Good luck UK. Hope you get it all sorted out. I had the same first days false neutrals on my 2015 as TDH and some of the same problems, or so it sounds, as you do. Only complaint about the bike. After a few missed shifts in the upper rev range I've really lost my confidence in this tranny. Before my quickshifter it happened a couple times, I think 3rd-4th, maybe it was 4th-5th. Scared the crap out of me every time. Thought it was me so went to a quickshifter. Woolich and race tools, I think. Works flawless 99% of the time but still in the upper gear range at WOT it will miss a shift. Very rarely but it has still been a problem. Hope you keep us up to date on how you get it sorted.
