This pack you have now is like a dog on a leash and s/he is tugging tight at the clutch lever. What you need to do is remove the oil cap off the clutch cover. Do not tag the threads, nor drop something inside the hole. What you want to do is see what Rook sort of asked on the back end, is spin the back wheel in 1st. So you more or less push the bike with the clutch lever pulled in.
You are looking down in the clutch cover hole and feeding lever to see how and when the bike locks up so you pull the lever back in and see how much throw you have as well? Then, the next thing is to see where that pressure plate is: in proportion to the clutch outer forks or the long tangs of the outer basket? So when the clutch lever is out, that pressure plate to outer basket is what you are looking for. It's a 'stack measurement.'
The pressure plate is going to push the piston back into the slave cylinder, which pushes the rod back in. If say the measurement is short or say less one plate, the pressure plate moves into the outer basket much deeper: losing stack. The rod is pushed back; as normal wear of the plates shrink; the pack moves the pressure plate in.
You now throw the lever and in proportion, the rod calls the throw via the pack being way out there is the perfect stack. So when the throw is at full stack, that rod moves farther out the slave. The rod moves the pressure plate way out there and that makes the plates break away from each other. It makes finding N without dragging of the pressure plate too deep into the clutch outer. There is no lurch or grinding of gear as if you never pulled the clutch in.
Where is the stack? Got a camera to shoot the basket and pressure plate in that hole?
