The problem
TRANSMISSION MAGNETIC DRAIN PLUGS MAY HAVE BEEN BROKEN DURING ASSEMBLY. CONSEQUENCE OF DEFECT: THE BROKEN MAGNET MAY BECOME LODGED BETWEEN THE TRANSMISSION GEARS CAUSING THE TRANSMISSION TO LOCKUP. IF THE MOTORCYCLE IS OPERATING, THE REAR WHEEL WILL LOCK-UP WHICH MAY LEAD TO AN ACCIDENT.
What owners should do
REPLACE THE DRAIN PLUG WITH A SHORTER, NON INTERFERING MAGNETIC DRAIN PLUG.
