I think (and others can confirm) that all Ducati did was loosen up the clearance tolerances on the valve shims. Thus, it can go longer before you need to check it or re-shim it (theoretically). This is largely moot as experience has shown that valve shim clearances hit a stable plateau soon after 12k miles.

If you aren't afraid to spin a wrench, I wouldn't worry about your dealer. The Desmo engine, while a little intimidating at first, is rather easy to work on. Get the books, search the web, etc., and you will find more information than you could ever hope for to repair your bike. There are great on-line parts sources, as well (California Cycleworks is one). Hell, motogpfan will sell you motor oil.

Good luck. Buy the 800. Hope this helped.
