I'm sorry but the thread title made me laugh (I know it's not a funny topic). It's just stated as if it's a normal occurrence and reminds me of Dumb and Dumber where LLoyd says "Fell of the jetway again"

Feel bad for the OP, I would've lost my mind

I have some information to share with my fellow Super Tenure owners/riders on here.

On Friday evening, I heard from Masaki Kobashigawa at Yamaha headquarters, via email. My dealer submitted a "service difficulty report" (?) to Yamaha, disclosing what happened, and the events that led up to it, to the best of our knowledge.

First off, we have Yamaha's attention regarding the hard start issue. Secondly, they're wanting to use my motorcycle for research, and when insurance is done with it, they'd like to buy it from them, and ship it to their facility for research and study. They want to know exactly where the fire started, and what exactly caused it. In exchange for my "trouble," and letting them use my bike for research, as well as being available to their engineers for any questions that they may have, they're offering to give me a 2016 Super Tenere. However, the 2016 will not roll off the production line for about one more month, so there is a wait.

Masaki also told me that under no circumstance, should the start be energized for more than 10 seconds at a time. The starter is absolutely not designed for continuous operation for over a minute. I'd like to ask those on here to please stop dispensing the advice of "cranking until it starts" because it is bad advice, and costed me my bike.

KWC sorry this has happened to you and thankful your getting a new replacement. I guess the hard start may finally have Mommas attention.

Hmm, wonder if the battery had been replaced recently...

The battery was the same one that came with the bike. Never been replaced.

I feel like we're pointing fingers to other things (regulator, battery, etc) but missing the fact -- My bike caught on fire due to excessive cranking of the starter - nothing else

Yamaha is aware of the hard start issue, and is working on a fix. Yamaha says it is caused by a mixture rich condition caused by a bug in the ECU. In early 2016, Yamaha is supposedly coming out with an ECU software fix that will remedy the issue. In the meantime, these are the instructions that supposedly will get a bike that fails to start, started:

(1) Identify hard start and stop cranking
(2) Turn kill switch to "kill" position
(3) Turn off key
(4) Wait 5 seconds
(5) Turn on key
(6) Turn kill switch to "run" and IMMEDIATELY start cranking
(7) Bike starts

The supposed ECU software fix that is coming makes me wonder what will happen to all of those with flashed bikes? Is anyone aware whether the engine software and throttle mapping are stored separately on the ECU? If not, I assume those with flashed bikes will lose their throttle maps if they apply this manufacturer ECU software modification. Is anyone able to confirm?

We were after the effect, not the cause. We know that cranking the starter was the cause, what did it effect. Did the battery burst? Did the cables have a arc at the battery or starter bringing about an open flame. Did the entire length of cable insulation ignite. And I too don't see how a regulator would figure into a start-up scenario, melt down while running, absolutely, not while cranking. It's all hypothesis. Short of having Checkswrecks fly out there and take a look, it's all just a puzzle for the mind.
My condolences, I am glad it didn't get worse.

They're going to give you a 2016? Awesome. Maybe mine could catch fire too?

In exchange for giving them the charred motorcycle AND signing an agreement to not sue them over this event.

Good luck with the suing thing...... Nowhere do they state that you must hang on the starter for a minute plus until it starts. Just be real happy that you are safe and that Yamaha is stepping up.

I've seen pictures of a melted connector that is connected to the starter relay, blackened and melted to some degree on a S10 in Singapore and was posted in a Closed FaceBook page. If I find the pics, I will post it.

I don' know if this could have triggered a fire, but I do know that a connector that is designed to take the electrical load should have no issues unless an internal arching occurs. Poor connectivity between connectors can cause the arcing and this can cause electrical fire. This was the Headlamp wire harness recall Yamaha initiated last year.

With a wet combustion chamber, I don't see how it can. It's nice that they've laid out a procedure, but it happens so seldom, I don't know that it can have actually been tested very often. And it's really really nice that they've pin pointed a glitch in the software, I'll be in line for the reflash, but wouldn't said glitch rear it's ugly head more often? For me it's three hard starts and two stalls in four years, 33 days and 50k. Doesn't seem like programming. I'll be watching the Forum for news, that's for sure.

Pictures of melted connector on the wire harness to the Starter Relay.



It was also caused by excessive starting after the battery went flat and using the an external battery source as a remedy. I guess it went into a hard start situation.

I am not as mechanically oriented as many of you. With that said, if it's not programming, what is it? It seems that the consensus is that the hard start is caused by a flooded motor. So, I must ask, what causes the motor to be flooded, if it's not the programming?

My only problem with it being the programming is that the ecm is actually pretty stupid. It does what it's told, the same way, every time. If it was programming it would/should cause the problem a whole lot more often. Maybe it has the potential to do it every time, the scenario just has to be perfect for it to happen. Key cycled, very short run time, whatever it is, the injectors are dropping some extra fuel when they shouldn't. Maybe at that one perfect point the ecm is putting voltage to the injectors when it shouldn't. Dunno. As with most things diagnostic, it has to happen right in front of you while you're watching the exact right spot for anything to be done about it. Or have a history with a particular failure; if A happens, B could be the cause. It's a damn PIA, but it's been interesting to say the least.

I'd say it was the smoke and fire that got Yamaha's attention.... not so much the hard start. They know about hard starting for several years.
Had the op been injured in the mishap Yamaha would have an ugly mess to deal with.
Remember the mess they got into with the Rhino? They don't want to go there again.....

true but continued operation will heat the weak parts in the route to the starter which are any connectors and the starter relay contacts, I guess at some point either the cable or relay insulation or some other combustible material its mounted against will catch fire, its worth remembering that the feed to the starter on most cars and bikes has no fuse, so it will turn over and over until you either flatten the battery or give yourself a serious issue

Wow! Sorry to hear about your bike and glad you are ok.

As in other industries it takes a major event to get enough attention to make a change. Fortunately no one was hurt or killed. Yamaha has now recognized there is a problem and is dealing with it. I think that speaks well for Yamaha. A friend had a very dangerous issue with his Triumph Explorer and it wasn't until the bike died in front of an oncoming truck that they lemon lawed the bike and gave him a new one. They did nothing about the problem and made him sign papers that he would never discuss the matter with anyone. Guess they forgot to have me sign anything! The problem still exists with other Explorers and is a danger to anyone riding them. That is the other side of the coin and speaks poorly of Triumph.

Somewhere on this forum I wrote a big ole explanation of this. see if you can find it because all the answers are there.
