Hey, I'm the guy from the post you linked to. Just an update on my bike: I've since put 600 miles on her and haven't had any problems. The times she died though was in the canyons at a mild elevation (SoCal). I haven't taken her back to the canyons yet, kind of afraid of the same thing happening again, but I guess I should try. The way the engine died didn't seem like it could be from high gear/low rpm/climbing up. The rpms would drop and the rpms barely went up when I twisted the throttle. Slowed her down to the side of the road with the clutch in and in first gear and as soon as I stopped the engine shut off. I dunno what to say...
That sounds very similar to my experience, I was at moderately high RPM in usually 2nd or 3rd gear, and then the RPMs would just start dropping until the bike would surge a few times, then sputter and die.
If I were you, I'd go back to the canyons and try to get it to happen again. Trust me, I know it's not fun to think you'll be stranded (as I thought I was going to be at least twice), but I think it's best to see if you have an ongoing problem, and if so, get it fixed under warranty while you still can.
Plus, if these aren't isolated incidents, and there's some sort of issue with the 09s at altitude, then the more reports Honda gets, the more likely it is they'll have to look into it.
It could be bikes manufactured in a certain date range got a glitched ECU, or sensor, or whatever it is that's doing this.
End of the month is super busy for me, but since I'm losing my riding season I really am going to try to go back out and see if I can replicate the problem or if the ECU swap fixed it.
Unfortunately, if it's altitude + weather/heat, then I won't know until spring as it's already cooled way down in the mountains.
Either way, keep me posted and I'll keep this updated...maybe we can find a cure...
