I will google "wet clutch" and "Oil Bath clutch".......

No wear in the linkage.......I over adjusted it to the point where it would move the machine with the clutch out but it still dragged real bad when trying to shift it. I had it so I could not push the pedal to the floor it would stop because the pressure plate was out of travel.

There are NO syncro's in the trans.

I'm thinking the wavy-ness has parts of the disc touching between the flywheel and PP and that is causing the drag...
And I'm thinking BBforks is right.....the disc should be perfectly FLAT with no wobble and no spots that touch between the gap when the clutch is disengaged....
