I found out today what happened to my week old S4R---The main shaft nut came off ! WTF ?? The duc mechanic said, "Luigi must have had one too many chiantis when he put the bike together ". Hopefuly he was more careful on other parts. By the way, that comment was not intended to be any kind of ethnic slur--I love Italians and things Italian (except Fiats).
