OK...this is turning out to be one of the most frustrating weekends I've had in a long time and I'm feeling like an idiot. My Evo slave cylinder started to seep this week, so I figured it was time to pull it apart and rebuild it. I emailed Evoluzione and they mailed out some replacement seals and a new piston right away with no questions asked. Very cool.
I go to install the replacement piston in the cylinder and it barely fits, and won't slide at all down the length of the cylinder. I'm bummed and figure I messed up somehow, so I reassemble with the old piston but new seals and bearing. The unit seems to work smoothly so I install it and start bleeding the clutch system...here is my procedure:
lid is resting on master cylinder but not sealed. I pump the lever for about a minute, then crack the master banjo bolt, repeating until I see no bubbles. I pump the lever some more and crack the slave banjo bolt, repeating until I see no bubbles. Action at the lever is fairly light, and the clutch isn't working. I then remove the slave cylinder and slowly compress the piston with my thumb, while watching the master cylinder for bubbles. Fluid seems bubble free, so i reinstall the cylinder, pump the lever and crack the master banjo...no bubbles. Clutch still won't engage when the bike is in gear. I removed the clutch cover and the plates move outward a couple milimeters, but that's it. There don't appear to be any leaks anywhere either. I've been doing this for HOURS.

Am I missing something? This was the same procedure I used when I installed the cylinder 4 years ago and everything worked perfectly. I don't know anything about the clutch, so would appreciate any input as to what I should look for in case there is another problem in addition to my slave cylinder. The Duc has been so much fun to own, but I'm getting pretty discouraged.
