Well, might be a one-off manufacturing fault of this particular engine or caused by the fact the CUP bike is used for the racing track, but last week there started to sound awful sound from beneath the stator cover after one racing session and when opening the side of the engine up to inspect the results were as seen as they are.
The cause of the failure was one of the 6 rivets breaking loose from the flywheel what did manage to destroy the alternator as a result.
