2007 YAMAHA YZFR1 Power Train Problems

I ALMOST DROPPED THE BIKE WITH MY SON ON THE BIKE WITH ME IN A INTERSECTION AND WAS ALMOST STRUCK BY ANOTHER VEHICLE DUE TO THE LOAF IN THROTTLE IN FIRST GEAR. THE BIKE STUMBLES AND MISFIRES FROM IDLE UP TILL AROUND 2000 RPMS. THIS HAS HAPPENED SEVERAL TIMES. I HAVE NOTIFIED YAMAHA DIRECTLY WITH NO HELP. THEY STARTED CHANGING OUT THE COMPUTERS IN THE BIKES THEN THEY STOPPED. I JUST BOUGHT THE BIKE WITH THE EXTENDED WARRANTY. THIS IS A VERY DANGEROUS PROBLEM ESPECIALLY HAVING MY CHILD ON THE BIKE WHEN THIS TOOK PLACE. WE WERE LUCKY THAT WE BARELY WERE MISSED BY A CAR DUE TO THE BIKE STUMBLING AND SHIFT OFF IN THE INTERSECTION AS I WAS MAKING A LEFT HAND TURN. IT TOOK EVERYTHING IN ME TO PREVENT MY SON FROM BEING STRUCK BY THE ONCOMING VEHICLE. THIS IS A MAJOR PROBLEM WITH THE 07 AND...

THE 2007 YAMAHA YZF-R1 HAS SIGNIFICANT LAG OR AFLAT-SPOT" IF YOU WILL AT APPROXIMATELY 48 MPH IN SECOND GEAR. ANY ATTEMPT TO ROLL ON THE THROTTLE AT THAT POINT WILL RESULT IN THE BIKE NEARLY STALLING AND OR CUTTING OUT BEFORE SLOWLY ACCELERATING. THIS CREATES A DANGEROUS SITUATION FOR ANY OWNERS OF THE MOTORCYCLE. IF YOU EVER HAD TO ACCELERATE OUT OF A PROBLEM AT THAT SPEED, YOU MIGHT AS WELL JUST BRACE FOR IMPACT. ALSO, 45 MPH IS A VERY COMMON SPEED LIMIT IN OUR LOCAL AREA, AND IT WAS NOT A PLEASANT FEELING WHEN YOU ROLL ON THE THROTTLE AND NOTHING HAPPENS. KEEP IN MIND, MY 10 FAILURES IS JUST THE BEGINNING. IT IS 10 AND COUNTING. *AK
