Owner report 10118064 · 2005-04-18 (April 18, 2005)
1-AVERAGE USAGE, 2-MOTORCYCLES WOULD STALL SPORADICALLY, RPMS WOULD VARY CONSIDERABLY, A LOT OF HESITATION, VARIABLE IDLING, BAD GAS CONSUMPTION. A FAILURE OF THE MOTORCYCLE TO CEASE THROTTLE OPERATIONS THROUGH MID-CORNER DURING A TURN WOULD INEVITABLY CAUSE THE MOTORCYCLE AND ITS RIDER TO LOSE TRACTION AT THE REAR WHEELS. FURTHER CONSEQUENCES WOULD BE DEATH TO THE RIDER IN EXTREME, BUT HIGHLY LIKELY CIRCUMSTANCES. 3-THERE WAS A DEFECTIVE THROTTLE POSITIONING SENSOR WITH THE 2004-2005 YAMAHA FZ6 MOTORCYCLES. YAMAHA HAS SO FAR FAILED TO AN…

Owner report 10118434 · 2005-04-25 (April 25, 2005)
IDLE SUDDENLY GETS ROUGH THEN ENGINE QUITS/STALLS AT RANDOM TIMES, MOST OFTEN AT LOW SPEED AFTER DOWNSHIFTING, BUT HAS HAPPENED AT HIGHWAY SPEEDS ON PARKWAY IN TRAFFIC. I'M INVOLVED WITH AN ONLINE USERS GROUP OF FZ6 OWNERS (ABOUT 100-150 IN THE GROUP) AND ABOUT 20 - 25 PEOPLE HAVE HAD TO GET THE THROTTLE POSITION SENSOR (TPS) REPLACED TO CORRECT THE PROBLEM. (WITHIN THE 1ST YEAR OF OWNERSHIP) I BELIEVE MY BIKE IS STARTING TO EXHIBIT SOME OF THE SAME CHARACTERISTICS THEY ALL HAD AND FEEL YAMAHA SHOULD LOOK INTO THIS FOR A RECALL BEFORE SO…

Owner report 10118576 · 2005-04-27 (April 27, 2005)
1) AT APPROXIMATELY 8000 MILES ON THE ODOMETER, MY YAMAHA FZ6 BEGAN EXHIBITING PERIODIC STALLING. WHEN UNDER NORMAL POWER, THE BIKE EXHIBITED A MODERATE LOSS OF POWER, WITH A COMPLETE ENGINE STALL ONCE THE CLUTCH WAS DISENGAGED (WHILE STOPPING IN TRAFFIC OR PARKING). THESE SYMPTOMS INCREASED IN FREQUENCY UNTIL IT WAS HAPPENING SEVERAL TIMES PER DAY. 2) THE CONSEQUENCES OF THE FAILURE WERE GENERALLY MINIMAL, WITH THE EXCEPTION OF STALLING IN STOP-AND-GO TRAFFIC. ON MORE THAN ONE OCCASION, THE STALLING PREVENTED ME FROM MOVING WHEN TRAFFIC …

Owner report 10118618 · 2005-04-28 (April 28, 2005)
MY MOTORCYCLE WILL STALL AND/OR RUN ROUGH OCCASIONALLY, AND NOT IDLE WITHOUT ADDITIONAL THROTTLE INPUT. IF I TURN THE IGNITION OFF AND RESTART THE MOTORCYCLE IT WILL FIX THE PROBLEM FOR A PERIOD OF TIME. I AM VERY CONCERNED THAT THE MOTORCYCLE WILL ENCOUNTER THIS PROBLEM WHILE TURNING AND CAUSING INSTABILITY THAT MIGHT CONTRIBUTE TO A CRASH. IN ADDITION, I DO NOT LIKE HAVING THE THOUGHT OF THIS PROBLEM IN MY MIND EVERYTIME I AM RIDING, AS IT TAKES ENOUGH CONCENTRATION TO AVOID OTHER VEHICLES AND MONITOR ROAD CONDITIONS. I HAVE NOT REPAIRED TH…

Owner report 10118730 · 2005-04-30 (April 30, 2005)
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

Owner report 10118760 · 2005-04-30 (April 30, 2005)
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 THE…
