YAMAHA 2004 FZ6 BIKE RUNS GOOD FOR A WHILE, AND ALL THE SUDDEN THE ENGINE LOSES 90 % OF ITS POWER, I HAVE TO TURN THE KEY OFF, THEN BACK ON TO REGAIN POWER WHILE IN TRAFFIC, ONE TIME THIS HAPPEN I GAVE IT TO MUCH GAS TO GET OUT OF TRAFFIC ,AND I FLIPPED THE BIKE OVER IN THE MIDDLE OF THE STREET. IT WAS MY LUCKY DAY NOBODY RAN OVER ME. LOOKING AT THIS WEB SITE , THERE IS A LOT OF OTHER FZ6 RIDERS WITH THE SAME PROBLEM, I HAVE ASKED 4 YAMAHA DEALERS IF ANYONE ELSE IS HAVING THIS PROBLEM AND THEY ALL SAID NO? WELL THEY SURE DO BY LOOKING ON THIS WEB,I HAVE THE EXACT SAME PROBLEMS AS THOUGH OTHERS ON THIS SITE, AND A FACTORY RECALL IS NEEDED! SOMEONE GOING TO DIE IF NOT ALREADY THAT WE KNOW OF BECAUSE OF THIS PROBLEM. *NM
