YAMAHA Complaints

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

IN HOT WEATHER, THE YAMAHA YP400 FAILS TO START, STALLS AT IDLE, AND INTERMITTENTLY CUTS FUEL AT HIGH SPEED. SYMPTOMS ARE NONEXISTENT UNTIL THE AIR TEMPERATURE EXCEEDS ABOUT 95 DEGREES F. SIMILAR PROBLEMS WITH THE FUEL PUMPS ARE FREQUENTLY DOCUMENTED WITH OWNERS OF MAJESTY YP400 MODELS AS WELL AS T-MAX XP500 AND ZUMA YW125, THE LAST OF WHICH WAS SUBJECT TO A RECALL OF ITS OWN. *TR

TL* THE CONTACT OWNS A 2002 YAMAHA ROAD STAR SILVERADO MOTORCYCLE. THE CONTACT STATED THAT WHILE DRIVING AT AN UNKNOWN SPEED, THE ENGINE RPMS INCREASED ABNORMLLY AND THE REAR WHEEL SEIZED. THE MOTORCYCLE WAS TAKEN TO AN INDEPENDENT MECHANIC BUT WAS NOT DIAGNOSED TO DETERMINE THE FAILURE. THE MANUFACTURER WAS NOT MADE AWARE OF THE FAILURE. THE VEHICLE WAS NOT REPAIRED. THE FAILURE AND CURRENT MILEAGE WAS 53,000. THE VIN WAS NOT AVAILABLE.

TL* THE CONTACT OWNS A 2006 YAMAHA STRATOLINER. THE CONTACT STATED THAT WHILE DRIVING APPROXIMATELY 40 MPH, THERE WAS AN ABNORMAL NOISE WHEN IN THIRD GEAR. IN ADDITION, THE CONTACT STATED THAT WHEN THE BRAKE PEDAL WAS DEPRESSED THE VEHICLE WOULD STALL. THE VEHICLE WAS ABLE TO RESTART HOWEVER, THE FAILURE RECURRED MULTIPLE TIMES. THE VEHICLE WAS NOT DIAGNOSED OR REPAIRED. THE MANUFACTURER WAS NOT NOTIFIED OF THE FAILURE. THE APPROXIMATE FAILURE MILEAGE WAS 30,000.

IT IS VERY HARD TO SEE THE SPEEDOMETER DURING THE DAY. ESPECIALLY, WHEN THE SUN IS RISING OR SETTING. IF IT'S THE MIDDLE PART OF THE DAY IT BECOMES DIFFICULT ONCE I HAVE SUNGLASSES ON. *TR

SPEEDOMETER READOUT IS EXTREMELY DIFFICULT TO SEE IN SUNLIGHT AND IMPOSSIBLE TO SEE IF WEARING POLARIZED SUNGLASSES. I HAVE TO TAKE MY EYES OFF THE ROAD AND ADJUST MY VIEWING ANGLE TO DETERMINE HOW FAST I'M GOING, THIS PRACTICE FORCED ON ME BY THE DESIGN OF THE ELECTRONIC SPEEDOMETER IS VERY DISTRACTING AND DANGEROUS. *TR

AT INITIAL COLD START AND UNDER LOAD BETWEEN 3000-4000 RPM THERE IS A NOTICEABLE RATTLE/TICK FROM THE RIGHT SIDE OF ENGINE AT THE CAM CHAIN TENSIONER. UPON FURTHER INSPECTION IT SEEMS THE TENSIONER DOES NOT HOLD TENSION WHICH CAN LEAD TO PREMATURE WEAR, BREAKAGE, OR ENGINE FAILURE. FOLLOWING YAMAHA PROCEDURE FOR CAM CHAIN TENSION ADJUSTMENT PROVES THAT THE TENSIONER IS MALFUNCTIONING BY WATCHING THE HEX KEY TOOL BACK OFF (LOOSEN) AFTER MAKING ADJUSTMENT AND EVENTUALLY CAUSING RATTLE/TICK AGAIN. CONTACTING YAMAHA DEALERSHIP ALSO CONFIRMED ISSUE, BEING INFORMED THAT THERE HAVE BEEN MULTIPLE REVISIONS MADE (UPDATED PARTS) BUT STILL NO CONFIRMATION ON PERMANENT FIX. *TR

DRIVING 45MPH ON A FLAT BLACK TOP. SPEEDO STARTED TO BOUNCE HEARD A NOISE THAT SOUNDED LIKE GRINDING WHEN APPLYING THE CLUTCH WHILE LETTING OFF OF THE THROTTLE. A FEW MOMENTS LATER THE SPEEDO FAILED. I WAS ABLE TO DRIVE MY BIKE HOME. WHILE INVESTIGATING THE SPEEDO FAILURE AND THE SOURCE OF THE NOISE I DISCOVERED THAT THE MIDDLE DRIVE GEAR SHAFT SHEARED OFF. THE SHAFT SHEARED OFF ON THE THREADED PORTION AT THE RETAINING NUT LOCATION. IN RESEARCHING THE CAUSE OF THE FAILURE, I FOUND THAT THIS IS A COMMON FAILURE ON THESE MOTORCYCLES THAT I FEEL NEEDS TO BE ADDRESSED BY YAMAHA. *JS

CAN NOT READ SPEEDOMETER IN BRIGHT SUN. SOMETIMES DANGEROUS TO NOT KNOW HOW FAST I AM TRAVELING. *TR

UNDER MOST CIRCUMSTANCES, IT IS HARD TO READ THE SPEEDOMETER. IT REQUIRES SEVERAL SECONDS OF FOCUS TO READ IT THAT COULD LEAD TO ACCIDENTS. *TR
