    Sometimes when riding and I stop at a light/stop sign my bike will idle under 1,000 rpm and shut off.
    Does anyone have a reason for this to happen? A fix?

    Is it brand new? (low mileage)

    it is a 2013 S10 w/20,000 miles on it. I "baby" it. It is mainly ridden to work and back home. I bought it last year with 18,000 miles on it. Not abused at all.

    Ok. I wanted to eliminate the "new bike" scenario first because the Tenere is one of those bikes that improves quite a bit over the first 4-6000 miles. Especially the Gen1 bikes.

    So, if I was experiencing your issue on mine, the very first thing I'd try is verifying the throttle bodies are in good sync. Again, the Tenere is strongly influenced by throttle bodies that are not working together in harmony. Especially from idle>2000 rpms or so.

    And you would be shocked at how much better that bike behaves with the ecu reflashed.

    Finally, if you are going to "baby it", I strongly urge you to religiously use a fuel additive. Actually, I suggest it regardless of how you ride. Some Teneres have been discovered with substantial carbon deposits.

    Good luck

    Couple of quick questions:

    Does the battery seem weak? If it is the original battery, it could be getting weak, and this bike does some weird stuff with a weak battery.

    What was the last thing that was done to the bike.

    I Am asking as this usually happens to new bikes until they break in, but yours is not new.

    Thanks snake. I have been thinking of a flash. I will look into the TB`s.

    New battery installed 2 months ago.
    I did run the bike with low octane fuel for a few tanks. It has higher octane fuel the last couple of fills.

    Last things, dealer did a recall.. wiring for head lights.
    I installed a can, Yoshimura.

    What snakebitten said. Fuel additive is something I'm going to start using regularly. I don't rev this thing often enough to make me feel there's not going to be any carbon buildup and I'd rather play it safe.

    The reason for the strong opinion towards the fuel additive was a couple of years ago a few popped up with surprising and alarming amount of carbon deposits. These are guys that take really good care of their bikes. And we, collectively, had gotten our Super Teneres all that the same time. (First arrival of about 1500 bikes to the USA)

    So it was a bit of a shock.

    In most cases, the instructions were 1. Don't lug this thing. It's built as a rugged as a tank. Rip on it every once in a while, at least. 2. Add the fuel additive to combat the various potential causes. (There are a few)

    The result, a few years later, are some high mileage bikes showing nice and clean valves. So it's a cheap and relatively painless preventative. My own was recently shown to be spotless when a couple of valves shim adjustments were performed. (First time a valve clearance was adjusted. Just short of 50,000 miles)

    And yes, I promise you will have ZERO regret spending the few bucks to get your Gen1 ecu re-flashed. It makes the bike run so much better that you finally realize how poorly the fueling was all along. I don't shy away from using the word "stunningly" improved. (I also have never seen a Gen2 reflashed customer complain that the improvement was subtle. Although there are a few Gen2 fellas convinced it isn't warranted. None that felt that way after doing so :) )

    Again, good luck!

    I have a 2016 and it died on me a few times when the bike was brand new. ( Below 1000 miles I think) It hasn't done it for quite some time I only have close to 2000 miles at this time, but it does seem to run better as the miles increase. I probably need to start using a fuel additive as I don't bring the RPMs up enough to knock off any carbon build up. Are you just using any additive that retards carbon build up? Thanks

    I grab a handful of the single-serving size at the Yamaha parts counter when I stop by. That way I don't have to measure. Or at least I don't! Lol
    Yea, probably not the least expensive route, but I'm old, worked for decades for this era of my life where when I'm mounting up on a horse, I just enjoy.
    Oh, it's a yamalube branded little bottle.

    EDIT: Just dumped a bottle in the tank and noticed that I hadn't noticed a label change at some point in the past. Still the familiar black bottle, but named "Fuel Medic" now, instead of Yamalube. Probably always was the same product, I suspect.

    I suggest throttle body sync/adjust and CO adjust.
    My bike would hiccup and sometimes die just off throttle - the lean condition at idle might be causing your problem.

    Sync:

    CO adjust (mine is set at 6 - easy to set):

    I made a my own sync tool (20 feet of clear tubing I had laying around + trans fluid) but a better solution:

    Also check to make sure that your idle speed is correct. I had an FZ6 that did the same thing and the cause was low idle speed. Bump it up a notch and that may take care of it.

    Hi guys, I bought a 2013 Super Tenere last May. It had 2640 miles on it and the original owner installed a Bazzaz Fuel Controller along with a Yoshimura RS-4 exhaust and BMC high flow filter. The bike was stored in the garage and he would occasionally ride it. He ended up buying a Goldwing because his wife did not like sitting so high on the back when they were touring.

    I flew to Asheville, NC to pick it up and rode up the Blue Ridge Parkway to D.C., NYC onto Maine. I returned to Texas by riding the backroads of NH, VT, NY, PA, MD, WV, VA and TN. From Tennessee I rode the Natchez Trace Parkway over to LA into TX.

    On two occasions during the month long trip the bike would accelerate on its own or just turn off at low RPM's, otherwise it ran excellent. Since returning home it occasionally repeats those behaviors. I took it to the dealership and the only thing they could find was a throttle position sensor was off. They reset it and so far the problem has not returned.

    The service manager told me the Bazzaz may be an issue and that fuel controllers are not really necessary on newer bikes because the onboard computer will adjust to and exhaust and filter modification. He said its one more point of failure on an otherwise great motorcycle. He also suggested I use Star Tron fuel additive since I ride in stop and go traffic and may have had a couple of questionable tanks of fuel on the trip.

    Any opinions as to whether I should remove the Bazzaz? Also, what is ECU re-flashing, is that something the dealer can do?

    Thanks guys, I'm glad I found this recent thread!

    Here's a picture at the end of Long Island just before I boarded the ferry to CT.

    The bike is running terrible now. Hard to start, idling under 1000 rpm and turning off constantly. I've called three different shops and no one seems familiar with the Throttle Body Sync procedure. Any advice or direction on how I can do it myself would be appreciated. Especially in regards to the syncing process, the harmonizing linked above seems to be very hard to find these days, any alternatives?

    You can do it yourself. Google Yamaha Super Tenere Forum. They have all the how to info you will ever need. Bike specific website. Very good source of information.

    This could be the high/low idle and stalling issue which has several huge threads on the tenere forums. Try popping the right cover off and moving the wire harness around while the bike is idling rough, Yamaha has apparently replaced several wire harnesses outside of warranty and cured the issue...

    Mine did this once, died at several stops, idle below 1k... I did not take a scientific approach because my idle came back when I got home, BUT.

    I replaced the vacuum cap on the TB. (it was cracked on the outside)
    I synced the TBs.
    I re-routed the AC gen wires away from the main wire harness.

    During this work I inadvertently moved and wiggled the wire harness.

    I have been waiting for it to come back, but 500+ miles an no return yet.

    What did y'all use to sync the throttle bottles? I've read some people just turned the screws out 270° and others used a Harmonizer, this is hard to find now and I'm not sure if there's a good alternative.

    I really don't want to start turning out screws set from the factory without a way to measure changes.

    This is my first non-carbureted motorcycle. So I feel a little out of my comfort zone on this.
