    Then allow me to convince you. Get down on the right side of the bike with a flashlight and look up a few inches inside the frame, to the rear of the cylinder head, and find the small accordion-boot-covered plunger attached to the stepper motor. Cycle the bike's ignition on and off, shine the light on that plunger, and watch it move in sync with the faxing sound. From that position it also becomes quite obvious that the sound is coming from that location.

    Try it, you'll see.

    I'll also add that for those who have the stalling issue, giving that plunger a little squirt of WD40 and cycling the ignition will solve the problem. It happened to me a couple of times on my Labrador/Newfoundland trip this past summer, and the WD40 cured it until more dust accumulated.

    I disagree, as well. I can get my ear within 4" of mine and it makes no noise and moves for a just a fraction of a second. Also, my "fax" noise comes from up toward the front of my fuel tank.

    Once it warms up a bit, I'll set my tank sideways on the frame and go through my previous start/stop sequences. I'll find it, one way or another.

    +1 While diagnosing my own idle issues I saw this with my own eyes.

    Perhaps, but you're talking about a completely different model bike. I can't speak to how it works on the Tiger 1050, but I'm not bullshitting about how it works on the Tiger 800. I've watched it in action several times. Obviously so has Mercury264.

    I'll check it out Mark, but if it is a common noise to all of the newer Triumph line, including those without stepper motors, then it has to be something else.

    Mark, I will need to do the WD-40 treatment I guess. I am having serious stalling issue especially when the bike is hot from elongated time of 2nd gear riding. Has anyone put up pictures of this? Also, what else should I be doing to counter this stalling issue.

    I don't know shit, but my dealer said its resetting everything for proper start up. Good enough for me.

    Tek, remove the tank & airbox. The stepper motor arm needs to be clean & lubed. Here's some pics

    Make sure you've got the latest ECU tune in it. The tune in mine has anti-stalling properties like a diesel. So much so that it'll tickover up a 1in5 hill in second gear!

    I have not heard the same noise on my Speed Triple and Sprint.

    OK, so when people say to remove the arm and lube it, what exactly are you talking about :ear

    From the pic it appears the little nut bottom right has been remove to pull that shaft out - is that correct ? If so, how did you get that bolt out with the throttle body in the way - as per the pic ?

    When I was diagnosing my stalling issues, I wanted to undo that nut to get to the shaft and clean and lube but IIRC, I couldn't get it out due to the throttle body being in the way.

    That pic is all that was done. I cleaned up with cloth & compressed air. Lubed the stepper arm & throttle roller.
    You don't want to screw up this gap

    My wife's Street Triple makes the same noise. :deal Must be the 675s not the 1050s and since our 800s are based on the 675???

    When we shut both bikes off they race to see which one can fax home first. :lol3

    Thanks Rob - so you didn't actually remove that nut I mentioned then ? The one at the end of the shaft - it just looked like it had had a spanner on it at some point.

    I did fix mine by pretty much doing the same thing, I was just curios if I was missing something.

    I thought you just pulled the rubber boot back and spray some dry lube in there?

    After a dusty few days of riding the bike developed the stalling issue. Tried power washing, did not help. Sprayed the stepper motor area with WD40, the bike fired up with a rough idle which made me think I just F it up. After about 30 sec the idle was back to normal and no more staling. That was 14,000 km ago.

    The motor oil must last a lot longer than WD40. :lol3 :1drink

    My Tiger 1050 and Daytona 675 have/had the same noise. It's supposed to warm up, toward the end of the week. I'm pulling the forks for servicing and am going to dig into the noise source. I'll report back.

    Just throwing this out there for the sake of discussion...

    Every other bike on the planet just has an idle adjustment screw. No stepper motor. Has anyone considered removing the stepper motor and installing a traditional idle stop?

    I know it would lose that cool anti-stall feature, but it would eliminate all the seized stepper motor problems.

    Again, I'm not saying the stepper motor is so bad it needs to be removed. Just proposing a "what if" question.

    This is odd because the 1050 does have a stepper motor system the same or similar to our 800s. http://www.worldoftriumph.com/trium...lock_01=&block_02=1000371-1-2&block_03=610301

    The 955 versions have an "Idle Air Control Valve" (IACV) instead of a stepper motor. http://www.worldoftriumph.com/trium...r.php?block_01=&block_02=302546&block_03=9785 Different system altogether.
