I don't want to toss in a whole new variable into this, uh... *discussion*...
Nor do I want to hi-jack the thread into heading unnecessary directions, but...
First off, I tend to agree with EricV. The problem does seem to be limited, most often, to some rather specific parameters. I even experienced the "hard start" issue a couple of times early in my Super Tenere ownership, but fortunately each of those two times I got the bike started without exhausting the battery.
That said, there is something else that points toward the "problem" (and I use that word only because some see it as one) being a software issue. You see, ever since I had my ECU re-flashed with the ECUnleashed programming I have *NEVER* experienced the issue. In fact, it has always seemed to start up much easier, with fewer turns of the crank, since the ECUnleashed re-flash.
Now, does that say that the ECUnleashed re-flash *cures* the problem, or that something in their re-flash somehow corrects an issue the stock OEM Yamaha software has? Or does it just say I had gotten so used to avoiding the problem that it hasn't reoccurred?
Honestly, I can't readily answer those questions. All I know is that my bike starts easily all the time, period.
One thing to note here... The ECUnleashed does completely away with the "closed-loop" operation of the Yamaha ECU, and operates entirely "open-loop". In fact, you can completely remove the O2-Lambda sensors without a problem. Who knows, but perhaps this has something to do with why the bike starts so readily with the ECUnleashed re-flash.
Just FYI...

p.s. I should also say I am a *HUGE* fan of the ECUnleashed re-flash, and of the shop who did it for me, AF-1 Racing in New Braunfels, TX. It simply makes the bike run better throughout the rev range, eliminates any and all stumbles or drivability hiccups, gives smoother throttle response both getting on and off the throttle, and has a myriad of other positive improvements over stock.
