2006 Yamaha XVS1100

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

TL* THE CONTACT OWNS A 2006 YAMAHA 1100 SILVERADO MOTORCYCLE. THE CONTACT STATED THAT WHILE DRIVING 30 MPH, AN ABNORMAL NOISE WAS HEARD FROM THE REAR OF THE VEHICLE. THE VEHICLE THEN LOST ALL POWER BUT DID NOT STALL. THE CONTACT TOOK THE VEHICLE TO THE DEALER WHERE IT WAS DETERMINED THAT THE DRIVE SHAFT HAD BECOME SHREDDED. THE VEHICLE WAS NOT REPAIRED. THE FAILURE AND CURRENT MILEAGES WERE 12,000. UPDATED 09/05/13*LJ THE CONSUMER STATED THE DRIVE SHAFT SHEARED IN HALF/

I HAD JUST STARTED OUT FROM A STOP, SHIFTED TO SECOND GEAR WHEN THE BIKE STARTED TO CLATTER. AS I HAD BEEN STOPPED AT THE LOCAL MOTORCYCLE REPAIR SHOP, I RETURNED THERE AND LEFT THE MOTORCYCLE. THE NEXT DAY I CALLED THE SHOP AND HAD THE MECHANIC CHECK THE BIKE OUT. HE TOLD ME THAT THE MIDDLE DRIVE SHAFT HAD COME APART. UPON FURTHER INSPECTION IT WAS FOUND THE SHAFT HAD BROKEN BEHIND THE RETAING NUT FOR THE UNIVERSAL JOINT. THIS PROBLEM HAS BEEN REPORTED ON SEVERAL YEAR MODEL'S OF THIS MOTORCYCLE (YAMAHA V-STAR-1100) COMPLAINT'S TO NHTSA. SEVERAL REPORTS OF REAR WHEEL LOCKING UP WHEN THIS HAPPENS HAVE BEEN SUBMITED. THERE IS ONE REPORT ON 04/24/2006 OF A PERSON HAVING THE SAME PROBLEM WHERE THE REAR WHEEL HAD LOCKED UP PRIOR TO A CRASH IN WHICH SHE WAS REAR-ENDED AND KILLED. IT IS UNKNKWN IF THE REAR WHEEL LOCKING UP BECAUSE OF A BROKEN MIDDLE SHAFT CAUSED THIS ACCIDENT, BUT I WOULD BE SUSPECT OF THIS. I HAVE BEEN IN CONTACT WITH YAMAHA, AND THEY HAV NOT ISSUED A RECALL FOR THIS BUT THEY HAVE CHANGED THE MANFACTURE OF THIS PART, WHICH WOULD INDICATE THAT THEY WERE AWARE FO A PROBLEM. AS THE COST OF REPAIR FOR THIS DEFECTIVE PART IS IN THE RANGE OF $2500.00 TO $3500.00 AND THE POTENTIAL FOR SEVERE INJURY OR DEATH FROM THE PART FAILURE, THE COMPANY SHOULD RECALL AND REPLACE THIS ON ALL MODELS AFFECTED BY IT. *TR

WHILE RIDING, I BEGAN TO HEAR A WHINING OR SIREN LIKE NOISE WHILE DECELERATING. WHEN I GOT HOME I EXPLORED WHERE THE NOISE SEEMED TO COME FROM AND FOUND WHEN LOOKING THROUGH THE PASSAGE WHERE THE SPEED SENSOR IS MOUNTED THAT THE NUT HAD COME OFF OF THE MIDDLE GEAR BECAUSE IT HAD NOT BEEN STAKED PROPERLY AND WAS NOT PROPERLY SECURED. FURTHERMORE IT HAS NO SAFETY, KEY, RETAINER, COTTER PIN, OR ANY OTHER DEVICE DESIGNED TO RETAIN IT SHOULD SOMETHING GO WRONG, AS IT DID IN MY CASE, AND SO SEEMS TO BE IMPROPERLY ENGINEERED OR AT THE VERY LEAST INCOMPETENTLY INSTALLED FROM THE MANUFACTURER. *TR
