YAMAHA Complaints

DT: THERE WAS JUST A RECALL ON THE PASSENGER SEAT BOLT BREAKING LOOSE AND COMING OFF, BUT THE MAIN DRIVER'S SEAT IS THE ONE THAT HAS THE PROBLEM. ALSO, UNDER CERTAIN CONDITIONS THE CARBURETOR AND FUEL PUMP CAN EMIT SUBSTANTIAL AMOUNTS OF GASOLINE THROUGH A CARBURETOR VENT ONTO THE HOT ENGINE CYLINDER; POTENTIALLY CAUSING FIRE AND EXPLOSION.*AK

2004 YAMAHA FZ6 5K+ MILES. WHEN CRUISING AND KEEPING THE ACCELERATOR CONSTANT, ONE EXPERIENCES SUDDEN CHANGES IN ENGINE-TO-TRANSMISSION POWER FEED: THE BIKE SUDDENLY STARTS TO ACCELERATE OR SLOW DOWN. ONE MUST COMPENSATE CONSTATNLY FOR THAT ERRATIC ENGINE BEHAVIOR, WHICH TAKES AWAY FROM PAYING ATTENTION TO THE ROAD. IF DOWNSHIFTING, UPSHIFTING OR CLUTCH DISENGAGEMENT IS PERFORMED DURING THE ENGINE FALTERING, THE RESULT IS A STALLED OUT ENGINE UNLESS SHIFTING IS PERFORMED VERY QUICKLY. STALLING OUT WHILE DOWNSHIFTING FOR A FULL STOP AT AN INTERSECTION GETS DICEY GIVEN THE AMOUNT OF OIL/WATER USUALLY FOUND AT STOP LINES AND THEIR APPROACHES. THIS PROBLEM TENDS TO APPEAR AFTER ABOUT 20-30 MINUTES OF ENGINE OPERATION AT ALL SPEEDS, TEMPERATURES OF ENGINE OPRATION. IT CLUTCH IS DISENGAGED, THE ENGINE IDELS DOWN TO 400-500 RMP (INSTEAD OF THE USUSAL 11-12K) AND INVARIABLY STALLS. STARTING THE BIKE RIGHT BACK DOES NOT ALLEVIATE THE SITUATION. THE ONLY REMEDY I WAS ABLE TO FIND WAS TO TURN THE IGNITION OF, TURN IT BACK ON (EVEN AFTER 2 SECONDS) AND START EH BIKE AGAIN. IDLING RMPS COME BACK TO NORMAL AND THE BIKE RIDES FINE AFTER THAT. TURNED BIKE INTO DEALERSHIP, REPORTING THE ABOVE SYMPTOMS ALONG WITH REPORTS OF THROTTLE POSITION SENSOR PROBLEMS REPORTED BY OTHER FZ6 RIDERS. DEALER COULD NOT REPLICATE THE PROBLEM AND SIMPLY REPLACED IOL/GAS FILTERS, AS WELL AS OIL. UPON RECEIVING THE BIKE BACK FROM THE DEALERSHIP, OF COURSE THE PROBLEM CAME BACK.

MY 1999 YAMAHA V STAR 1100 CC MOTORCYCLE HAS A STARTER PROBLEM,WHEN YOU TRY TO START THE ENGINE THE ENGINE KICKS BACK WHICH IN TURNS TWISTS THE STARTER BOLTS.I HAD BIKE IN SHOP @ DOHM'S CYCLE SHOP IN CHARLESTON WV.THEY WORKED ON IT AND SAID THE BOLTS WAS TWISTED AND THEY NEEDED REPLACED.I INSTRUCTED THEM THAT IT WOULDN'T CORRECT THE PROBLEM.AFTER THEM HAVING MY BIKE FOR APPROX 23 DAYS THEY CALLED AND SAID IT WAS FIXED.I WENT TO PICK IT UP AND AS SOON AS I STARTED IT I KNEW IT WASN'T FIXED.I PAID THEM APPROX $131.00.RODE ABOUT 1 MILE AND STOPPED TO GET GAS AND WHEN I RESTARTED IT THE BOLTS TWISTED AGAIN..I CALLED THEM ON MONDAY AND THEY SAID THEY COULDN'T FIX THE BIKE BECAUSE THEY DIDN'T KNOW WHAT WAS CAUSING PROBLEM.I HAD ALREADY FAXED THEM 10-15 PAGES ON THIS ISSUSE CONCERNING TWISTED STARTER BOLTS THAT I RESEARCHED ON INTERNET,DESCRIBING IN DETAIL WHAT THE STARTERS WAS DOING AND WHAT CAUSED IT.EVERYONE ON THE FORUM WAS COMPLAINING SAYING THAT YAMAHA HAD A PROBLEM AND WOULDN'T STAND BEHIND THEIR PRODUCT.I WAS REIMBURSED FOR THE LABOR AND TO THIS DAY THE BOLTS ARE STILL TWISTED AND IT'S NOT FIXED.

DEFECTIVE REAR TIRE ON YAMAHA MOTORCYCLE .*MR THERE WAS PROBLEM CALLED BLOOMING WITH THE REAR TIRES (CRACKING OF THE SIDEWALLS). THERE IS A TUBE INSIDE THE TIRE. THE DEALER STATED THAT LARGE AMOUNTS OF STATIC ELECTRICITY CAN CAUSE THIS PROBLEM. CONSUMER HAVE TO PAY FOR PROBLEM, THIS ID A COSTLY PROCEDURE THAT THE OWNER SHOULD NOT NEED TO INCUR, BECAUSE THE PROBLEM IS CAUSED BY A DEFECT IN THE SUPPLIED TIRE. *BF

2004 YAMAHA FZ6 13K+ MILES. DURING A SUSTAINED CRUISE, WITH A SUSTAINED RPM BETWEEN 4K AND 5K RPM, THE ENGINE BEGAN FALTERING/BOGGING DOWN AND RUNNING VERY ROUGH. ACCOMPANYING THIS ISSUE, THERE IS A MARKED SENSE OF DECELERATION UNLESS MORE THROTTLE IS APPLIED TO COMPENSATE FOR THE THE LOSS OF POWER; THE DECELERATION, AT TIMES, CAN BE QUITE SUDDEN. THIS PROBLEM TENDS TO OCCUR BEYOND 1/2 HOUR OF OPERATION. IF DOWNSHIFTING OR UPSHIFTING IS PERFORMED DURING THE ENGINE FALTERING, THE RESULT IS A STALLED OUT ENGINE UNLESS SHIFTING IS PERFORMED VERY QUICKLY. STALLING OUT WHILE DOWNSHIFTING FOR A FULL STOP AT AN INTERSECTION GETS DICEY GIVEN THE AMOUNT OF OIL/WATER USUALLY FOUND AT STOP LINES AND THEIR APPROACHES. TURNED BIKE INTO DEALERSHIP, REPORTING THE ABOVE SYMPTOMS ALONG WITH REPORTS OF THROTTLE POSITION SENSOR PROBLEMS REPORTED BY OTHER FZ6 RIDERS. DEALER COULD NOT REPLICATE THE PROBLEM AND SIMPLY REPLACED THE SPARK PLUGS. UPON RECEIVING THE BIKE BACK FROM THE DEALERSHIP, THE PROBLEM PROMPTLY RETURNED ABOUT 40 MINUTES INTO THE FIRST RIDE.

DEALERSHIP INFORMED CONSUMER THAT THE RECALL REPAIRS COULD NOT BE PERFORMED ON THE 2003 VSTAR 1100 CLASSIC UNTIL THEY WERE FINISHED REPAIRING ALL MOTORCYCLES WHICH WAS PURCHASED FROM THEIR DEARLSHIP.*MR

CONSUMER STATES: WHEN YOU TURN THE STEERING WILL JERK TO THE RIGHT SUDDENLY, MOSTLY TO THE LEFT SIDE BUT MOSTLY THE RIGHT, THIS IS ON A 1999 CHEVY TAHOE

TPS CAUSING STALLING AND ERRATIC IDLE. PROBLEM OCCURS MORE WHEN BIKE IS WARM, OFF, THEN RE-STARTED. HAVE ONLY HAD IT STALL ONCE WHILE RIDING. HAPPENS MORE OFTEN AS ABOVE. *AK

AT ABOUT 6200 MILES WHILE PULLING UP TO A LIGHT OF A STEADY RUN MY MOTORCYCLE WOULD DIE. RESTART IT, AND IT WOULD BE MISFIRE REAL BADLY AND DIE AGAIN. TAKE KEY OUT AND BACK IN IT WOULD FIRE UP JUST FINE, FOR THE TIME BEING. FIRST TIME THIS HAPPENED I WAS ABOUT TO TAKE A TURN, HAD THE CLUTCH IN DOWN SHIFT, THEN BRAKED FOR AN ONCOMING CAR, AS I STARTED TO LEAN I WAS LETTING THE CLUTCH OUT, WHEN LOW AND BEHOLD THE ENGINE DIED. SO IT JUST LOCKED UP. LUCKILY, I WAS ABLE TO GET THAT CLUTCH IN BEFORE IT WENT OVER. TOOK IT TO THE DEALER AND THEY HAD IT A COUPLE DAYS AND SAID THERE WERE NO CODES, AND THEY COULD NOT DUPLICATE THE COMPLAINT. IT ACTED UP WHEN EVER IT FELT LIKE. SOMETIMES IT RAN FINE FOR WEEKS, THEN SOMETIMES IT MESSES UP A BUNCH IN 1 WEEK. I'VE RESEARCHED THIS TOPIC ONLINE, AND FOUND MANY OTHERS WITH SAME PROBLEM. *AK

1. BIKE WAS BADLY HESITATING STARTING OFF IN 1ST GEAR FROM A STOP. 2. TURNING THE THROTTLE TO ACCELERATE WOULD SOMETIMES PITCH ME FORWARD ON THE START AS THE ENGINE HESITATED, THEN TURNING IT A BIT MORE WOULD ALMOST THROW ME OFF AS IT ACCELERATED. 3. ONE DEALERSHIP TRIED ADJUSTING THE THROTTLE POSITION SENSOR (TPS) AND IT ACTUALLY MADE THE PROBLEM WORSE. THE NEXT DEALERSHIP REPLACED THE TPS UNIT AND IT HAS BEEN RUNNING FINE SINCE. *AK
