YAMAHA Complaints

I KNOW IN FACT I'M NOT THE FIRST TO MAKE A COMPLAINT REGARDING AN ISSUE THAT I HAVE ON MY 2007 YAMAHA YZF R1 MOTORCYCLE. THE FOLLOWING IS THE BEST DESCRIPTION I CAN GIVE FOR A THROTTLE LAG PROBLEM IN THE 2ND GEAR AT APPROXIMATELY 5000-5500 RPM. THE MOTORCYCLE WILL NOT RESPOND TO THE THROTTLE OPENING AND HESITATES FOR APPROX. 2 SECONDS BEFORE IT WILL ACCELERATE. I FOR ONE THINK THIS IS VERY DANGEROUS ESPECIALLY DURING INTERSTATE RIDING WHEN THE NEED TO ACCELERATE RAPIDLY EXISTS. AT THIS POINT YAMAHA HASN'T RESPONDED TO THE PROBLEM AND I AM A MEMBER OF R1 FORUM.COM AND THE MAJORITY OF OWNERS OF THE 2007 MODEL HAS EXPERIENCED. I AM HOPING THAT NHTSA CAN HELP WITH THIS PROBLEM THAT YAMAHA REFUSES TO CORRECT AND HOPEFULLY GET A RECALL ISSUED. ANY HELP WITH THIS MATTER WOULD TRULY BE APPRECIATED. *JB

GAS SEEMS TO BOIL OUT OF THE CARBURETOR AFTER SHUTTING OFF THE MOTORCYCLE WHEN HOT AND OVERFLOWS ONTO THE HOT ENGINE CASE AND EXHAUST. THIS HAPPENS QUITE OFTEN WHEN SHUTTING OFF THE ENGINE WHEN IT IS HOT. VERY SCARY. *AK

TL*THE CONTACT OWNS A 2007 YAMAHA YZFR1. WHILE ATTEMPTING TO ACCELERATE FROM 47 TO 55 MPH THE VEHICLE HESITATED FOR THREE TO FIVE SECONDS. THE FAILURE HAS BEEN OCCURRING SINCE THE VEHICLE WAS PURCHASED FOURTEEN DAYS AGO. THE CONTACT FILED A COMPLAINT ON TWO OCCASIONS WITH THE DEALER AND THE MANUFACTURER, HOWEVER, BOTH HAVE STATED THAT THE VEHICLE WAS OPERATING NORMALLY. THE CURRENT MILEAGE WAS 636, AND FAILURE MILEAGE WAS 50.*AK THE CONSUMER PROVIDED INFORMATION ON OTHER COMPLAINTS PERTAINING TO THE SAME PROBLEM. UPDATED 05/04/07*TR

THERE IS A THROTTLE LAG ON MY 2007 YAMAHA R1 FOR ABOUT 3 SECONDS AT SECOND GEAR 5500 RPMS. *AK

I WAS RIDING ON THE FREEWAY ON ROUTE 1. I TRIED TO PASS A CAR IN TRAFFIC IN 2ND GEAR AT 5500 RPM NO THROTTLE RESPONSE FOR APPROXIMATELY 4 SECONDS. THIS BIKE DID NOT ACCELERATE FROM 5500 RPMS IN 2ND GEAR PROPERLY. HAVING NO THROTTLE RESPONSE IN 2ND GEAR AT 5500 COULD HAVE COST ME MY LIFE. YAMAHA SAID THERE WAS NOTHING WRONG WITH THE BIKE. PLEASE HELP BEFORE SOMEONE GOT HURT .*AK

2007 YAMAHA R1, THROTTLE LAGGED AT AROUND 5500 RPMS. NO RESPONSE FOR A FEW SECONDS. CAN CAUSE SERIOUS PROBLEMS WHEN NEED TO SPEED UP OR TAKE OFF BEFORE BEING RAN OVER A SUV OR IN AN INTERSECTION OR OVERTAKING ANOTHER VEHICLE. FOOT PEG BRACKET BROKEN. WAS PARKING THE BIKE WHEN I PUT SOME PRESSURE ON THE FOOT PEG, IT BROKE AND MYSELF AND THE BIKE WENT DOWN. NO INJURIES, JUST DAMAGES WHICH I WANT TO BE REIMBURSED BY YAMAHA.... BUT IT COULD BE FATAL IN CASE OF RIDING IN TRAFFIC. I REALLY THOUGHT SOMEHOW I SCREWED UP, AND REASON WHY I WENT DOWN, UNTIL I FOUND OUT THAT MANY MORE PEOPLE WERE HAVING THE SAME PROBLEM. NOW I HAVE NO DOUBT THAT MY BIKE AND I WENT DOWN BECAUSE OF A STRUCTURAL PROBLEM WITH THE MATERIAL USED IN THE FOOT PEG. I HAVE PICTURES AVAILABLE.... PLUS ORDERED A NEW FOOT PEG, AND IT IS ON BACK ORDER.! MAYBE YAMAHA TOOK THEM ALL OFF THE MARKET , AND IS REPLACING THEM WITH NEW ONES? OR MAYBE IT MEANT MANY PEOPLE WERE HAVING TO BUY NEW ONES. WHEN IS THIS GOING TO BE TAKEN SERIOUSLY AND ACTIONS TAKEN?*AK

THE 2007 YAMAHA R1 MOTORCYCLE WITH FLY-BY-WIRE THROTTLE HAS A DEFINITE LAG OF THROTTLE. THIS SEEMS TO HAPPEN A LOT AT 5,500 RPMS WHILE IN 2ND GEAR. WHEN IT OCCURS THERE IS AT LEAST A 6-8 SECOND LAG IN THE THROTTLE. IT FEELS LIKE THE ENGINE SHUT OFF , THEN IT VERY SLOWLY COMES BACK TO LIFE. I FEEL THIS PROBLEM EVERY TIME I RIDE THE MOTORCYCLE AND CAN REPRODUCE IT AT WILL. THIS ALMOST CAUSED ME TO GET IN AN ACCIDENT BEING REAR-ENDED. I HAVE CONTACTED THE LOCAL DEALER, WHO SAID IT WASN'T AN ISSUE , AND ALSO YAMAHA WHO TOLD ME THAT THIS WAS THE WAY IT WAS SUPPOSED TO BE. TO ME THIS SEEMS TO BE A SAFETY ISSUE BECAUSE WHEN IT HAPPENS THE MOTORCYCLE WILL NOT ACCELERATE. I A WONDER IF THERE IS A GLITCH WITH THE THROTTLE-BY-WIRE SYSTEM WHERE THERE ISN'T ANY THROTTLE... CAN A PROBLEM OCCUR WHERE THE THROTTLE WILL GO WIDE-OPEN FOR A FEW SECONDS. THIS SEEMS LIKE A DANGEROUS ISSUE TO ME. *AK

I AM EXPERIENCING THROTTLE LAG ON MY 2007 YAMAHA YZF R-1 MOTORCYCLE. WHEN I AM IN 2ND GEAR AND AT 48 MPH WHEN I TWIST THE THROTTLE THERE IS A DELAY IN POWER DELIVERY, AND THEN ALL OF A SUDDEN IT TAKES OFF. IT ONLY HAPPENS IN THAT SITUATION. IT WORKS FINE IN ANY OTHER. *AK

2007 YAMAHA YZF-R1 HAS AN ACCELERATION LAG IN SECOND GEAR WHEN TRYING TO ACCELERATE FROM 5,500 RPM. ACCELERATION FROM LESS RPM, OR MORE THE LAG IS NOT PRESENT, BUT IT IS ALWAYS PRESENT IN SECOND GEAR AT 5,500 RPM. WHEN THIS LAG OCCURS IT IS PRESENT FOR SEVERAL SECONDS BEFORE THE BIKE WILL ACCELERATE. WHEN IT DOES START TO ACCELERATE, IT IS A SLOW SOFT ACCELERATION REGARDLESS OF THROTTLE INPUT. IT SEEMS TO ME THAT IN THIS CASE YOU DO NOT HAVE FULL CONTROL OVER THE MOTORCYCLE, WHICH IS VERY DANGEROUS AND LIFE THREATENING TO THE RIDER AND TO THOSE AROUND (PEDESTRIANS, CARS). AT THIS TIME I HAVE NOT NOTICED ANY OTHER FAULTS IN THE DRIVE BY WIRE THROTTLE, BUT THIS PROBLEM IS SCARY. WHAT IS TO SAY THAT THE THROTTLE WILL STAY OPEN WHEN YOU DO NOT INTEND? THIS IS AN ISSUE THAT NEEDS TO BE ADDRESSED IMMEDIATELY. MOTORCYCLE WAS PURCHASE NEW ON 3/3/07 AND THIS ISSUE WAS DISCOVERED ON 3/4/07 WITH 62 MILES ON THE BIKE AT FIRST OCCURRENCE. AS OF 4/4/07 BIKE HAS 669 MILES AND THIS ISSUE IS STILL PRESENT. IT WILL HESITATE ON EVERY ATTEMPT. DEALER IS AWARE AND WILL INSPECT ON THE BIKES FIRST SERVICE IN ONE WEEK. *JB

WHEN RIDING IN SECOND GEAR AT APPROXIMATELY 5500 RPM, AND HITTING THE THROTTLE YOU GET NOTHING, NO ACCELERATION FOR A GOOD 2 SECONDS. HAD HEARD ABOUT OTHERS HAVING THIS PROBLEM BUT I HADN'T EXPERIENCED IT UNTIL TODAY. NOTHING WAS DONE TO CORRECT THE FAILURE. AS A MATTER OF FACT , UPON FURTHER READING, YAMAHA HAS DOWNRIGHT IGNORED THIS PROBLEM AND THEIR CUSTOMER BASE BY NOT FIXING IT OUTRIGHT ON EVERY BIKE AFFLICTED BY THIS PROBLEM. *JB
