2009 YAMAHA YW125 Fuel System, Gasoline Problems

WHEN IT IS HOT OUT, THE FUEL PUMP STOPS WORKING. THIS HAPPENS ESPECIALLY WHEN IT HAS BEEN SITTING OUTSIDE IN THE SUN. IT WILL INITIALLY START AND THEN, WHEN THE BIKE GETS WARMED UP, IT JUST SHUTS OFF. THEN, WHEN YOU TRY TO START IT, YOU DO NOT HEAR THE PUMP PRESSURIZE AND IT WILL NOT START FOR ANYWHERE FROM AN HOUR TO SEVERAL HOURS. *JS

MY 2009 YAMAHA WY125YL HAS BEGUN TO STALL AND WILL NOT RESTART. I VIEW THIS AS A SERIOUS SAFETY ISSUE. PUSHING A MOTORCYCLE FROM A BUSY INTERSECTION WITH FAST MOVING TRAFFIC IS SOMETHING THAT WOULD NOT CARE TO REPEAT. AFTER A BRIEF INTERNET SEARCH I WAS QUICKLY ABLE TO FIND NUMEROUS WEBSITES FULL OF COMPLAINTS WITH THE SAME DESCRIPTION. "MOTORCYCLE STALLING, AND WILL NOT RESTART IN WARM AMBIENT CONDITIONS". *TR

MY ZUMA 125 WAS RUNNING FINE FOR ABOUT A MILE WHEN IT SUDDENLY STALLED OUT AND WOULD NOT RE-START. MY LOCAL BIKE MECHANIC SAID I HAVE A BAD FUEL PUMP. HAVE NOT RODE SCOOTER SINCE THEN BECOUSE UNABLE TO GET A FUEL PUMP. THERE WAS A RECALL OVERSEAS AND SHOULD BE ONE HERE IN THE U.S. *TT

CURRENTLY AT 1200 MILES ON ODOMETER AND EXPERIENCING SAME EXACT SYMPTOMS ALL OVER AGAIN. 3. FUEL PUMP WAS REPLACED BY DEALERSHIP. 1ST ONE WAS STILL UNDER WARRANT.... :-( *TR

2009 YAMAHA ZUMA 125CC: FUEL PUMP FAILURE...SCOOTER ONLY HAS 320 MILES!!! UPON RIDING THE 1ST 3 MILES, THE MOTOR HEATS UP AND THE FUEL PUMP QUITS. WITHOUT NOTICE, THE SCOOTER LOSES ALL POWER AND RAPIDLY DECELERATES AS THE DRIVE BELT DOES NOT DISENGAGE UNTIL BIKE SLOWS TO APPROXIMATELY 5 MPH. THIS IS EXTREMELY DANGEROUS IN CHICAGO TRAFFIC AS NOBODY CARES OR THINKS YOU MIGHT ACTUALLY BE HAVING MECHANICAL ISSUES! NOW YOU ARE STRANDED AND HAVE TO SHUT OFF ALL POWER TO THE SCOOTER AND WAIT FOR IT TO COOL DOWN. THE LONGER YOU WAIT THE FARTHER YOU WILL BE ABLE TO GO...I THINK THIS IS DUE TO THE AMOUNT OF FUEL THAT IS ABLE TO GRAVITY DRIP INTO THE GAS LINES DURING COOLDOWN. AUDIBLY, YOU CAN HEAR THE DECREASED DURATION OF THE FUEL PUMP ENGAGING UNTIL THERE IS ZERO ENGAGEMENT OF THE FUEL PUMP. REPEATING THIS SEQUENCE MIGHT GET YOU ANOTHER 1/2 MILE. NOW, YOU HAVE NO CHOICE BUT TO PUSH. THIS IS A SERIOUS SAFETY ISSUE TO ENCOUNTER IN TRAFFIC AND YAMAHA SHOULD BE EMBARRASSED TO HAVE SUCH ISSUES WITH A $3000 NEW MACHINE. *TR

WHILE WAITING AT A RED LIGHT MY SCOOTER JUST STALLED OUT AND WOULD NOT RESTART. IT WAS A HOT DAY AND AFTER LETTING MY SCOOTER COOL FOR AN HOUR OR SO IT STARTED BACK UP. SEEMS EVERY TIME IT IS 90+ DEGREES OUT THE SCOOTERS FUEL PUMP WILL FAIL AND STRAND ME IN THE MIDDLE OF TRAFFIC. AS OF THIS WRITING, YAMAHA HAS NOT ACKNOWLEDGED THAT A PROBLEM EXISTS EVEN THOUGH I HAVE BEEN HEARING OF NUMEROUS REPORTS ABOUT THIS EXACT PROBLEM FROM OTHER ZUMA 125 RIDERS. *TR

Mileage: 2,170

FUEL PUMP INTERMITTENT FAILURE TO FUNCTION IN HOT WEATHER. THIS BECAME A SAFETY HAZARD AS IT BECAME WORSE. THE SCOOTER HAD TO BE TOWED TO THE DEALER TWICE BEFORE THE DEALER WAS ABLE TO REPLICATE THE FAILURE. THE DEALER REPLACED THE FUEL PUMP AND THAT SEEMS TO HAVE CORRECTED THE PROBLEM SO FAR. THE FUEL PUMP FAILED AT 756 MILES ON THE ODOMETER. *TR

Mileage: 756

VEHICLE'S ENGINE STALLS WHILE RIDING, OR AT IDLE, UNDER NORMAL OPERATING CONDITIONS. THIS OCCURS MOST OFTEN WHEN OUTSIDE AIR TEMPERATURE IS ABOVE 85 DEGREES FAHRENHEIT. THE FIRST TIME THE VEHICLE STALLED ( ON OR AROUND 5/15/2010)I WAS STOPPED AT AN INTERSECTION AND WAS ABLE TO RESTART THE VEHICLE IMMEDIATELY. ON OR AROUND 6/18/2010 THE VEHICLE STALLED AGAIN WHILE PULLING AWAY FROM A STOP AT A LEFT TURN SIGNAL. THE VEHICLE WOULD NOT RESTART AND I HAD TO PUSH IT ACROSS THE INTERSECTION TO AN ADJACENT PARKING LOT. I WAS ABLE TO RE-START THE VEHICLE AFTER LETTING IT SIT FOR APPROXIMATELY 5 MINUTES. THE THIRD TIME THE VEHICLE STALLED (ON OR AROUND 6/28/2010) I WAS PULLING AWAY FROM A STOP AT AN INTERSECTION OF A MAJOR HIGHWAY. THE VEHICLE WOULD NOT RE-START, AND I HAD TO PUSH IT ACROSS TWO LANES OF TRAFFIC TO REACH A SIDEWALK. AFTER WAITING APPROXIMATELY FIVE MINUTES THE SCOOTER WOULD NOT RESTART, SO I PROCEEDED TO PUSH IT THE 1/4 MILE TO MY HOME. AFTER PUSHING IT FOR THREE BLOCKS I ATTEMPTED TO RESTART IT, IT STARTED, IDLED POORLY, AND STALLED AGAIN WITHOUT MY HAVING APPLIED ANY THROTTLE. I TOOK THE VEHICLE TO MY LOCAL YAMAHA SERVICE CENTER THE FOLLOWING DAY. THEY RODE AND PERFORMED DIAGNOSTICS ON THE VEHICLE, DETERMINING, ON 7/22/2010, THAT THE FUEL PUMP WAS FAULTY AFTER HAVING THE VEHICLE STALL WHILE RIDING IN TRAFFIC ( THE VEHICLE HAS BEEN AT THAT FACILITY SINCE 6/29/2010, AND IS STILL IN THEIR POSSESSION) . I AM NOW AWAITING A NEW FUEL PUMP TO ARRIVE FROM YAMAHA. *TR

THIS IS REGARDING A 2009 YAMAHA ZUMA 125 SCOOTER. THERE HAS BEEN A WIDESPREAD ISSUE WITH THE FUEL PUMPS ON THESE BIKES AND MINE FINALLY BROKE DOWN THE OTHER DAY. THE ISSUE IS THAT IF THE OUTSIDE TEMPERATURE IS HOT ENOUGH IT CAUSES THE FUEL PUMP TO COMPLETELY FAIL. LUCKILY MINE STOPPED WORKING WITH THE BIKE STATIONARY, HOWEVER IT IS COMMON TO HAPPEN WHILE THE BIKE IS MOVING WHICH CAUSES A COMPLETELY DANGEROUS SITUATION. WHEN THE FUEL PUMP FAILS IT IMMEDIATELY CUTS FUEL PRESSURE AND THE MOTORCYCLE WILL TURN OFF IMMEDIATELY. THIS COULD CAUSE A CRASH IF IT WERE TO HAPPEN WHILE GOING AROUND A TURN. YAMAHA IS AWARE OF THIS PROBLEM, BUT HAS NOT ISSUED A RECALL AND DOES NOT CARE TO DO ANYTHING ABOUT IT. THIS IS ABSOLUTELY UNACCEPTABLE. *TR
