2007 Yamaha FJR1300

TL*THE CONTACT OWNS A 2007 YAMAHA FJR13. WHILE DRIVING UPHILL AT 35 MPH, THE VEHICLE ACCELERATED TO 45 MPH WITHOUT WARNING. THE CONTACT STATED THAT HE BACKED OFF THE THROTTLE AND DOWNSHIFTED THE VEHICLE, WHICH RESOLVED THE ISSUE. APPROXIMATELY TWO WEEKS LATER, THE FAILURE RECURRED. THE FAILURE ONLY OCCURS WHILE DRIVING UPHILL. THE DEALER WAS UNABLE TO DIAGNOSE THE CAUSE OF FAILURE. THE CURRENT MILEAGE IS 3,700 AND FAILURE MILEAGE WAS 300.

WHILE RIDING THROUGH CHANGING ELEVATIONS, THE FUEL SYSTEM MALFUNCTIONS WHILE APPLYING THROTTLE BELOW 4,000 RPM. ESPECIALLY PREVALENT WHEN LOAD APPLIED NEAR IDLE SPEED. WHILE TRYING TO PERFORM A LOW SPEED MANEUVER (PULLING IN TO A GRAVEL PARKING LOT), THE ENGINE ACTED AS IF IT WAS GOING TO STALL, THEN CAUGHT SUDDENLY, RESULTING IN A FALL. *TR

WHILE RIDING THROUGH CHANGING ELEVATIONS, THE MOTORCYCLE EXPERIENCES AN EVER-INCREASING DELAY OF THROTTLE RESPONSE AFTER ENGINE BRAKING. THE SUDDEN DELIVERY OF FUEL TO THE ENGINE CAUSES UNSAFE HANDLING CHARACTERISTICS. IT ACTS AS IF IT IS OUT OF GAS WHILE TRYING TO ACCELERATE BELOW 4000 RPMS, THEN GETS AN UNEXPECTED DELIVERY OF POWER. THIS HAPPENED VIRTUALLY EVERY TIME I TRIED TO PREPARE FOR A CORNERING MANEUVER. *TR

WHILE DRIVING THROUGH A MOUNTAIN PASS (3,00FT), THROTTLE CONTROL BECAME UNSTABLE WITH ENGINE HESITATING THEN SURGING. AFTER EXITING FREEWAY THE BIKE VIOLENTLY SLOWED/SPEEDED UP WHEN TRYING TO GET UP TO SPEED. THE FACT NO OTHER TRAFFIC WAS PRESENT PREVENTED AN ACCIDENT. AFTER SHUTTING THE BIKE OFF AND RESTARTING IT OPERATED NORMALLY UNTIL I DROVE BACK DOWN TO SEALEVEL WHERE THE PROBLEM BRIEFLY REPEATED. I HAVE SINCE LEARNED THAT THIS SAME PROBLEM IS HAPPENING TO OTHER OWNERS AND THERE HAVE BEEN NO WARNINGS FROM THE DEALER OR MANUFACTURER. I WILL TAKE THE BIKE IN FOR SERVICE WHEN THEY OPEN THIS WEEK BUT REPORTS FROM OTHER OWNERS INDICATE THE MANUFACTURER HAS YET TO VERIFY/CORRECT THE PROBLEM. *TR

MILD TO SEVERE SURGING ISSUES WHEN RIDING THROUGH ALTITUDE CHANGES. THE BIKE FEELS SLUGGISH AND ACTS AS THOUGH IT'S RUNNING OUT OF GAS FOR ANYWHERE FROM 1-4 SECONDS. ONCE THE SURGING BEGINS IT USUALLY CONTINUES UNTIL THE BIKE IS RIDDEN TO LOWER ALTITUDE (APPROX. < 1000') OR THE BIKE IS SHUT OFF/ON. STOPPING AND TURNING THE BIKE OFF/ON SEEMS TO RESETS THE ECM OR AT LEAST APPEARS TO FIX THE PROBLEM. OFF/ON ONLY TEMPORARILY FIXES THE SURGING PROBLEM FOR A FEW MINUTES UNTIL THE BIKE SEE'S SUB-1000' ALTITUDE CHANGE. *TR

SEVERE ENGINE SURGING AND COMPLETE LOSS OF POWER WHEN RIDING THROUGH VARYING ALTITUDES. BIKE ACTS LIKE IT'S RUNNING OUT OF GAS AND LOSES ALL POWER FOR 1-3 SECONDS THEN POWER COMES ON SUDDENLY ALMOST LIKE WOW. VERY DANGEROUS WHEN IT OCCURS IN CORNERS AS IT'S COMPLETELY UNPREDICTABLE TO THE POINT WHERE THE MOTORCYCLE IS NOT OPERABLE. *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
