I wonder if anyone has correlated this problem by model year? Just coming up on 8K miles on my '15 ES and so far so good in spite of doing a few of those short on/off starts that seem to precipitate the problem.

Not had a hard start and just had my ECU remapped ..... so either the ECU update doesn't touch my lovely throttle settings or i will not not touch the ECU update ...

I just stumbled upon this topic. It has been over a year since the original post. What was the outcome? Did the Yamaha ECU remap ever happen? I have a 2012 and experienced hard starts intermittently for the last year. I have had some other fuel mapping issues that cause the bike to surge, die at intersections, and fail to restart. The problems also seem to lie with damp weather too. I'd take to a shop, but the problem doesn't hang around long enough for the shop to find.

My 2016 Super Tenere, compliments of Yamaha has arrived here in Hawaii!! I will be picking it up on Thursday, once it is assembled.

This week, I did get a chance to speak to the powerplant engineer at Yamaha, who had a few more questions for me regarding my bike fire. He told me that my 2016 has the ECU software fix in it, so the hard start SHOULD be solved. I certainly hope so.

I was also told that the ECU hard start fix will come to USA registered, pre-2016 motorcycles in the form of a voluntary recall from Yamaha. It will be scheduled with your dealer, and Yamaha will send a new ECU for those motorcycles, and the dealer will send the previously installed ECU to Yamaha as a core. It is expected to be issued in early 2016.

I've had a hard start a few times, pretty much always when I started the bike and then shut it off before it warmed up. Each time WOT start solved it, so not an issue imo, and certainly not worth losing my flashed ECU over.

Wondering the same thing. Not having yet experienced a hard start episode, I would be reluctant to swap ECMs unless I know what the other changes are. Road tests of the 2016 models should tell us more about any fueling behavior changes.

California seems to have a policy of not allowing registration renewal of vehicles if there are outstanding emissions recalls.

Makes me wonder if this will be considered an emissions recall, and therefore cause California Super Tenere's to be forced to do the update?

No, this will not cause any issues in California. Heck, my '09 VW TDI which has major emission issue's, was just re-registered without any problems in California. Although no formal recall has been done.

With the VW "dieselgate", there has been several articles on California emission/recall laws. California, even with the laws on the books, has never enforced them as far as recall's if the vehicle has been previously registered in California. Heck that would keeping money away from the state. Can't have that...

Darn, just posted my hard start issue in another thread. In the midst of trying to get mine started. I love the bike with the ECU flash. Not going to spend the money to do it again. I'll get my fix from Yamaha and sell it.

My 2014 Super Tenere ES with 22k miles is having a hard time starting damn near every attempt at cold start now. Nearly every time I've been off of it for long enough for the engine to cool - it won't start without several attempts. I'm about to do my valve clearance check/adjustments and I'm hoping that helps. Although, I'm keeping fingers crossed that Yamaha helps to put this formerly to bed ASAP. This is incredibly frustrating and the only thing about the bike that I don't love.

How old are the spark plugs?

What you describe is not the classic "hard start" most discussed on the forum. Get your battery load tested. With only 22k miles, nothing should really be wrong with the bike. The valve check isn't due until 26k miles. I would suggest you sort out the starting issues before you dive into bigger things, you may only confuse the diagnostic process.

Not knowing you, or your normal starting routine, or the ambient temps when your bike has difficulty, it's hard to offer more constructive advice. I don't want to assume you're doing everything right, but certainly don't want to assume you're doing things wrong either.

What's your normal start procedure? From Key on, step by step what do you do? It might point in a direction to check on something.

I tend to agree with the combined response of Bertrand and EricV. To start with, make sure the battery is good and make sure the plugs are good. My 2013 ST has the original plugs (22,000 km or 14,000 miles). I already have new plugs on hand but am delaying changing them. With a weak battery (not charged for more than a week) and old plugs I risk a hard start, as in fact happened a short while ago. If I don't use the bike for a week I always put the battery on charge for a few hours before attempting to start. This gives the battery sufficient juice to give an adequate spark on an old plug. Weak battery = weak spark. Old plugs = weak spark. Weak battery + old plug = no spark. That's my experience.

As some may recall, due to the "hard start" problem, my Super Tenere caught on fire. Yamaha was nice enough to give me a 2016 as a replacement. They also told me at the time that a hard start fix was in the works. Yesterday I received an email from Yamaha in Japan, from the engineer who diagnosed my bike that caught on fire. He informed me that Yamaha USA has agreed to do a "mandatory recall" on the Super Tenere, which will be an ECU software fix which will fix the hard start.

While I feel for those who have ECU flashes (I do believe they'll be erased) given the severity of the problem, I think this is wonderful. How they plan to make it mandatory, and whether it will be distributed to other countries in time, I do not know.

So, did this software reflash that the original poster said was coming in 2016 ever materialize?

Did anyone have success with the starting procedure the OP wrote?

No to the first question.


Yes to the second has been reported. For more info, here is the dedicated hard start thread. It's a sticky in the Power & Exhaust sub-forum.
