I only have about 500 miles on my bike but over 300 of those miles have been balls out on the track - which included one lowside that shaved the shift lever down nicely (less weight now I guess

). I have not had any tranny problems, no false neutrals, nothing. Solid consistent shifting. Although I will say that to find neutral you have to go down to first and back up to neutral. Getting to neutral from second is seemingly not possbile.
As to the problem here, all my shifting is at 10K+ rpm except for blips on downshifts and when short shifting but even then never below 8k+ rpm and that would be going downhill. Maybe some people are simply shifting the bike incorrectly on both up and downshifts - user error. Not enough synchronization of the gears.
I suggest shift up at 10k+ rpm only and blip the throttle on downshift but never shift (up or down) below 8k rpm and see if you don't get better response from the clutch.
What a wicked bike. 100+ MPH in 2nd gear at 14k rpm you have to love that [

]. I've done both T-Hill and Infineon and no need for more than fourth gear![:0]
