2005 YAMAHA MAJESTY 400CC SCOOTER STALLING IN TRAFFIC. ENGINE WAS WARM, COMING TO A STOP. ENGINE STALLED AROUND 5-10MPH. THIS IS THE 5TH TIME SINCE NEW. CONDITION VERY SERIOUS, AS I WAS ALMOST RUN OVER BY TRAFFIC DUE TO SUDDEN LOSS OF POWER/DRIVE. THIS IS A LAWSUIT FOR SURE. ON A VERY SMALL YAMAHA SCOOTER FORUM, THERE ARE ALREADY 38 OTHER RIDERS WITH THIS EXACT SAME SCOOTER THAT HAS STALLED AT LEAST ONCE. HTTP://MAJESTYUSA.COM/FORUMS/VIEWTOPIC.PHP?T=486&POSTDAYS=0&POSTORDER=ASC&START=0. THIS IS A VERY SERIOUS COMPLAINT I'M FILING. I ALMOST GOT SERIOUSLY INJURED OR LOST MY LIFE YESTERDAY DUE TO THIS ISSUE. SINCERELY, THOMAS *TR
YAMAHA IS RECALLING 9,600 MY 2006-2007 CP250 AND MY 2005-2007 YP400 MOTORCYCLES. THE ENGINE COULD STALL AND BE DIFFICULT TO RESTART BECAUSE THE WIRE TERMINALS IN THE FUEL PUMP WIRE COUPLER HAVE CORRODED. WATER CAN ENTER FROM THE MAIN WIRE HARNESS END AND RUN THROUGH THE HARNESS TO THE FUEL PUMP COUPLER.
Consequence & remedy
Consequence: IF THE WATER REMAINS IN THE COUPLER FOR AN EXTENDED PERIOD OF TIME, THE TERMINALS CAN BECOME CORRODED, WHICH CAN PREVENT THE FUEL PUMP FROM OPERATING PROPERLY. IF THIS CORROSION AFFECTS FUEL PUMP OPERATION WHILE THE SCOOTER IS BEING RIDDEN, THERE COULD BE A CRASH RESULTING IN INJURY OR DEATH.
Remedy: DEALERS WILL INSTALL A SUB-HARNESS WHICH IS DESIGNED TO ALLOW ANY WATER BETWEEN THE WIRE HARNESS AND THE FUEL PUMP TO DRAIN OUT BEFORE IT REACHES THE FUEL PUMP. THE DEALER WILL ALSO INSPECT THE CONNECTORS. IF EITHER THE MAIN WIRE HARNESS CONNECTOR OR THE FUEL PUMP CONNECTORS IS ALREADY CORRODED, THE CORRESPONDING ASSEMBLY(IES) WILL ALSO BE REPLACED. THE RECALL BEGAN ON MAY 9, 2008. OWNERS MAY CONTACT YAMAHA AT 1-800-962-7926.
ON CERTAIN MOTORCYCLES, A LEAK AT THE FUEL PUMP SEAL MAY ALLOW FUEL LEAKAGE.
Consequence & remedy
Consequence: FUEL LEAKAGE, IN THE PRESENCE OF AN IGNITION SOURCE, COULD RESULT IN A FIRE.
Remedy: DEALERS WILL REPLACE THE FUEL PUMP SEAL FREE OF CHARGE. THE RECALL BEGAN ON JUNE 18, 2007. OWNERS MAY CONTACT YAMAHA AT 1-800-962-7926.
