Yamaha FZ6 problems and owner complaints

1-AVERAGE USAGE, 2-MOTORCYCLES WOULD STALL SPORADICALLY, RPMS WOULD VARY CONSIDERABLY, A LOT OF HESITATION, VARIABLE IDLING, BAD GAS CONSUMPTION.

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.

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…

1) EXHAUST PIPE TURNS RED AFTER NORMAL USE, GAS TANK VENT LINE IS ABOVE EXHAUST PIPE, BACK FIRES 2) FIRE HAZARD 3) TAKEN TO SHOP AND YAMAHA COULD NOT RECREATE PROBLEM AND I WAS CHARGED FOR DIAGNOSIS - THE PROBLEM STILL EXISTS YAMAHA DOES NOT ACKNOWLEDGE THAT THEIR IS A PROBLEM WITH THIS ATV - THEY COULD NOT RECREATE THE PROBLEM AND THEREFORE ASSUME IT DOES NOT EXIST, THIS ATV HAS DONE THIS SINCE I BROUGHT IT HOME NEW FROM THE DEALER.
