YAMAHA Complaints

2007 YAMAHA R1- THE OTHER DAY I WAS IN RUSH HOUR TRAFFIC ON MY MOTORCYCLE. I WAS DRIVING AT APPROXIMATELY 45 MPH IN SECOND GEAR WHEN THE CAR NEXT TO ME BEGAN TO MERGE OVER ON ME. I TRIED TO ACCELERATE TO AVOID A COLLISIONS BUT MY BIKE DID NOT IMMEDIATELY RESPOND TO THE THROTTLE. FORTUNATELY I WAS ABLE TO MANEUVER OUT OF THE WAS OF THE MERGING VEHICLE.. THE LAG IN THE THROTTLE RESPONSE SEEMED VERY STRANGE TO ME SO I DECIDED TO TEST THE BIKE BY RECREATING THE SCENARIO. MY FINDING WERE, IF I RIDE THE MOTORCYCLE IN 2ND GEAR AT APPROXIMATELY 48 MPH (5500 RPM) AND TRY TO QUICKLY ACCELERATE (IE- TO AVOID A COLLISION,,,ETC), THE BIKE WILL LAG AND ACCELERATE SLOWLY. THIS DEFECT WAS CONSISTENT EACH TIME I TESTED THE BIKE. ALL OTHER GEARS AND SPEEDS, ACCELERATION WAS PERFECT. BEFORE CONTACTING THE DEALERSHIP ABOUT MY PROBLEM, I DECIDED TO DO SOME RESEARCH ONLINE. I DID A GOOGLE SEARCH FOR 2007 YAMAHA R1 LAG, AND TO MY SURPRISE, I GOT COUNTLESS RESULTS ON THE TOPIC. APPARENTLY THE ISSUE IS FOUND IN ALL 2007 YAMAHA R1S IN THE U.S. NOW, BEING AN EXPERIENCED RIDER, I CAN SURLY SAY THAT 40 TO 50 MPH ARE VERY COMMON SPEEDS FOR A MOTORCYCLIST WHO TRAVELS CITY STREETS. AND ITS A FACT THAT ACCELERATION ALONG WITH PROPER BRAKING AND MANEUVER ABILITY, ARE KEY COMPONENTS TO RIDING A MOTORCYCLE AND AVOIDING LIFE THREATENING SITUATION WHILE IN TRAFFIC. THE YAMAHA WEBSITE CLEARLY STATES,,,THE YZF-R1 USES THE YCC-T FLY-BY-WIRE THROTTLE SYSTEM FOR FLAWLESS RESPONSE UNDER ALL CONDITIONS. YAMAHA CHIP CONTROL THROTTLE CONTROLS A 32-BIT ECU FUEL INJECTION SYSTEM FOR SUPER-RESPONSIVE, SMOOTH, INSTANTANEOUS POWER DELIVERY. THIS IS FAR FROM TRUTH AND YAMAHA NEEDS TO ADDRESS THIS ISSUE. *JB

I WAS RIDING MY MOTORCYCLE ON THE HIGHWAY WHILE I CAME UP BEHIND A CAR IN THE RIGHT LANE. THE SPEED LIMIT IS 65 MPH AND THE CAR WAS DOING 50 MPH IN 2ND GEAR. I DECIDED TO PASS THE CAR IN THE LEFT LANE. I SIGNALED TO GET INTO THE LEFT LANE CHECKED MY MIRRORS AND STARTED TO MOVE OVER AND AT THE SAME TIME ACCELERATE. FOR SOME REASON IT FELT LIKE THE MOTORCYCLE TURNED OFF. THERE WAS NO ACCELERATION FOR ABOUT 2 SECONDS. I WAS LUCKY THAT THERE WAS NO CARS IN THE LEFT LANE. AFTER ABOUT 2 SECONDS THE BIKE ACCELERATED AS NORMAL. I LOOKED UP THE INFORMATION ONLINE ABOUT THIS ISSUE AND I FOUND OUT THIS PROBLEM IS COMMON FOR ALL THE 2007 YAMAHA R1'S IN THE USA. I HAVE ALREADY DUPLICATED THIS PROBLEM OVER 10 TIMES IN SECOND GEAR AT 5500 RPM'S. *JB

2007 YAMAHA 1600/1700 ROADSTAR MOTORCYCLE THE CARBURETOR IS PUSHING OUT GAS ONTO THE ENGINE BLOCK WHEN YOU SHUT IT OFF GAS SPILLS OUT ONTO ENGINE CURRENTLY WORKING WITH DEALER TO FIND THE PROBLEM. *JB

2000 YAMAHA XV1600 ROADSTAR MOTORCYCLE HAS BEEN "PUKING" GASOLINE FROM THE CARB AFTER SHUTTING DOWN THE ENGINE (HOT.) IT DOES THIS ALMOST EVERY TIME AFTER RIDING THE BIKE. THERE HAVE BEEN NO FIRES, OR INJURIES THUS FAR, BUT I'M SURE IT'S JUST A MATTER OF TIME BEFORE SOMETHING GOES WRONG. YAMAHA MOTOR OF AMERICA, AND LOCAL DEALER SERVICE DEPARTMENT DO NOT ACKNOWLEDGE THE ISSUE. *JB

I WAS RIDING MY MOTORCYCLE OUT OF ASPEN COLORADO WHEN I STOPPED TO GET GAS. I FILLED THE TANK ON MY MOTORCYCLE. I THEN WENT INSIDE AND TOOK A 15 MIN BREAK. I THEN GOT BACK ON MY BIKE, STARTED IT AND TOLD MY WIFE TO GET ON. AS SHE WAS GETTING ON THE BIKE STALLED. UNKNOWN TO ME THE CARBURETOR STARTED OVERFLOWING, DUMPING FUEL ON THE HOT PIPES AND MY RIGHT BOOT. I HIT THE STARTER TO RESTART THE BIKE AND THE BIKE BACKFIRED SETTING THE VAPORIZED FUEL ON FIRE. WE WERE ABLE TO PUT THE FIRE OUT. THERE WAS SOME DAMAGE TO THE BIKE AND THE BIKE HAD TO BE TRAILERED BACK TO OHIO. THANKFULLY NO ONE WAS INJURED. *JB

CARBURETOR ON 2003 YAMAHA ROADSTAR (XV1600) WILL SPIT GAS OUT ON HOT CYLINDER HEADS AND CRANKCASE UNPREDICTABLY. HAPPENS WHEN RESTARTING ENGINE AFTER ENGINE HAS BEEN STOPPED FOR A SHORT PERIOD AFTER COMING IN FROM A RIDE. RIDE CAN BE SHORT OR LONG; UNPREDICTABLE. WAS CHECKED BY DEALER DURING FIRST FEW MONTHS WHEN NEW AND CARB NEEDLE WAS REPLACED. PROBLEM HAS PERSISTED AND OCCURS EVERY FEW MONTHS THEREAFTER AND IS ONLY RESOLVED BY TURNING OFF FUEL VALVE BEFORE STOPPING SO CARB EMPTIES. NUMEROUS OTHER RIDERS HAVE SEEN SAME PROBLEM. LAST EVENT FOR ME SHOWN BELOW IN INCIDENT DATE. *JB

2007 YAMAHA YZF R1. WHILE IN SECOND GEAR AND AT 5500 RPMS THE MOTORCYCLE DOES NOT PERFORM AS EXPECTED WHEN THROTTLE IS APPLIED. THE MOTORCYCLE HAS A LAG IN ACCELERATION THAT UPSETS OR CAUSES AN UNSAFE SHIFT IN UNPREDICTABLE WEIGHT WHILE IN A TURN. THIS IS OF GRAVE CONCERN FOR MY SAFETY AS THIS UNPREDICTABLE CHARACTERISTIC HAS PLACE ME IN CLOSE CALL ACCIDENTS SEVERAL TIMES. *JB

I HAVE RECENTLY PURCHASED THE 2007 YAMAHA YZFR1 AND HAVE SOME CONCERNS REGARDING THE SAFETY OF THIS VEHICLE. FIRST OFF I WOULD LIKE TO REPORT THE ISSUE OF A FLAT SPOT IN ACCELERATION. WHEN THE VEHICLE IS AT APPROXIMATELY 5500 RPM AND THROTTLE IS APPLIED THERE IS A DELAY IN ACCELERATION LASTING BETWEEN 3-5 SECONDS. THIS DELAY COULD CAUSE INJURY OR POSSIBLE DEATH DUE TO ACCIDENTS OCCURRING WHEN ACCELERATION IN THIS RANGE IS NECESSARY. THE SECOND ISSUE IS WITH THE REAR SET (FOOT PEGS). ALTHOUGH THIS HAS NOT OCCURRED ON MY VEHICLE, THERE HAVE BEEN CASES OF THE SET CRACKING AND BREAKING. IF THIS WERE TO HAPPEN WHILE THE VEHICLE WAS IN MOTION IT CAN CAUSE INJURY OR POSSIBLE DEATH. *JB

I HAVE A 2005 YAMAHA ROADSTAR 1700 MOTORCYCLE. WHEN THE MOTORCYCLE IS RESTARTED, AFTER IT IS HOT,GAS OVERFLOWS FROM THE CARBURETOR ALL OVER THE ENGINE AND EXHAUST. THIS HAPPENED 3 TIMES , AND IT HAPPENED TO TWO FRIENDS WITH THE SAME MOTORCYCLE. I CALLED THE DEALER , AND THEY SAID THAT THEY WERE CONTACTING YAMAHA TO FIND OUT WHAT TO DO BECAUSE THEY HAD SEVERAL CALLS ABOUT THE SAME THING HAPPENING TO OTHERS. YAMAHA CLAIMED IT WAS CAUSED BY WINTER GAS. THEY SAID THE PROBLEM WILL GO AWAY IN A FEW WEEKS WHEN THE GAS COMPANIES CHANGE TO THEIR SUMMER FORMULA. AT LEAST 1 OUNCE OF GAS IS SHOT ONTO A HOT ENGINE AND EXHAUST. THIS IS A MAJOR FIRE HAZARD. *AK

WHILE DRIVING IN RUSH HOUR TRAFFIC I OBSERVED A CAR BEHIND ME WAS APPROACHING FAST. I ROLLED ON THE THROTTLE TO ACCELERATE , AND NOTHING HAPPENED FOR ABOUT THREE SECONDS. THEN BIKE BEGAN TO SLOWLY ACCELERATE AND I WAS ALMOST REAR ENDED BECAUSE OF THIS DEFECT. WELL, I WAS ALMOST REAR ENDED BECAUSE THE DRIVER BEHIND ME WAS NOT PAYING ATTENTION. BUT THE BIKE'S DEFECT COULD HAVE KILLED ME. YAMAHA CONTINUED TO IGNORE THIS DEFECT BY SAYING THAT THEY HAVE NOT HEARD OF THIS BEFORE. THIS WAS A LIE, AND COULD BE PROVEN. YAMAHA KNEW OF THIS DEFECT AND CHOSE TO COMPLETELY IGNORE IT. NOT ENOUGH DEATHS YET? *AK
