That bolt in the clutch basket that has left hand threads, did you tighten that to spec in the manual? Not sure if that's related to the dragging clutch plates but seems like it might be.
Regarding the primary chain; the manual says to just get it in the range of allowed tolerances (I don't remember that range off hand). I would definitely lean towards the upper tolerance (looser chain) bc if it's too tight then you can cause nasty issues. But within that range you are good. Also there are two specs; one for warm and one for cold.
