2007 Yamaha FJR1300

RIDING UP HILL SEVERE LOSS OF POWER AND POWER SURGES. SEVERAL TIMES ALWAYS RIDING UPHILL I HAVE HAD SEVERE POWER LOSSES AND POWER SURGES. CAUSED ME TO MISS TURN AND SLOW DOWN TO A STOP. I SHUT DOWN BIKE AND RESTARTED. TURNED AROUND AND WENT DOWNHILL AND THE BIKE OPERATED FINE. HAVE NOT HAD ANY REPAIRS OR MODIFICATIONS TO BIKE. THIS OCCURRED ON THE FIRST RIDE ON THIS BIKE UPHILL AND SEVERAL TIMES AFTER. HAVE ONLY RIDDEN 600 MILES ON THIS BIKE. *TR

1. WHILE RIDING MY NEW 2007 YAMAHA FJR1300 MOTORCYCLE THROUGH MOUNTAINOUS AREAS AND GAINING ALTITUDE FROM 1000-3000 FEET, THE THROTTLE CONTROL BEGINS SURGING AND ON/OFF THROTTLE ADJUSTMENTS BECOME VERY ABRUPT. 2. THE CONSEQUENCES OF THIS THROTTLE CONTROL PROBLEM ARE THAT THE MOTORCYCLE BECOMES VERY DIFFICULT TO CONTROL AND UNSAFE TO RIDE. 3. TURNING THE MOTORCYCLE OFF AND BACK ON WILL TEMPORARILY CORRECT THE PROBLEM UNTIL GAINING MORE ALTITUDE, THEN THE PROBLEM RETURNS. NO REPAIRS HAVE YET BEEN PERFORMED, THE SEVERAL YAMAHA DEALER SERVICE DEPARTMENTS I CONTACTED WERE NOT FAMILIAR WITH THE PROBLEM.

2007 YAMAHA MOTORCYCLE. MOTORCYCLE SURGES WITH THROTTLE RESPONSE WHEN CHANGING ALTITUDE. THE OFF & ON THROTTLE RESPONSE IS SEVERE TO THE POINT OF DISTRIBUTING THE SUSPENSION WHILE IN A CURVE. WITH ALTITUDE CHANGE APPLYING THE THROTTLE RESULTS IN NO SPEED INCREASE FOR A PERIOD , AND THEN EXTREME THROTTLE RESPONSE. THE MOTORCYCLE IS VERY DIFFICULT TO DRIVE SAFELY WITH THIS CONDITION IN THE MOUNTAINS. THE DEALER ADJUSTED THE LEVEL FOR THE FUEL INJECTION SYSTEM ON TWO OCCASIONS WITH VERY LITTLE IMPROVEMENT. I HAVE CONTACTED YAMAHA CUSTOMER RELATIONS ON TWO OCCASIONS WITHOUT ANY RESPONSE OR SUGGESTIONS FOR IMPROVEMENT. THE MOTORCYCLE WAS PURCHASED NEW ON 3/17/07 FROM PERFORMANCE YAMAHA, SENECA, SC, 864-888-8123. PLEASE HELP BEFORE SOMEONE LOSES THEIR LIFE WITH THIS PROBLEM.*AK

PROBLEM OCCURS DURING, OR SHORTLY AFTER CHANGING ALTITUDE. USUALLY BEGINS WITH A SLIGHT SURGING AT STEADY THROTTLE. THIS PROGRESSES TO A NON-RESPONSIVE THROTTLE. OPEN IT SLIGHTLY AND NOTHING HAPPENS. OPEN IT FURTHER AND IT COMES ON WITH A JOLT. SOMETIMES BIKE LURCHES LIKE ITS RUNNING OUT OF GAS. VERY DANGEROUS ESPECIALLY AT LOW SPEEDS OR IN TRAFFIC. ON 7/2/3007 YAMAHA CUSTOMER RELATIONS SAID I WAS THE 1ST CALLER WITH THESE SYMPTOMS. *TR

ALTITUDE-RELATED STALLING AND SURGING. WHEN INCREASING ELEVATION BY APPROX 1500 FEET OR MORE, BIKE WILL STALL COMING OUT OF CORNERS OR AT LOW LOADS WHEN APPLYING THROTTLE BELOW 3500 RPMS. INCREASING THROTTLE OPENING DOES NOTHING FOR APPROX 2-3 SECONDS AND THEN MOTOR SUDDENLY SURGES. VERY DANGEROUS IN TRAFFIC OR SLICK PAVEMENT SITUATIONS. PROBLEM APPEARS TO GO AWAY WHEN MOTOR IS SHUT OFF AND TURNED BACK ON AGAIN. PROBLEM PROGRESSIVELY RETURNS WHEN ELEVATION INCREASES, BECOMING UNDRIVABLE UNTIL ANOTHER SHUT-OFF. TOOK BIKE TO DEALER WITH COMPLAINT. YAMAHA REP STATES OWNER MUST PAY $75.00/HR FOR TECH TO RIDE BIKE UNTIL PROBLEM IS REPLICATED, DESPITE NUMEROUS COMPLAINTS OF SIMILAR INSTANCES ON INTERNET USER GROUPS. NO RESOLUTION AS YET. *TR
