ACCELERATING FROM STOP INTO A LEFT TURN AT AN INTERSECTION THE ENGINE JUST DIED AND WE ALMOST FELL BECAUSE A BUMP AND BRAKE LIKE EVENT OCCURRED WITH THE BIKE LEANING OVER FOR THE TURN, THIS WAS VERY UNSETTLING. SIMILAR EVENTS HAD OCCURRED PREVIOUSLY AFTER STARTING TO ACCELERATE FROM A STOP OR A NEAR STOP. THEY HAD OCCURRED WHEN DRIVING IN A STRAIGHT LINE AND THE ENGINE RESTARTING RIGHT UP AFTER EACH INCIDENT. THIS LAST TIME IT OCCURRED WITH THE BIKE LEANING, WITH A LITTLE HIGHER MOMENTUM BECAUSE OF A HIGHER SPEED AND IT HAPPENED AT THE WORST PLACE TO OCCUR, AT A BUSY INTERSECTION WHILE IN A BAD ANGLE. THEN ENGINE HAD ISSUES RESTARTING AGAIN SO I HAD THE BIKE PICKED UP BY A DEALER NEAR ME AND AFTER INSPECTION I WAS INFORMED THAT IT WAS A BAD FUEL PUMP, AND THAT THERE ARE A LOT OF POST IN THE WEB OF SIMILAR OCCURRENCES TO OTHER OWNERS OF YAMAHA MAJESTY 400'S. *TR

TL*THE CONTACT OWNS A 2006 YAMAHA YP400 MOTORCYCLE. THE VEHICLE WAS REPAIRED ACCORDING TO NHTSA CAMPAIGN ID NUMBER 08V180000 (FUEL SYSTEM, GASOLINE:DELIVERY:FUEL PUMP); HOWEVER, IT CONTINUES TO STALL AND SHUT OFF. THE CONTACT FEELS THAT THE ACTUAL HARNESS WAS NOT REPLACED ACCORDING TO THE REMEDY, AND WAS ONLY INSPECTED AT THE TIME OF THE REPAIR. THE MANUFACTURER INFORMED HIM TO TAKE THE VEHICLE BACK TO THE DEALER FOR FURTHER INSPECTION SINCE THE VEHICLE WAS ORIGINALLY REPAIRED UNDER RECALL. THE CONTACT INQUIRED ABOUT REPLACING THE HARNESS AND THE MANUFACTURER STATED THAT THEY WERE UNSURE IF THE HARNESS WAS REPLACED AT THE TIME OF THE RECALL REPAIR. THE DEALER WOULD HAVE TO NOTIFY THE CONTACT ONCE THE VEHICLE WAS RE-INSPECTED. THE FAILURE MILEAGE WAS 600 AND CURRENT MILEAGE WAS 25,000. UPDATED 07/24/09. *LJ
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.
