YAMAHA Complaints

YAMAHA ROAD STAR WARRIOR ENGINE STALLED ON HIGHWAY EXAMINATION REVEALED A CUT OFF WIRE FROM CPS TIMING SENSOR. WIRE'S ARE UNDER GREAT TENSION. *NM

I AM POSTING THIS COMPLAINT IN CONJUNCTION WITH ANOTHER POSTED ABOUT THE YAMAHA R6 MOTORCYCLE. MINE WAS A 2003 AND I BELIEVE MOST OF THE ISSUES ARE WITH THIS YEAR. THE BIKE SHUT OFF WHILE RIDING WHEN PULLING IN THE CLUTCH OR LETTING THE RPM'S DIP LOW WHEN COMING TO A STOP - BELOW ABOUT 2500. BIKE SHOULD HAVE IDLED EASILY AROUND 1500. IT WAS IN THE SHOP 3 TIMES AND NO DEALER COULD FIGURE IT OUT. WE CALLED YAMAHA AND THEY SAID THEY'D NEVER HEARD OF IT . NOT TRUE. PLEASE SEE THIS WEBSITE: HTTP://WWW.R6MESSAGENET.COM/FORUMS/SHOWTHREAD.PHP?T=30990&HIGHLIGHT=NHTSA AND HTTP://WWW.R6MESSAGENET.COM/FORUMS/SHOWTHREAD.PHP?T=1513&HIGHLIGHT=NHTSA FOR DETAILS ON MANY OTHER RIDERS HAVING THE SAME PROBLEM - AND YAMAHA DENIES THEY EVER HEARD OF IT. MANY OTHERS HAVE CALLED THEM WITH THE SAME PROBLEM. THIS IS A SERIOUS SAFETY ISSUE AND SOMEBODY IS GOING TO GET KILLED. I FINALLY TRADED IT IN BECAUSE IT IS NOT SAFE. IT HAD HAPPENED TO ME MULTIPLE TIMES OVER THE LAST TWO YEARS. THE LAST DATE REPORTED WAS THE LAST TIME I BROUGHT IT INTO THE DEALER (APPROXIMATE DATE). *JB

I WAS RIDING HOME ON MY 2005 YAMAHA FZ6 MOTORCYCLE, WHEN THE ENGINE BEGAN IDLING VERY ROUGH. I HAD TO ROLL ON THE THROTTLE TO KEEP THE ENGINE FROM STALLING. THEN A FEW SECONDS LATER I PULLED IN THE CLUTCH AND THE ENGINE STALLED COMPLETELY. I WAS NOT ABLE TO RESTART THE ENGINE AFTER 4 ATTEMPTS. THEN I TURNED THE IGNITION OFF, AND TURNED IT BACK ON, AND THE ENGINE STARTED AS IF THERE WAS NO PROBLEM. OBVIOUSLY, TURNING THE IGNITION OFF AND BACK ON IS MERELY A BAND AID FOR THIS ISSUE, AND NOT A PERMANENT SOLUTION. PLEASE REFER TO THIS WEBSITE TO LEARN OF OTHER FZ6 OWNERS THAT HAVE EXPERIENCED THIS ISSUE. HTTP://FORUMS.SPORTBIKES.NET/FORUMS/SHOWTHREAD.PHP?T=7320 *JB

2005 YAMAHA MAJESTY FLUTTERS, STALL AND TURNS ITSELF OFF PERIODICALLY WITH NO WARNING. THIS PROBLEM IS BEING REPORTED ON THE YAMAHA MAJESTY CHAT ROOMS ESPECIALLY YAHOO. I CONTACTED YAMAHA OF AMERICA AND THEY STATED NO PROBLEM HAS BEEN REPORTED. THE CHAT ROOMS HOWEVER REFLECT THAT YAMAHA HAS RECOGNIZED A PROBLEM WITH SOME OF THE SCOOTERS BECAUSE THEY HAVE REPLACED FAULTY ECU IN 2006 BIKES UNDER WARRANTY. THE PROBLEM EXTENDS BEYOND 2006 AS MY SCOOTER IS A 2005 AS ARE OTHERS BEING REPORTED IN THE CHAT ROOMS. THIS PROBLEM OCCURS WITHOUT NOTICE AND WHILE THE BIKE IS MOVING AND SOONER OR LATER WILL CAUSE AN ACCIDENT. I BOUGHT THE SCOOTER USED AND THE STALLING OCCURRED THE SECOND WEEK I HAD THE BIKE. I HAVE CONTACTED THE PREVIOUS OWNER TO SEE IF HE HAD A PROBLEM. THE MAJESTY CHAT ROOMS ESPECIALLY YAHOO REPORTS MANY OTHERS WITH THIS PROBLEM. MOST OF THE TIME IT IS AT LOW SPEEDS AFTER A STOP AND MAKING A TURN. *JB

THE 2004 YAMAHA R1 STARTS SHAKING AND BACKFIRING. WHEN THE CLUTCH IS PULLED IN THE ENGINE DIES. ON MULTIPLE OCCASIONS WHILE RIDING THE ENGINE HAS STOPPED RESULTING IN MANY NEAR CRASHES. THE ONLY WAY TO FIX THE PROBLEM IS TO TURN THE KEY ON AND OFF AGAIN. THIS BIKE IS UNSAFE. THERE ARE NUMEROUS COMPLAINTS ABOUT THIS FROM MANY PEOPLE AND YAMAHA IS DOING NOTHING. *NM

AT 9M MILES, MY 2004 YAMAHA FZ6 BEGAN TO EXHIBIT THE FOLLOWING: 1) AFTER APPROXIMATELY 30 MINUTES OF OPERATION, ERRATIC AND PROLONGED PERIODS OF ROUGH IDLE AT 500 RPMS INSTEAD OF THE NORMAL 1300 RPMS 2) MOTOR WOULD STALL DURING GEAR CHANGES, EVEN AT HIGHWAY SPEEDS 3) DURING THESE TIMES, THE SMELL OF GASOLINE WAS NOTICEABLE. CHANGING THE SPARK PLUGS SEEMED TO FIX THE PROBLEM TEMPORARILY, BUT THEY SOON REAPPEARED. AT 12M MILES, THE BIKE WAS TAKEN TO THE YAMAHA DEALER TO BE FIXED BUT THEY COULD FIND NOTHING WRONG WITH IT. I WENT NEXT TO AN INDEPENDENT MOTORCYCLE MECHANIC WHO ALSO COULD FIND NOTHING WRONG. HE SUGGESTED THAT IT WAS PROBABLY AN ELECTRICAL PROBLEM AND COULD BE EXPENSIVE TO FIX AND I SHOULD TAKE IT TO A DIFFERENT DEALER. HE ALSO QUESTIONED IF THE "CHECK-ENGINE" LIGHT HAD COME ON WHICH WOULD HAVE REGISTERED SPECIFIC TROUBLE CODES, BUT I TOLD HIM THAT THEY HAD NOT. AT 12800 MILES, WHILE PULLING ONTO THE ROADWAY, THE BIKE STALLED UNEXPECTEDLY IN A TURN AT LOW SPEED, LOCKED THE BACK TIRE AND WENT DOWN. I SUSTAINED MINOR INJURIES, AND THE BIKE LOST A MIRROR, FOOT PEG, FRONT FAIRING, AND GENERALLY GOT BUMMED UP. SINCE THEN, I HAVE FOUND NUMEROUS REPORTS OF "THROTTLE POSITIONING SENSOR" DEFECTS THAT HAVE CREATED SIMILAR PROBLEMS WITH THIS MAKE AND MODEL OF MOTORCYCLE. AND YET, THE DEALERS SEEM TO KNOW NOTHING ABOUT IT! INSTALLING A NEW TPS MAY OR MAY NOT FIX THE PROBLEM. BUT FOR NOW I'M STUCK WITH A BIKE THAT I CAN'T TRUST, HAS LITTLE RESALE OR TRADE-IN VALUE, AND PROBABLY ISN'T SAFE TO RIDE. AFTER READING THE NUMEROUS AND SIMILAR SOUNDING COMPLAINTS, THIS MAY WELL BE A MANUFACTURING DEFECT THAT SHOULD RESULT IN A RECALL. *NM

I HAD MY 2004 YAMAHA R1 REPEATEDLY LOSE POWER WHILE OPERATING IN THE SUB-7000 RPM RANGE. THE MOTORCYCLE WOULD BACKFIRE, SPUTTER, AND THEN LOSE POWER. THE FAILURE FIRST APPEARED WITH APPROXIMATELY 7000 MILES ON THE ODOMETER. THE FAILURE WAS CORRECTED BY REMOVING THE THROTTLE POSITION SENSORS AND CLEANING THEM WITH CONTACT CLEANER. THE CLEANING WAS DONE APPROXIMATELY 2500 MILES AGO AND THE FAILURE HAS NOT REAPPEARED. *JB

I AM AWARE OF SEVERAL DOZEN PEOPLE WHO HAVE HAD THE SAME PROBLEM I AM NOW HAVING WITH FAILURE OF THE THROTTLE POSITION SENSOR (TPS) ON A 2004-2005 YAMAHA FZ6. THIS CAUSES A NEW VEHICLE TO RUN POORLY AND STALL FREQUENTLY UNTIL THE PART IS REPLACED. *JB

DT*: THE CONTACT STATED WHILE DRIVING 65 MPH THE MOTORCYCLE STARTED WOBBLING WITHOUT WARNING. THE VEHICLE WAS MOVED OFF THE ROAD AND TOWED TO AN INDEPENDENT REPAIR SHOP WHERE IT WAS DETERMINED THE SPOKES WERE LOOSE ON THE REAR RIM. THE INDEPENDENT MECHANIC RECOMMENDED TAKING THE MOTORCYCLE TO A SERVICE DEALER FOR INSPECTION, BUT NO ARRANGEMENTS HAVE BEEN MADE WITH THE DEALER.

DT*: THE CONTACT STATED WHILE DRIVING 55MPH EIGHTEEN OF THE REAR WHEEL SPOKES SNAPPED. ALTHOUGH, THE VEHICLE WOBBLED IT WAS DRIVEN SAFELY FROM THE ROAD. THE SHORT SPOKES BECAME LOOSE PRIOR TO THE INCIDENT AND WERE TIGHTENED AT AN INDEPENDENT REPAIR SHOP. AFTER THE INCIDENT THE WHEEL WAS REPLACED BY THE MECHANIC. *AK
