I have been looking for a V11 to buy and have found a few close to me. One seems to have had the service done, Piaggio is still digging on that one for better confirmation and one does not have any recorded info on the service, just warranty registration in 2002.
Is the tranny repair something that still can be done? I would figure parts might be hard to come by. I could pull the trigger on a low milage greenie, but wont take the risk without the repair.
I found the recall campaign Service Announcement No. 17-2003, dated October 22, 03, on Gregory Bender's wonderful site:
