Hello, I have a 2013 super Tenere, with a brand new battery installed, yesterday I used the bike to go to work, 50 miles ride on the highway and when I got to the city the motorcycle wanted to stop on every traffic light, the only thing it kept the bike on was me continually accelerating. I made it to work and after my shift the bike started fine but after 10 minutes of riding the bike in the city same thing happened again, the bike stopped twice in two different traffic lights, (the bike started back both times) the only way to keep it on was me continually working the throttle, luckily the rest of the traffic lights were all green and I was able to leave the city to get on the highway to get to my town. On the highway I noticed the opposite situation, the bike had a tendency to get stuck on a higher rpm even when I released the throttle. This condition happened several times, every time I slow down I could tell the bike was in higher rpm than normal, this happened for about 50 minutes, every time I release the throttle. when I got to my town I stopped in a gas station put fuel and the bike didn’t start at all, after several tries it started again and I made it home. At home I put the bike on neutral, the bike was on the correct rpm for a little bit and then increased the rpm and then lower it and did that back and forth by itself for 5 minutes. Then I turned off the bike and checked the battery cables, all them were good, battery was 12.9v, the only thing different on the bike is that I installed a quick connect cable on my battery to connect my battery charger to the bike so I don’t know if that could be affecting the bike but I think it might be something related with gas, the throttle or the clutch, any ideas?

Probably one of the two throttle position sensors is not making good contact. First you should check that they are well adjusted. If they are well adjusted, it is likely that they have a false internal contact (due to wear).
Stopping at idle could be related to some other problem (fuel/filter, spark plugs/water)….getting stuck accelerated more than normal, the above would not cause it.

Yes the throttle position sensors would be the first place to start. Happened to me at about 35,000 miles on my 2012.
It seems strange that "just" after changing the battery it started with these problems. I also think I read in a post that a loose battery cable could cause some kind of problem (some kind of weird problem), "but I don't remember if it was related to idling/stopping"...a loose cable but not at the battery terminal, but in the terminal block of the electrical installation. Perhaps when manipulating the cable when changing the battery, the cable loosened or lost some
contact in the upper terminal block

Throttle stop, throttle position sensor or both. Sensor and cable might need adjusting or replacing. It will have nothing todo with your battery.

Being a 2013/Gen1 bike, the first thing I would ask is, has the October 2018 Safety Recall been done on the bike.
Your symptoms are consistent with the problems fixed by this recall.
The APS and TPS each have 4 wires that go to the ECU. The two Blue wires are spliced in with another Blue wire that goes to the ECU. Same thing with the Black/Blue wires. These two splices are buried in the sensors wiring harness so rather than cutting into the harness and repairing the splice, the recall bypasses these connections with a new sub wiring harness.
The title, date, and recall number for the US recall is shown below:
The wiring splice on the Gen1 bikes is known for developing a resistive connection at these splices. Depending how the splice breaks down you may have different symptoms. not returning to idle or no idle at all when coming to a stop. You seem to have both of these issues. I only had the problem of no idle when coming to a stop and it was intermittent.

There is a long thread on the problems people had before the recall finally came out.
No idle and high idle problem | Yamaha Super Tenere Forum
You can call your dealer with your VIN to see if the recall was done.
or better yet check for yourself: Yamaha - Product Recalls --> link
Here is a link to another thread that came out after the recall was issued.
Yamaha Super Tenere Forum | Gen 1 new recall | Page 2, Reply #21
Reply @21 has more links to get recall info on your VIN from the NHTSA.
There are also some links to the NHTSA Recall Report and the Tech Bulletin from Yamaha.

Thank you so much it makes so much sense everything you wrote, the bike is 2013 but it is practically new, I bought this bike in 2016 when I found it In Yamaha dealer sitting on a display unit for 3 years, I made an offer to the dealer and they put oil a new battery and I rode the bike back home, the bike now has only 1800 miles, from my 3 bikes this one is the one I ride less so everything looks new, I got surprised last night because it is the first time it happened and to be honest it was scary, I felt very insecure when I got to a traffic light because I didn’t know if the bike was going to stop again on the middle of the road. I will get the vin and call the dealer hopefully this is something they can repair for free if they don’t fit it for free for any reasons, is that hard to replace or fix the wires myself?

Yamaha requires this to be done by a dealer unless you can find a way around that.
There should be no charge by the dealer but I would confirm that. If they want to charge, I think I would check elsewhere.
The new harness will have 2 new connectors that plug into the APS and the TPS on one end. The other end will have 6 loose wires with terminal pins crimped on them.
The installation:
The APS and TPS connectors will be cut off the old harness and the wires folded back and taped to the old harness. The connectors on the new sub harness will be plugged into the APS and TPS.
On the other end, 6 wires from the old harness will be removed from an ECU connector and 6 pins on the new harness will be inserted in the ECU connector. The 6 unused wires on the old harness will have the pins cut off and wires folded back and taped to the old harness.
This should be a simple procedure for a competent technician. I would ask the service department how many of these they have done. Depending on the answer you may consider asking other dealers the same thing.
I believe they are also required to have you bring in the bike and they keep it until they get the part and install it. Some may not do this.
Check the links I gave you to learn more about the recall.
I would also use the links to check for yourself if the recall was done.
I hope this doesn't sound like I don't trust some of the dealers.
Good luck and let us know what's going on when you know more about this.

Thanks again, I called the dealer and base on the vin of my bike they will replace that part but he said he does not believe this will fix the problem but he also said he was not very familiar with this recall so I asked nicely if he can learn a little more about what this recall fixes and call me back and he said he will do that. I also explain that I have to ride the bike for 60 miles to get to the closest Yamaha dealer and in this condition if the recall does not fix this problem I will need to see a Kawasaki mechanic (that is my only option in my town) then one the problem is fix I can bring the bike for the recall. He understood and he was going to search more. I trust more what you are saying that what he thinks so I challenged him to get more information. I will read more about this so I can learn more thanks again for explaining this with so much details and patienceYamaha requires this to be done by a dealer unless you can find a way around that.

The Yamaha dealer called and confirmed that what my bike is doing is part of the recall, they said the have done the recall on many bikes but mine will be the first one showing the signs the other one didn’t. I’m planning to take the bike to the dealership on Friday and I will keep you guys updated! Thanks again

If the recall doesn't fix it, I suspect an air leak somewhere, maybe a perished cap on the vac port, as it shows itself when hot.
BTW, it's always best to start the fault find by checking for stored codes - available via the dash on a 2013. Obvs the dealer will interrogate the system when dealing wit the outstanding recall.

Did this problem pop up immediately after the battery install?
