1993 KAWASAKI EX500 Engine And Engine Cooling Problems

THE FLYWHEEL (ROTOR/GENERATOR) OF A 1993 KAWASAKI EX500, , MANUFACTURED IN SUCH A WAY THAT THE MAGNETS ON THE ROTOR ITSELF WILL BREAK APART. A LICENSED MECHANIC HAS TOLD ME THAT IT COULD POSE A POSSIBLE SAFETY HAZARD CONCERNING THAT IF PART OF THE MAGNET WHERE TO BECOME JAMMED IT COULD SEIZE THE MOTOR OF THE MOTORCYCLE UP. THIS HAPPENED TO ME, I WAS ONLY PARKED IN MY DRIVEWAY, BUT IMAGINE DRIVING DOWN THE HIGHWAY AT HIGHWAY SPEEDS AND ALL THE SUDDEN YOUR MOTORCYCLE ENGINE SEIZES UP. THIS POSES A SERIES SAFETY RISK NOT ONLY TO A MOTORCYCLE RIDER, BUT ALSO PEDESTRIANS OR OTHER MOTORIZED PEOPLE. THIS COULD RESULT IN DEATH! IN 1993 THE ROTOR WAS MANUFACTURED IN A WAY THAT ALLOWS THE MAGNETS TO COME APART DUE TO POOR/THOUGHTLESS DESIGN FLAWS. NOW I AM TOLD THAT A 1994 ? PRESENT, ROTOR HAS AN INNER LINER THAT HOLDS THE MAGNETS...
