Alright, I’ve now ridden with these carbs about 2500km. There’s only a slight drop if I pull even a little too fast. Verified temporary lean condition with colortune. But if I pull nice and steady, it’s just fine. Seems even a touch faster at top end. Not as difficult to hold 60-65mph. A little annoying, but not too bad. Plugs look perfect. 40 pilot 140 main.
