All I can say is, if the bike is new, take it back to the dealer and get it adjusted properly.
My experience is that I have plenty of adjustment available on my clutch cable, with no issues. With your new bike, your experience should be similar.
With the spec'ed amount of slack gap at the lever, and it drags (not fully disengaged) when shifting, there's a problem somewhere.
Adjusted the way you say - tightened up until there's no "drag", but no free play - there is a risk that the clutch is not fully engaged, and that will kill your clutch pretty quick, as it may be slipping under load, perhaps imperceptibly for now... As I'm sure you understand.
Just my take on it.
