loose flywheel nut
I have a fioroni turbo sliding clutch and the nut loosened up last season;I tightened it and it was fine for the last race. I just took it apart to put on my new P5 and i see the flared inside piece(name?) goes flush into the flywheel. It did tighten up BUT think I would be better( safer) getting a new flywheel?
BTW I had a heck of a time getting it off the old engine. It was on tight. Still I see damage where it was spinning
