2004 Yamaha YZF-R1

I AM AN OWNER OF A 2004 YAMAHA R1 MOTORCYCLE. WHILE I WAS RIDING HOME MID DAY ON APRIL 11 2005 I NOTICED THE BIKE IDLING VERY LOW EVERY TIME I STOPPED. SO I WENT IN TO A PARKING AREA AND SHUT THE ENGINE OFF WITH THE IGNITION KEY AND WAITED FOR APPROXIMATELY 1 MINUTE. IT SEEMED TO WORK FINE SO I PRESSED ON HOME. BUT WHEN I WAS ON THE ROAD TAKING A LEFT HAND TURN AND I CAME TO THE APEX OF THE TURN THE BIKE SHUT OFF UPSETTING THE SUSPENSION AND CAUSING ME TO LOW SIDE (DROPPING THE BIKE ON THE SIDE THAT IT WAS LEANED AS I TURNED) I HAD NO MAJOR INJURIES WITH THE EXCEPTION OF KNEE SORENESS FOR ABOUT A MONTH. THE BIKE SUSTAINED THE FOLLOWING DAMAGE: BENT FORKS, BENT FRONT WHEEL, DENTED GAS TANK, BROKEN MIRRORS, BROKEN WINDSCREEN, BROKEN UPPER FAIRING, BROKEN REAR FAIRING, DAMAGED MID LEFT FAIRING AND LOWER FAIRING, AS WELL AS BENT LEFT CLUTCH LEVER. WHEN I SPOKE TO THE DEALER THEY SAID THAT THE PROBLEM WAS ME AND NOT THE BIKE. I EXPLAINED OF THE CUTTING OFF WITH THE ENGINE AND THEY AGAIN SAID THAT IT WAS ME AND NOT THE BIKE. ONE OF THE ISSUES WITH THIS IS THAT YOU NEVER KNOW WHEN IT'S GOING TO HAPPEN, THAT CAN CATCH YOU OFF GUARD. I HAVE ALL THE OLD PARTS THAT I REPLACED. I CAN HAVE PICTURES AVAILABLE IF NEEDED. AND I STILL HAVE THE PROBLEM. *JB

I AM THE OWNER OF A YAMAHA R1 2004 MOTORCYCLE. AFTER 5000 MILES THE BIKE WILL DROP TO A LOW IDLE 500 RPM AND THEN SHUT DOWN. THIS IS VERY DANGEROUS, AND HAS CAUSED MANY CRASHES, AND INJURIES! I BELONG TO MANY FORUMS AND THIS IS HAPPENING ALL OVER THE WORLD TO 2004 YAMAHAS, IT IS THE LEFT TPS SENSOR! THIS NEEDS TO BE RECALLED BEFORE SOMEONE IS KILLED! JESSE ZIMMERMAN. *JB

(1) AROUND 5,000 MILES I NOTICED MY BIKE STARTED STALLING OUT AT 4,000 RPM OR LESS. (2) ENGINE WOULD IDLE REALLY LOW AND STALL OUT. BIKE WOULD USUALLY NOT START BACK UP RIGHT AWAY. LAST YEAR IN THE FALL I WAS IN A TURN AND MY BIKE STALLED OUT AND I LOSS CONTROL AND CRASHED. I INJURED MY RIGHT HAND, CHEST, RIGHT LEG AND HAD DAMAGE TO MY BIKE, CLOTHES AND HELMET. (3) I FOUND THAT I WASN'T THE ONLY PERSON HAVING THIS PROBLEM. THE DEALERSHIPS DENY HAVING A PROBLEM AND CLAIM I AM THE ONLY PERSON. THEY SAID THE CAN'T FIX SOMETHING IF THEY CAN'T DUPLICATE IT. THEY HAVE HAD 2 REVISIONS OF THE SUSPECT PART AND NOW MY WARRANTY IS EXPIRED SO IT WOULD COST ME OUT OF MY POCKET. I DID NOTICE LIKE OTHERS, THERE SEEMS TO BE A TEMPORARY FIX BY TURNING THE IGNITION KEY OFF THEN BACK ON. THERE HAS BEEN NOTHING DONE TO FIX MY BIKE. YAMAHA CUSTOMER SERVICE CLAIMS I AM THE ONLY PERSON WITH THIS ISSUE AND WON'T HELP!! THERE IS A WEBSITE DEVOTED TO THIS BIKE AND A TREND JUST FOR THIS ISSUE. BELOW IS THE LINK TO THE TREND WHERE YOU WILL SEE I AM NOT THE ONLY PERSON WITH THE SAME ISSUE AND YOU WILL READ ABOUT HOW OTHERS HAVE BEEN INJURED AS A RESULT OF THIS.

MY SON WAS RIDING A 2004 YAMAHA YZ250F MOTOCROSS MOTORCYCLE ON 1/7/05 WHEN ON HIS APPROACH TO A JUMP HIS MOTOR QUIT RUNNING. THE CARBURETOR POPPED OUT OF ITS MOUNTING [INTAKE BOOT]. THE CONSEQUENCE WAS THAT AS MY SON WAS COMMITTED TO CLEARING THE JUMP. THE YAMAHA LOST POWER, AND HE CRASHED INTO THE FACE OF THE LANDING HILL. AND BROKE HIS COLLARBONE ON IMPACT. AFTER I MADE SEVERAL INQUIRIES I WAS SURPRISED TO LEARN THAT THIS IS A COMMON PROBLEM WITH THIS MAKE AND MODEL OF MOTORCYCLE SINCE IT INTRODUCTION IN 2001. WHEN I CALLED YAMAHA CUSTOMER RELATIONS I WAS TOLD THAT THERE WASN'T A PROBLEM. MY SON BROKE HIS COLLAR BONE,,WHAT IF IT WAS HIS NECK OR WORSE.THERE SHOULD SEND A LETTER TO EVERYONE WHO BOUGHT A YAMAHA YZ250F AND SEE HOW MANY TIMES THIS HAS HAPPANED AND WHAT THE RESULTING INJURIES WERE. THANK YOU. *AK

WHILE RIDING AT 70 MPH MOTORCYCLE LOST CONSIDERABLE POWER AND STARTED TICKING LOUDLY. CONSUMER EXAMINED THE MOTORCYCLE BUT COULD FIND THE CAUSE OF THE PROBLEM. DEALER INSPECTED THE VEHICLE AND FOUND THAT THE ENGINE BLEW OUT. THEN, CONSUMER DISCOVERED THAT BEFORE THE MOTORCYCLE WAS BOUGHT MOTOR BLEW OUT ONCE, AND WAS REPLACED. *AK
