Looking closer at your picture, the release plate is installed backwards. You should not be able to see the entire face of the release bearing. The release bearing shoulders on a lip, which is not visible, which means the release plate is installed backwards...
We have a winner.
Took everything apart and reassembled it; it did the same thing. Opened the manual sent to me by a member here and looked at the picture. Slapped myself on the forehead, re-bled the clutch, reinstalled everything and went for a ride.
I have no idea how I got the release plate backwards, as I didn't recall separating it from the release bearing last night. What I get for plowing ahead with a job when I know I'm too tired to do it.
Thanks so much for everyone's help. I'm going to sit in the corner for a bit with a dunce cap on.
