YAMAHA Complaints

WHILE TRAVELING AT APPROXIMATELY 45 MPH THROUGH CURVES AND HILLS, WITH VARIOUS LEVELS OF LOAD ON THE ENGINE AND DRIVE TRAIN, A LOUD BUZZING/WHINING NOISE WAS BEING PRODUCED FROM THE ENGINE AREA ACCOMPANIED WITH SPEEDOMETER FAILURE WHEN ENGINE AND TRANSMISSION WERE PUT UNDER LOAD. WHEN ENGINE AND DRIVE TRAIN WERE UNDER NO LOAD (COASTING), THE SPEEDOMETER WOULD OPERATE NORMALLY. INSPECTION OF ENGINE/TRANSMISSION AND FINAL DRIVE FLUIDS REVEALED EVERYTHING TO BE WITHIN SPECIFICATIONS. WHEN THE MOTORCYCLE WAS RESTARTED AND OPERATED AGAIN, THERE WAS NO NOISE PRODUCED AND APPEARED TO OPERATE NORMALLY. THREE MONTHS LATER THE SAME ISSUE PRESENTED ITSELF WITH THE SAME SYMPTOMS, BUT WENT AWAY AFTER INSPECTING THE MOTORCYCLE. TWO MONTHS LATER, THE ISSUE HAPPENED AGAIN AND THE MOTORCYCLE WAS TAKEN TO A MECHANIC. THE MECHANIC DISCOVERED THAT THE NUT HOLDING THE YOKE TO THE MIDDLE DRIVE SHAFT/PINION GEAR HAD LOOSENED APPROXIMATELY THREE THREADS. *TR

HEADLIGHTS FAILED WITHOUT WARNING. POTENTIALLY LIFE THREATENING AS THIS OCCURRED WHILE UNDERWAY AT NIGHT. THE DEFECT OCCURRED IN WHAT IS KNOWN AS THE S6 SPIDER - A SPIDER BEING A GROUND WIRE COLLECTOR CIRCUIT ON THE VEHICLE. THE VEHICLE HAS ALREADY BEEN RECALLED FOR OTHER SPIDER FAILURES, BUT THE SPIDER AFFECTED BY THIS PROBLEM WAS NOT AMONG THE ONES DEALT WITH. *TR

SEVERAL TIMES UPON COMING TO A STOP OR COASTING THE ENGINE DIES. THIS EVEN HAPPENED AFTER A SERVICE! THE PROBLEM SEEMS TO BE GETTING WORSE. VERY DANGEROUS AS I TRAVEL HOUSTON STREETS AND HIGHWAYS DAILY. I HAVE COMMUNICATED WITH OTHER STRATOLINER OWNERS AND THIS APPEARS TO BE A GROWING PROBLEM. IS THERE A KNOWN DEFECT? *TR

AFTER A BRIEF WARM UP, ENGINE STALLED AND WOULD NOT RESTART. NO SPARK CONDITION. WILL RESTART WHEN COOL, THEN THE PROBLEM REPEATS. A CRASH WAS AVOIDED. *TR

AS I WAS RIDING, SHIFTING GEARS I HEAR A NOISE COMING FROM THE ENGINE AREA ON 3RD GEAR, , NOW IS MORE EVIDENT THATS THE SOMETHING AFTER ABOUT 60 MILES AND LOUDER NOISE WILE ON 3RD GEAR THAT SOMETHING IS WRONG, NOW AFTER A LIGHT INTERNET RESEARCH, IS A KNOWN ISSUE ON THIS PARTICULAR YEAR AND MODEL OF A BIKE. *TR

TL* THE CONTACT OWNS A 2001 YAMAHA YZFR6 MOTORCYCLE. THE CONTACT STATED THAT THE CUSTOM OF THE FRAME WAS NOT SECURE. THE MANUFACTURER WAS NOT MADE AWARE OF THE PROBLEM. THE APPROXIMATE FAILURE MILEAGE WAS 27,000. UPDATED 2/11/14*CN THE CONSUMER STATED WHEN HE RETRIEVED THE MOTORCYCLE FROM THE REPAIR SHOP, THE WELDING WAS INCOMPLETE AND WAS NOT ADJUSTED PROPERLY.

DRIVING ACROSS THE INTERSTATE10 SALT RIVER BRIDGE IN PHOENIX AZ, THERE IS A DIP AT ONE OF THE BRIDGE EXPANSION JOINTS. IT IS NOT A VERY SEVERE DIP BUT THE REAR SUSPENSION ON THIS NEW MOTORCYCLE BOUNCED VIOLENTLY 5 TIMES AFTER THIS DIP. THERE IS AN ADJUSTMENT SCREW TO INCREASE THE DAMPING AND I TURNED IT TO THE MAXIMUM VALUE, BOTH FRONT AND REAR, THIS REDUCED THE AMOUNT OF POST BUMP BOUNCING TO AROUND 2 TIMES. THIS IS INADEQUATE SUSPENSION DAMPING AND I BELIEVE IT COULD BE A HAZARD, ESPECIALLY IF IT HAPPENS IN A TURN, WITH AN INEXPERIENCED RIDER. I AM BUYING A DIFFERENT REAR SHOCK FOR THIS MOTORCYCLE, BUT NOT EVERYBODY HAS THAT ABILITY AND A NEW REAR SHOCK IS NOT CHEAP OR EASY TO INSTALL. I AM ALSO CHANGING THE FRONT FORK OIL TO A HIGHER VISCOSITY, TO STOP THE FRONT END FROM OVER RE-BOUNDING. AT THE VERY MINIMUM, I RECOMMEND THAT ALL NEW MOTORCYCLES SHOULD LEAVE THE DEALERSHIPS WITH THE SUSPENSION ADJUSTERS SET TO MAXIMUM VALUE, FRONT AND REAR TO REDUCE THIS PROBLEM. *TR

ONCE ENGINE WAS WARMED UP, VEHICLE STALLED AT STOPLIGHTS TWICE AND ONCE WHEN STARTING TO MOVE AFTER A STOP (WHEN IN AN INTERSECTION). OTHER TIMES WHEN STOPPED. IDLE SPEED DROPPED BELOW 1400, UNDER WHICH IT STALLS, AND IT WAS DIFFICULT TO REV THE ENGINE TO PREVENT STALLING SINCE THERE IS NO NEUTRAL GEAR, SO REVVING MORE THAN SLIGHTLY CAN MAKE THE VEHICLE MOVE. *TR

YZF R1 STALLS OUT WHEN ENGINE TEMPERATURE IN LESS THAN 170 DEGREES. WHILE APPROACHING FIRST STOP, SHIFTING TO NEUTRAL IT STALLS OUT REGULARLY. EXTREMELY HIGH IDLE (JUMPS FROM 1000 TO 3000 RPM) WHEN ENGINE TEMPERATURE EXCEEDS 200 DEGREES. REPLACED THROTTLE POSITION SENSOR, SUB-WIRING HARNESS, ADJUSTED THE THROTTLE BODIES. STILL STALLS OUT. *TR

PURCHASED MOTORCYCLE ON 12.6.13, ON THE DRIVE HOME REALIZED THAT THE SPEEDOMETER WAS UNREADABLE. IT WAS DAYLIGHT, MID-DAY. SUN WAS BRIGHT. I WAS UNABLE TO READ MY SPEED. IT'S A DIGITAL INDICATOR, WITH SMOKED LENS. WHEN RESEARCHING REVIEWS, THE ONLY COMPLAINT REGISTERED WAS THE INABILITY TO SEE THE SPEEDOMETER READINGS. THE COMPANY HAS TO BE AWARE OF THIS, AND SHOULD BE REQUIRED TO MAKE THE NECESSARY RECALL ADJUSTMENTS. OTHERWISE, THIS SAFETY ISSUE MIGHT NOT BE CORRECTED. *TR
