So I notice when I got my TW (a new 2016), I found some issues when upshifting. I would pull the clutch in and shift up, let the clutch out and the bike would still be in the same gear. For a time I though I was not hitting the the shifter hard enough....but then I started paying attention and it only happens from 2nd to 3rd. This doesn't happen all the time, maybe 1:15 times and sometimes it take a few tries to get it into 3rd. What on earth could this be since it is only from 2nd to 3rd? A TW riding friend is going to help me with my first service, but I am wondering if I should consider taking it to dealer if there is something else going on. It is under warranty.
