Josh is correct, but don't sell the bike.
Nothing like passing misery to another unsuspecting owner and knowing it was a lemon.

With that, it's the same line of BS i got from Yamaha..
I would try another shop that has been around for some years with a good reputation of good service...
The service manager is being lazy, with that in mind i wouldn't let him change a tire...
USA Yamaha gave me the same line of Shit as well, they know what's going on as i was told they have replaced harnesses and that the issue as i have said many times with the 2012 and 2013 models.
Relocating the Stator cable doesn't work you can check the battery till the cows come home, i replaced mine and that didn't work.
You can record it while it's happening but as with most cases it will happen when you can't do this..

This SOB Gremlin follows Murphy's Law, when it happens it only happens when you are alone and not at the garage.
Like the old loony tunes cartoon, the demolition guy that finds the frog that sings but he can't get it to sing in front of the music promoter...:D

Do a little test, take the battery side cover off start the bike while it's idling lightly push a tug at the pile of spaghetti harness wires at the top and see if you can get a reaction form doing this. Don't go heavy handed just wiggle stuff and push and pull the wires.
I was able to get a reaction on one wire don't remember what one it was..
The tech that did mine only was able to get it to stall.


Since he had the harness with him he just replaced it and it's been running fine ever since.
Report it to the highway safety web site a few of us have.
You need not stop calling, warranty or not it's dangerous, not normal and not a comfortable feeling.
Like if i just happen to be riding and it jumps RPM's and i slam into the rear end of a car, stall turning at a turn light and get rear ended by a car behind me.
Off road and this all happens stalls in the middle of nowhere.. Just think of the law suit that could come of this...
I will back you on that, it's not right for them to blow you off on a serious matter such as this..
You have to be creative on all the safety concerns about this issue.
Tell him you reported it to the Highway safety, tell him your concerns are serious.
And to let you know they are reading this and are taking a head count..
So keep being persistent and don't stop..
But do find an honest serious Yamaha service manager...
Would be nice if us fortunate ones could give the name and phone number of the Yamaha service manager that helped them out.
YOu can call them and ask for some advice to point you in the right direction in your state or surrounding states.

This was my five star angle service manager at Bobby J's Yamaha his name is Robert the phone number is: (505) 884-3013
Tell him the year the symptoms and that you can't find any shop manager that will take you seriously and with Yamaha USA customer service.
And that you read from a guy in New Mexico on this forum that had this problem completely fixed in his shop and ask what should you do..
If others can add to this list we may have something to place a bet on, it's a long shot and they may be able to get some response
Apparently he had enough clout to get them to cover me off warranty and money in my pocket as well...
I was happy just with the fix and the fact that there honest people still give a shit working in the business..
It's only a long distance call why not?

Thanks guys for all the input! Will see if I can replicate it in the garage and video it. Will also hit up Robert. A bit from Michigan but maybe he can give me some points remotely.

So I am st about 10 starts and 120 miles on bike since new wiring harness and so far no issues like before. However now it is running rough at 3000-3500 rpm, lots of sputtering popping out exhaust. Wondering if fuel is related, old and been sitting so long. Burning through this tank to then refill with fresh fuel before calling shop.

Well I just got back from a 17,000 mile trip from San Diego to Alaska, up to the Arctic Ocean, to the east coast and back home again. I did the required 26k valve check early (20k) miles and ever since then I haven't had the idle/revving issue. Perhaps while I moved the harness, or disconnected and reconnected the plugs I solved the problem? Interesting......

looks like someone has documented video of it happening to him, and its right along with what I was experiencing, besides the bucking issue near end of video


I also got an email from NHTSA askign questions about my issues

Wow. That's pretty damning. Interesting to see if that has been sent to NHTSA. (My 2013 has been really good - it died once about a block from the house and wouldn't start, and i've had one other hard start in 25K miles.)

He's also got a Part 2 to expand on his issue:

Again, if you have these issues go to NHTSA at SAFERCAR.COM and file a complaint. These are what the manufacturers REALLY pay attention to, because they are what NHTSA uses to develop recalls. I believe that you can post links to files like these videos IF IF IF yours is really identical.

I have several videos of me almost hitting cars at intersections when my motorcycle surged forward. I will see about posting on YouTube since they are to large for this site. I have been a loyal Yamaha fan for 50 years and I cannot believe this has not been addressed. This is a death waiting to happen or how many deaths have already happened. Yamaha where are you?????? Is this something that takes many deaths to get your attention? I have filed a complaint at the NTHSA but never heard anything. I know there are three things regarding a lawsuit. What did you know ? When did you know about it? What did you do correct it? I believe you have known what the problem was. I believe you have known for at least two years. I also believe people in people in management have known about it (because they have replace wiring harnesses at no charge with no warranty). I also believe that that it is trying to be hidden so they dont have submit a recall. There has been no concerted effort to address this. Yamaha??

Every problem a few encounter is not reason for a recall. Great that Yamaha has helped a couple guys that were out of warranty. Have to give them credit there. I wonder when motorcycles were even first considered for recalls? Back in the 70s and 80s even if the wheels fell off there was no recall. No one ever heard of a recall until at least the 90s on a motorcycle.

Re: Idle speed problem min 800 max 3500

Long delay in getting an answer on this as I went on holiday while the shop had my bike.

Turns out the linkage on the side of the throttle bodies was seized. I haven't picked up the bike yet due to work so haven't been able to get the mechanic to point out exactly where the problem was, but apparently Yamaha have been asking questions as they haven't seen this before. They wanted to know if I lived by the coast, was the bike used much and do I do short or long mileage trips.

I live at least a 100m from the sea. The bike has done approx 14000m this year. Riding is work/commuting only and shared with an FJR, with most of my journeys 100m plus.

The bike was left sitting for 3-4 weeks before this occurred which can't have helped. I was moving house and waiting for a new set of dunlop rs2's and it hadn't been washed, but even if it had I don't tend to be that detailed when washing it. As I use my bikes all year round this isn't a good sign, if it's just a case of more careful washing I can cope with that, but I had enough problems with the FJR that I was told needed a new wiring harness at 3yr old and all the earthing issues. If the S10 is going to need constant attention with panels off, deep cleans, etc. then perhaps I need to look elsewhere. Can't imagine many modern bikes are going to be that different with all year round riding requiring high maintenance.

I had a similar problem with my 2011 S10, poor idling and misfiring at speed, it took me and the dealer months to find the fault.

The fault was due to poor connector contact plating on the wiring ( four wires, some screened) from the TPS to ECU, the same real problem as the S10 recall on the headlight cable assembly.
There was a recall on the R1 number RM/2013/031 for a similar problem.
On this recall they supplied a new cable from the TPS to ECU to cure the problem, it will fit the S10 and has the same wiring colour coding.
I have written a letter of complaint to Yamaha, as I regard it as a safety issue, as on a closed throttle the res would not go below 2,000 RPM.

I talked to a guy last week that has a 2012 and he was out east riding the East discovery route when his bike started idling at 3,000 when he put it in gear and he had to ride slower or faster just shifting up or down no need to ever give it throttle.
Then it was getting very hard to start.
He said that he made it to Romney Cycle and they called Yamaha and started to explain the problem and Yamaha said replace the harness.
They paid for it but he had to overnight it at his cost of $140.
He said it runs great now.

Yes, that was an option I had, but he bike was out of warranty and the the main cable harness is £1,100, fitting it £400, so not really an option, the R1 recall cable is about £50 with fitting about £100.
