YAMAHA Complaints

THIS MOTORCYCLE CONSISTENTLY REFUSES TO ACCELERATE WHEN IN SECOND GEAR AT APPROXIMATELY 550RPM OR 49 MPH. THERE IS A SUBSTANTIAL DELAY IN RESPONSE AND A VERY SLOW INCREASE IN SPEED UNTIL NEARLY 70 MPH IS REACHED WHEN IT STARTS TO ACCELERATE AS NORMAL. THERE ARE NO FAULT CODES OR ANY OTHER ABNORMAL INDICATIONS, AND THIS CAN BE RECREATED AT ANY TIME. THIS POSES A SIGNIFICANT HAZARD FOR COLLISION AVOIDANCE AS WELL AS MERGING WITH EXISTING TRAFFIC. *TR

2007 YAMAHA YZF-R1 SUPER SPORT MOTORCYCLE. THERE IS A CONSTANT FAILURE MODE IN THE ENGINE MAPPING THAT CAUSES SLOW ENGINE ACCELERATION IN THE FOLLOWING CONDITIONS: 2ND GEAR, 5500 RPMS.

AFTER CONTACTING YAMAHA, I WAS TOLD THAT THE ENGINEERS HAS EVALUATED THE CONDITION AS A CHARACTERISTIC OF THE MOTORCYCLE AND NOT A SAFETY ISSUE. YAMAHA HAS NO PLANS TO CORRECT THIS ISSUE.

I HAVE A 2001 YAMAHA ROAD STAR MIDNIGHT SILVERADO THAT HAS AN INTERMITTENT GAS LEAK PROBLEM. IT USUALLY ONLY HAPPENS WHEN THE ENGINE IS HOT BUT NOT ALWAYS. WHEN TRYING TO START THE BIKE GAS FLOWS OUT OF THE CARBURETOR DOWN THE ENGINE AND ON TO THE GROUND. MY FRIENDS 99 ROAD STAR DOES THE SAME AND I HAVE HEARD FROM SEVERAL OTHER OWNERS THAT HAVE THIS SAME PROBLEM. THE BIKE WILL NOT START AND ACTS LIKE IT IS FLOODED AS GAS POURS DOWN THE RIGHT SIDE OF THE HOT ENGINE. THE BIKE ONLY STARTS AFTER SITTING FOR 10 TO 20 MINUTES.*AK

TL* - THE CONTACT OWNS A 1999 YAMAHA ROADSTAR WITH A CURRENT AND FAILURE MILEAGE OF 75000 MILES. THE STEEL FRAME THAT THE MONO SHOCK BOLTS CRACKED. THE CONTACT STATED THAT WHEN RIDING LESS THAN 5 MPH AND HITTING A BUMP THE SHOCKS WOULD NOT RESPOND. HE TOOK THE MOTORCYCLE TO A DEALER, EASTERN MOTOR SPORTS SOUTH, AND WAS TOLD THAT HE NEEDED A NEW FRAME. THE MANUFACTURER SOLD THE CONTACT A NEW FRAME AT HALF PRICE. THE DEALER COULD NOT DETERMINE HOW THE STEEL FRAME FAILED. *AK

I PURCHASED MY MOTORCYCLE BRAND NEW AND NOTICED ONE DAY WHILE TRYING TO ACCELERATE IN SECOND GEAR AFTER SLOWING THAT THE BIKE DID NOT RESPOND. THE BIKE ACTED AS IF IN SLOW MOTION AND THEN ALL OF A SUDDEN THE POWER RETURNED TO IT. IT WILL CONTINUE TO DO IT TO THIS DAY AND I DO NOT KNOW WHY. I HAVE SINCE LEARNED IT IS A WIDESPREAD PROBLEM. I BELIEVE IT IS A VERY REAL SAFETY ISSUE DUE TO THE FACT THAT IT HAS HAPPENED ONCE WHEN I WAS TRYING TO GET OUT OF THE WAY OF A VEHICLE THAT WAS MOVING INTO MY LANE. LUCKILY THEY NOTICED ME AT THE LAST MINUTE BUT I CAN'T EXPECT THAT TO ALWAYS BE THE CASE. *JB
