Sounds like an intermittent issues with Idling condition (off throttle) and I am also assuming that when you pull in the clutch, the throttle is also off.

Brain storming.

The YCCT system controls the throttle valves, opening it at certain angle to let in the right amount of air which the also release the right amount of fuel. ECU looks at MAP sensor vacuum readings, intake temperature, Throttle position sensor and determines the amount of fuel to release, and checks the O2 sensor if it did the right amount, under Close Loop conditions.

Areas I think the problem would occur are:
1. TPS sensor or its connectors and wiring associated to it.  The service guide shows how to check it.  Located at the throttle bodies.  Most likely source as this thing tells the servo motor how much to turn.
2. MAP sensor, or its connectors or wiring associated to it.
3. Servo Motor that drives the throttle plates but it being the fault is rare as it works when the throttle are turned.
4. Mechanical linkages that open and closes these throttle plates, are they loose, too much play, too tight...

Check item 1, maybe it is the wiring that tells the ECU the wrong information.  There is a post on making the bike respond better by adjusting it.

Lastly, is your throttle plates gummy with oily residue.  Would not harm to use Carb cleaning fluid to clean the plates and the surrounding throttle areas.  This is sticky stuff and sticky makes things inconsistent.

All my connections are good.  I went through when this first happened, checked all connections and added dielectric grease.

Havent checked the linkages as the throttle feels correct and responds as id expect.  It is just the times it does it, it happens and then will be fine for a while.

JoshMundy::: You just described exactly how my bike starting it's long journey of giving me misery for two or more years..
Intermittent stalls had to WAT from time to time to get it to fire up and feather the throttle to keep it running.
Then ran fine for a month or two then start's it crap again..
Nearly a year of High, low and stall bouncing RPM's at a light, i was about to push it off a cliff and clam it stolen at one point. :mad:
As i have been saying all along Yamaha knows much of whats going on just not recalling them.
Wiring harness so far has 99% fixed it, it does do the 900 RPM drop once in awhile but never stalled no more raw fuel parked in the garage smell.
And still pulling like a Mule with off the line Cheetah legs. ;) CROSS THE FINGERS?

Ya im not sure what I will do, but probably get it back into the dealership.  I just dont want to deal with them saying it needs the new ecu, as I highly doubt it is that but I have a feeling they will say if I refuse the ecu replacement then they have no other ideas as with the error codes it was throwing the book says replace ecu.

I own a 2015 non-es and it stalls at least once per tank of gas. Reading and working on a fix now. First time I have had a fuel problem on a Yamaha. I was out the other day with a BMW GS and a V-strom well the light turned green and everyone took off but me. They still won't leave it a lone. :(

This is a different problem.  Our bikes are not stalling and stumbling, they just are dying once there is zero throttle input and clutch is pulled in.   I can be doing 70 on freeway, let off throttle and pull in clutch, tach drops to zero.

I have had that happen to my bike just before it was parked for the winter. I went to downshift, when I pulled in the clutch to blip the throttle it died as soon as I pulled in the clutch. I just let it back out and the engine fired right back up..
I have just done a few loops around my subdivision so far this spring due to the crappy weather. So far it hasn't reoccurred.

Im my situation I can always pop out clutch and it fires up, but when i come to a stop or pull clutch in without throttle it will die again.  Then to get it to start you have to crack open the throttle a little, and then it will run but the rpms hang, never drop down even with zero throttle input.  It isnt until you turn off the bike, wait 10 seconds and turn bike back on that it operates normal

Did you observe if it does it in T or S mode or regardless.

I was in S mode a couple of times and when I pull in the clutch while cruising to a stop (throttle off), the engine died.  Bike was new then.  The Air screw 1/2 out from fully closed fix this kind of issues. Never had the stall since the screw adjustments.

From the observation that the issue fixes itself after the key is off and on again, shows a sensor issue, most likely the TPS, since it tells the ECU which angular position it is.

Since it is intermittent, it is hard to diagnose.  But do observe the environmental conditions when it occurs, such as wet high humidity, dry, cold, hot, etc ?  If it is a humidity correlated issue is likely that there is a short somewhere in the wiring or connector.  Also observe, if there were high vibrations or impact that can kicked in the symptoms.

Thanks for writing this Ramsey.
The Gen1 and Gen2 are very different with respect to hard start issues. The Gen2 engine is slightly different and it has a different ECU.

Never the less you need as well as your service manager to start calling Yamaha U.S.A.
Just mentioning wiring harness made the Yam tech mechanic bring a new one with him to New Mexico.
It started the same way and just got worse and more frequent.
Some guy on Youtube has the high idle while riding down the road, it idles at 2 to 3k with his hand off the throttle.
My 2012 did that and when you pulled the clutch in it idled at normal 1100 rpm, let i go and it jumped up to 2 to 3k again.
Was told by the tech the 2012 and 2013 was high on the list with this issue.

To the ones who have had their wiring harnesses replaced by Yamaha; did they cover only the cost of the harness or the labor involved as well?
I've been fighting these issues with my bike for a couple of years but it has recently gotten worse.

That's true.
But haven't been picking up on anyone with the Gen2 having the idle issues of the Ge1 Tens.
Different wiring harness was designed, that was installed into my Tenere.
Since the tech made a comment that it mainly hit the 2012-13 Teneres, i joked may be a tsunami thing?
I wish folks would have gave me phone numbers to give to the tech before he left, as he knows what's going on and reads the forums including this one.
To anyone again CALL and don't stop calling. Find a good service manager that will support you.
I did and it took blood sweat and many tears to get it done.

I may have had God watching over me that day i don't know, but it took a solid hammer to get them to pay attention and again a fantastic service manager that went above and beyond.. Much thank's Robert at Bobby J's!! ;)

Sorry its been a few days, and I do not get emails or any notification when someone replies to this thread, so its hard to remember to keep checking back here.  Anyways, happened again this morning....   ::010::

Did you observe if it does it in T or S mode or regardless.

I was in S mode a couple of times and when I pull in the clutch while cruising to a stop (throttle off), the engine died.  Bike was new then.  The Air screw 1/2 out from fully closed fix this kind of issues. Never had the stall since the screw adjustments.

I am usually always in S mode, but yes it has done it a few times in T.  Good idea to swap back over and leave in T and see if still an issue.

Yes hard to diagnose because its so intermittent, but the shop has seen it happen to them when they had it in august.  I have had it do it to me in all temperature ranges throughout the year, early morning, late afternoon / evening, ect....

2013 - Its in my signature

That is slightly my issue, with the last visit they were hell bent on replacing the ECU as it was on the list of what to do in the service manual.  A Yamaha tech mechanic did come by the shop for a visit and worked with the mechanic in the shop to "fix" my bike when they thought it was the clutch switch.  I guess my next stop is getting bike back to them for them to work on it again, but im just worried they will go straight to the "its the ecu", even though i had the issue when they went ahead and replaced it and when I was riding home it did it again.  So thats when they did the clutch switch and it was fine, they still wanted me to keep the ecu.  I told them no way, put my old one back in and see if the issue comes back, so they did and rode it for a week and no issue so we thought we had it fixed. 

Guess I just need to call them and get it in  ::002::
