issues with the actual motor, just dust build up. I know a lot of it has to do with the type of dust. For instance dust from decomposing granite or gypsum (very common here), is very sticky compared to dust from gravel trails on the east coast. Same as Utah dust...once that sandstone dust has attached to your bike....you now have a different color motor.

    Now we ride a lot of dirt on our big rides 75/25 (dirt/pavement) average and it is then over a thousand plus miles of dirt, over a 7/10 days (without a rain storm to wash) that problems come about. I bet we have had this problem at least 20 times. It is predictible to the point that we don't turn the bike off when stopping for a quick 5 minute stop. My guess is your 2,000 miles of dirt had 10-20 bike washes along the way...big difference.

    Will report back how a sleeve works later on.

    It would seem to me that you could use an old air filter of some kind and cut it into a sock shape, oil it and make a cover to wrap from the bellows to the actuating arm

    That may well be a viable solution, but I must admit that I don't know exactly which part of the linkage causes the problem. :ear
