Yamaha Motor Corporation, USA
The problem
THE SHIFT CAM STOPPER BOLT LOCK TAB ON THE INVOLVED VEHICLES MAY NOT PREVENT THE STOPPER BOLT FROM LOOSENING. THIS COULD ALLOW THE SHIFT DRUM TO MOVE LATERALLY.
What owners should do
THE DEALER WILL INSTALL AN IMPROVED LOCK TAB THAT WILL STOP THE STOPPER BOLT FROM LOOSENING, WITHOUT CHARGE TO OWNER.
