Bought my Hyper 821 just last week, and having the first gen already in the stable and modded out, I couldn't live with the grabby clutch so added the 4 pieces from the eBay anti shudder kit this weekend. I ran into a big problem not discussed in detail on this thread where the spacer between the clutch basket and clutch pack was binding and causing my clutch pack to stick out an extra 1/8-1/4". After I sealed the clutch cover and installed everything back, I noticed that my clutch lever wouldn't disengage the clutch. I had to remove my cover again and it took me a while to figure out why my 32m nut was not sitting at least flush with its bolt. I finally shoved the clutch pack in right after messing around with it and that spacer was the issue. Then when I started the bike after testing that the clutch was engaging - it was super hard to shift, like the clutch plates were jammed or something, and I couldn't move the lever to neutral unless the motor was turned off. Turns out the cable as discussed in this thread needed to be adjusted and that solved the hard shifting and neutral problems. 821 runs like a champ now (fingers crossed) and shifts easier than my old Honda sportbikes. WTF was Ducati thinking and I can't believe the previous owner rode it like this for 11k miles. It nearly threw me off and I almost dumped it on my test ride like week. (I've been riding for 20 years and this is my 4th Duck) Now my first gen has some pretty stiff competition. I want to thank the OP and all contributors to solving this issue, now lets see what a new exhaust will do.
*Also, want to add that using clamps to compress the clutch pack worked a lot better for than trying to wrench a 3mm nut.
I upgraded mine just in time to sell it. Such a shame, but those were a great 3-4 rides!
