OK, let's try and unconfuse you.
Clutch failure can have many causes. Cheapest fix is to readjust. Start with the cable, then the throw out rod.
The clutch pack screws have to be tightened all the way for the clutch to operate.
If the throw out rod is too long it'll stick out of the pack more than 13mm. When you tighten the cover, it pushes the pack in.
And will be too short at 12mm, I regrind them to 12.5mm sticking out of the pack.
The more it sticks out, the better mechanical advantage you'll have too.
When you pull the clutch lever, the lever is pulled up and the pack is pushed in.
The 1st time I re-assembled my clutch it was jammed and wouldn't operate. Perhaps the washers weren't properly aligned. All I did was take it off the bike and shift the plates side to side, then reinstalled it.
BTW, while you're there, measure the cam chain adjuster, the amount that the plunger sticks out shouldn't be more than 19mm. More than that and it starts damaging the housing the plunger is in.
