Really interested in this thread as I'm a potential AT buyer. Any news from Honda or anyone on it? It does appear to be an issue since so many have reported shifting problems.
Honda is shaking its heads most likely.......as they suspect like a few others have posted and I believe, it's an issue with the rider. How one shifts, how soft a pressure is applied, how many miles the bike has (most of these issues here the bikes are less then 1000 miles if not less then 2000 miles), and most have Pivot Pegz (which in themselves causes people to think they're shifting when in fact they haven't applied enough pressure).
I'm sure to get hate mail......but I too had maybe 3-4 false shifts, the popping out of gear or into another gear (as some might call it), all while the bike had less then 2000 miles. I realized after about the 3-4 false shift that I was the issue, not the bike! I didn't apply enough step (force) in the shifting or the correct coordination with the clutch. I have over 9000 miles and have had ZERO issues since. I've posted it before and I'll post it again. Try taking your pivot Pegz off, use some force, coordinate your shifts better and more importantly, go ride the **** thing! An oil change might help a little but for me, I got rid of the Pivot Pegz and started to pay attention how I shifted and now I don't even think about any of these "problems", I couldn't be happier with the bike.
I'd almost put a wager Honda comes back in almost every one of these cases doing little to nothing saying it's an owner issue, no discrepancies found. I write this without spite, and I don't mean to start a flame throwing thread but go ride, stop typing. Cheers.
