Hopefully you were not allowing the shift lever to completely return to the middle (common occurrence); otherwise it's not normal. Try removing your boot from the shift lever completely, and see if that happens again.
My problem, still happening at 12K miles, is the shift from 1 to 2nd, but when HOT. I still have to be VERY deliberate with the shift, but sometimes it just refuses to click 2nd, as hard as I try. I don't like that at all, but it goes away. That happens when the engine has been cycling the fans due to traffic. When cold, it shifts perfectly. And never a problem donwshifting, or upshifting other than 1-2. The problem obviously is thermal expansion, and since I ride just for fun, I might have the equivalent of 2K miles on the bike, since I might travel over 100 miles for every 1-2 shift I make. Who knows. ANy guesses? WHAT'S CAUSING NOT TO HIT 2ND FROM THE 1-2 SHIFT??? Just curious.
Oh, and this thing is practically impossible to shift smoothly, even after 12K miles. I shift my other (Japanese) bikes like a pro since day 1, and most of them with hydraulic clutches as well. Could it be the stupid dry clutch? Maybe, but it's frustrating. Take care.
