YAMAHA Complaints

THIS COMPLAINT IS IN REGARDS TO THE 2004 YAMAHA FZ6 THROTTLE POSITION SENSOR. AFTER THE MOTORCYCLE WARMS UP (APPROXIMATELY 50 MILES OF RIDING), IT WILL STALL OUT AND/OR SPUTTER WHEN THE CLUTCH IS ENGAGED AND/OR SHIFTED INTO NEUTRAL. LAST JULY IT STALLED OUT IN THE MIDDLE OF A RIGHT HAND TURN AROUND A RED LIGHT, RESULTING IN THE BACK TIRE LOOSING TRACTION AND CAUSING A CRASH. I WAS MINIMALLY INJURED, BUT THE BIKE SUFFERED SOME EXTERIOR DAMAGE. AFTER SOME RESEARCH I HAVE FOUND THAT THERE IS A PROBLEM WITH THE THROTTLE POSITION SENSOR. THIS PART WAS FIXED UNDER WARRANTY, BUT SEEMS TO BE AN ISSUE WITH MOST OWNERS OF THE 2004-05 FZ6.*JB

DT*: THE CONTACT STATED WHILE DRIVING AT VARIOUS SPEEDS EXTREME HEAT IS FELT FROM THE EXHAUST PIPE DUE TO THE LACK OF A HEAT SHIELD ON THE LEFT SIDE. THE VEHICLE WAS NOT INSPECTED. THE MOTORCYCLE IS A 2005 YAMAHA R1. *AK UPDATED 04/11/06. *JB

I HAVE A 2001 YZFR6 AND THE 2ND GEAR IS GOING OUT FOR THE SECOND TIME. I DON'T STUNT RIDE OR ABUSE MY BIKE. I BOUGHT THE BIKE BRAND NEW BACK IN '01 AND IN 01 OR 02 I HAD TO REPLACE THE SHIFTING FORKS FOR 2ND AND 6TH GEAR, ALSO THE GEARS THEMSELVES HAD TO BE REPLACED, 1500 DOLLARS. YAMAHA SAID THIS WAS FROM RIDING ABUSE. SUMMER OF 05 *BIKE WAS PARKED FOR ALL OF 04, 2ND GEAR STARTED TO SLIP AGAIN. I'VE HEARD FROM OTHER SOURCES THAT ALL R6'S FROM 99-02 HAVE THIS PROBLEM AND IT'S BECAUSE OF A MILLING ERROR IN THE TRANSMISSION DRUM. SINCE THERE IS AN ERROR THE 2ND GEAR SHIFTING FORK CAN'T REST IN THE CORRECT SPOT. *NM

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

THE MOTORCYCLE HAD PROGRESSIVELY WORSE STALLING AT STOP-LIGHTS AND STOP SIGNS. AT TIMES THE MOTORCYCLE WOULD STUTTER AND STALL WHEN TRYING TO INITIATE THE THROTTLE FROM A STOP, AND AT OTHER TIMES THE MOTORCYCLE WOULD RANDOMLY INCREASE SPEED WHILE CRUISING ON THE HIGHWAY. THE THROTTLE BECAME QUITE VARIOUS TO THE POINT IT WAS NOT SAFE TO RIDE IN TRAFFIC DUE TO NOT KNOWING HOW THE MOTORCYCLE WOULD REACT TO DIFFERENT THROTTLE INPUTS. IN ORDER TO FIX THE PROBLEM THE THROTTLE POSITION SENSOR HAD TO BE REPLACED. *NM

2000 YAMAHA V-STAR 650 CLASSIC; ONLY 8,000 ODOMETER MILES. NOTICED SEVERAL CRACKS OR FRACTURES IN THE REAR WHEEL HUB, WHICH WOULD CAUSE THE REAR HUB'S TO EVENTUALLY BREAK-UP AND POTENTIALLY SERIOUS INJURY AND/OR DEATH DUE TO REAR WHEEL LOCKUP AND HANDLING DIFFICULTIES. *JB

MOTORCYCLE'S IDLE RPMS CHANGE ABRUPTLY, TO THE POINT OF STALLING WHEN AT SLOW SPEEDS. THIS ABRUPT CHANGE WAS THE SOURCE OF A REAR END COLLISION. THE BIKE HAD BEEN TAKEN IN PREVIOUSLY TO THE DEALERSHIP ON MULTIPLE OCCASIONS BUT NO CORRECTIVE MEASURES WHERE TAKEN, AS THE PROBLEM COULD NOT BE REPRODUCED. THE SYMPTOMS CORRELATE WITH THOSE OF OTHER FZ6 USERS AND HAS BEEN LINKED TO A FAULTY TPS. *NM

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

THE FORWARD HORN BRACKET ON MY 2003 YAMAHA ROAD STAR HAS REGULARLY BROKEN AT 5000 MILE INTERVALS. I TOOK ONE AND BEEFED IT UP WITH WELDED-IN ROD AND ANGLED BRACKETS BUT IT STILL ONLY LASTED 15000 MILES. MY DEALER SAYS THEY HAVE REPORTED THIS PROBLEM TO YAMAHA, BUT WHEN I CALL THE CUSTOMER SERVICE LINE, THEY CLAIM TO HAVE NO KNOWLEDGE OF THIS PROBLEM. I ALSO INSTALLED AN EXTERNAL OIL COOLER ON THE BIKE AND HAD THAT BRACKET BREAK (I FEEL DUE TO THE EXTREME VIBRATIONS INHERENT IN THE BIKE)! NOW, ON THE NEW ROADLINER, THEY HAVE ADDRESSED THESE PROBLEMS, BUT WITHOUT CONFIRMING THAT THEY EXIST. *JB
