2004 YAMAHA YZF-R1 Complaints

IN THE SUMMER OF 2005, WHILE RIDING MID-TURN, MY 2004 YAMAHA YZF-R1 LURCHED AND CUT-OUT CAUSING ME TO LOW SIDE MY MOTORCYCLE. I RECEIVED MINOR INJURIES AND MY MOTORCYCLE WAS WRECKED AND IS BRANDED SALVAGE ON THE TITLE. AFTER THE INCIDENT AND REPAIRING MY BIKE, APPROXIMATELY TWO WEEKS LATER IT DID THE SAME THING IN TRAFFIC. THE BIKE WILL RUN VERY ROUGH, THE RPM'S WILL DROP, AND THEN THE BIKE WILL CUT-OUT. LOOKING ON THE INTERNET, I HAVE FOUND THAT I AM NOT THE ONLY ONE WITH THIS PROBLEM, BUT ONE OF MANY. THIS PROBLEM STARTS TO OCCUR AROUND THE 5000 MILE MARK ON THE BIKE. THEIR ARE MANY ANSWERS TO THE PROBLEM, BUT NOT TRUE SOLUTIONS. I ONLY WISH THAT THE PROBLEM HAD NOT ARISEN MID-TURN COSTING ME SO DEARLY. THIS IS DEFINITELY A SAFETY ISSUE AS I AM NOT THE ONLY ONE WHO HAS CRASHED AND WHO KNOWS WHAT LIVES HAVE BEEN TAKEN DUE THIS MALFUNCTION. ONE SOLUTION RECOMMENDED IS THE REPLACEMENT OF THE TPS VALVES. I HAVE YET TO DO THIS SINCE I AM CURRENTLY IN IRAQ, BUT WILL AS SOON AS I RETURN TO THE STATES. THERE IS A WEBSITE DEVOTED TO THIS BIKE AND A VERY EXTENSIVE BLOG ON THIS ISSUE ALONE. THE LINK IS (HTTP://WWW.R1-FORUM.COM/FORUMS/SHOWTHREAD.PHP?S=A1D00CA84E6AB575C634E815B9AC2688&THREADID=98831&PERPAGE=20&PAGENUMBER=66) AND HAS OVER 66 PAGES OF INFORMATION AND COMPLAINTS DUE THIS PROBLEM. *JB

MY 2004 YAMAHA R1 CUTS OUT/STOPS RUNNING UNDER NORMAL RIDING CONDITIONS WITH NO WARNING, OR APPARENT FAILURE. I GET NO FAILURE CODES, OR WARNING LIGHTS PRIOR TO THIS HAPPENING. IT HAS HAPPENED TWICE AND IS EXTREMELY DANGEROUS WHEN RIDING IN TRAFFIC, OR ON TURN. YAMAHA IS AWARE OF FAULTY TPS SENSORS, BUT REFUSES TO ISSUE A RECALL AND/OR A SAFETY BULLETIN TO CORRECT THE PROBLEM. MANY OWNERS OF THIS BIKE HAVE ISSUED THE SAME COMPLAINT WITH NO ACTION TO DATE. *JB

I WAS GOING TO WATCH THE GAME IN PASADENA LAST NIGHT DOING ABOUT 75 MPH ON THE FASTLANE OF THE 134 FWY. ALL OF A SUDDEN I LOSE ALL POWER,(IT WAS LIKE SOMEONE HIT MY CUT OFF SWITCH ON MY RIGHT HANDLE BAR) LUCKY FOR ME I WAS ABLE TO MAKE IT ALL THE WAY TO THE RIGHT SHOULDER, SCARY. I TURNED THE KEY OFF, THEN ON AND RESTARTED, NO PROBLEM. IM HEARING FROM A LOT OF PEOPLE THAT IT IS THE TPS SENSORS: HTTP://WWW.R1-FORUM.COM/FORUMS/SHOWTHREAD.PHP?S=&THREADID=98831&PERPAGE=20&PAGENUMBER=1 HTTP://WWW.RONAYERS.COM/FICHE/501_2451/INTAKE_2/INTAKE_2.CFM?MAN=YA&GROUPID=32040&PARENT=31910. *NM

THIS FALL MY 2004 YZF R1(YAMAHA MOTORCYCLE) CUT OUR TWICE AT 60 MPH. I WAS LUCKY IN THE FACT THAT I WAS JUST GOING STRAIGHT ON THE HIGHWAY. IF I HAD BEEN GOING ON A TIGHT CURVE THE OUT COME WOULD HAVE BEEN DIFFERENT. WHEN THE ENGINE CUTS OUT IT'S LIKE SLAMMING ON THE REAR BRAKE OR "ENGINE BRAKING", AND ON A CORNER THIS WOULD MAKE YOU WIPE OUT. TALKED TO THE YAMAHA DEALERSHIP IN TOWN BUT THEY HAD NEVER HEARD OF THIS PROBLEM BUT I KNOW OF OTHER PEOPLE THAT HAVE HAD THIS PROBLEM. THIS IS DANGEROUS AND NEEDS TO BE ADDRESSED. I BOUGHT THE BIKE NEW IN MARCH 2004 AND NOW HAS 7900 MILES ON IT. *JB

I OWN A 2005 YAMAHA YZF-R1, AFTER 2500 MILES THE MOTOR WILL INTERMITTENTLY DROP TO AROUND 500RPM OR LOWER WHEN IDLING OR WHEN CLUTCH LEVER IS PULLED IN. WHEN THIS HAPPENS THE MOTOR WILL DROP INTO A LUMPING AND THEN CUT OUT. IT ALSO OCCURS WHILE MOTORCYCLE IS IN MOTION. THE MOTOR WILL JERK AND LURCH WHEN YOU ENGAGE THE CLUTCH IT DIES. THIS HAS HAPPENED SEVERAL TIMES AND IS A REAL HAZARD. WHEN MOTORCYCLE IS IN DIAGNOSTIC MODE IT DETECTS A FAULT CODE FOR THE (TPS) THROTTLE POSITION SENSOR AND HAS BEEN DOCUMENTED ON HUNDREDS OF R1'S WORLDWIDE. HERE IS A LINK TO THE FORUM WHERE IT IS BEING DISCUSSED. HTTP://WWW.R1-FORUM.COM/FORUMS/SHOWTHREAD.PHP?S=&THREADID=98831&PERPAGE=20&PAGENUMBER=1. *JB

WAS DRIVING MY YAMAHA R1 AND WENT TO MAKE A LEFT TURN,TRIED TO STRAIGHTEN OUT AND FRONT END WOULD NOT TURN,CRASHED DOING APPROX 15 MILES AN HOUR BIKE FLIPPED ON ME AND I WAS INJURED. BOLT THAT HELD THE FRONT STABILIZER CAME OUT CAUSED THE STABILIZER TO JAM WHEN TRYING TO TURN RIGHT, UPON INVESTIGATION BY A MECHANIC WAS TOLD THAT WAS A BAD DESIGN AND NO LOCTITE ON THE THREADS, POTENTIAL FOR DISASTER, WAS A MATTER OF TIME,DUE TO THIS HAVE SEVERE PAIN IN BACK AND 1 LEG THAT IS NON STOP,THIS COULD HAVE BEEN A MORE SERIOUS SITUATION AS IN DEATH IF HAVE FALLEN IN FRONT OF A CAR. *NM

I OWN A 2004 YAMAHA YZF-R1 (PURCHASED NEW). ABOUT THE BEGINNING OF MAY OF 2005 THE MOTORCYLE WOULD STALL ON ME WHEN THE BIKE WASN'T MOVING OR WHENEVER THE CLUTCH IS PULLED IN. BASICALLY THE BIKE'S IDLE WOULD DROP TO ABOUT 500 RPM, THE BIKE WOULD RUN REALLY ROUGH, AND IT WOULD STALL WHENEVER THE CLUTCH WAS PULLED IN OR WHEN THE SPEED WAS DECREASED TO BELOW 5 MPH. I HAVE ALSO NOTICED THAT WHEN THE PROBLEM IS STARTING TO OCCUR THAT THE BIKE WOULD BUCK AND THERE WOULD FEEL LIKE THERE WASN'T ANY ENGINE BRAKING. I KNOW THAT I AM NOT THE ONLY ONE WITH THIS PROBLEM. THIS IS HAPPENING TO ALL YAMAHA RIDERS ACROSS THE WORLD AND CAN BE FOUND ON MY YAMAHA FORUM SITES. THIS PROBLEM NEEDS TO BE FIXED BEFORE OTHER CRASH RESULTING IN INJURY OR DEATH. *NM

DEAR NHTSA: I AM WRITING THIS COMPLAINT IN REGARDS TO THE CONTINUOUS ENGINE FAILURE OF A YAMAHA MOTORCYCLE. SEVERAL WEEKS AGO, THE ENGINE STARTED HESITATING DURING A REGULAR RIDE AND WHEN THE THROTTLE WAS RELEASED IT WOULD NOT IDLE BUT STOP; THE ENGINE QUITS RUNNING EVEN WHEN SHIFTING GEARS, WHICH COULD LEAD TO A SERIOUS INJURY EVEN DEATH IF HAPPENS ON A CURVE. I TOOK THE VEHICLE TO A MECHANIC AND AFTER SEVERAL WEEKS OF TROUBLE SHOOTING AND DIAGNOSIS I WAS TOLD THAT THEY DIDN'T FIND WHAT WAS WRONG! THEN I SEARCHED THE INTERNET AND BECOME AWARE THAT THIS WAS A COMMON PROBLEM, SOMEONE EVEN REPORTED AN INJURY, CAUSED BY A FAULTY THROTTLE POSITION SENSOR (TPS), AT LEAST THE END USERS HAVE SUGGESTED THAT WAS THE CULPRIT WHILE YAMAMA MOTORS IGNORED THE CONCERNS OF THE RIDERS. I AM SURPRISED THAT YAMAHA HAS NOT TAKEN THIS MATTER SERIOUSLY AND HAS NOT MADE A RECALL OR ISSUED A TECHNICAL BULLETIN. THIS IS MIND BATTLING TO ME SINCE IT CAN LEAD TO SERIOUS ACCIDENTS AND EVEN FATALITIES. NEVERTHELESS, I BELIEVE THAT THE NHTSA WILL TAKE THE MATTER SERIOUSLY IN AN EFFORT TO KEEP THE ROADS SAFER, AND FORCE THE MANUFACTURERS TO ACT PROMPTLY AND RESPONSIBLY. THE MORE OF THESE STORIES CAN BE READ ON THE VARIOUS FORUMS INCLUDING THE FOLLOWING SITE (HTTP://R1-FORUM.COM/FORUMS/SHOWTHREAD.PHP?S=&THREADID=98831&PERPAGE=20&PAGENUMBER=1) I WILL BE HAPPY TO ANSWER ANY QUESTIONS OR HELP WITH THE MATTER IN ANY WAY I CAN. BEST REGARDS, PLEASE MAKE THE ROADS SAFER.. FATIH BUYUKSONMEZ. *JB

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
