2007 Yamaha FJR1300

I HAVE A 100% STOCK 2007 YAMAHA FJR 1300 THAT JUST CROSSED THE 1,000 MILE MARK. I LIVE AT ~5,000 FEET ABOVE SEA LEVEL. IN THE FIRST FEW HUNDRED MILES OR SO IT SEEMED TO HAVE A SLIGHT HESITATION IN THE LOWER RPM'S (1,500 - 2,700), THAT SLIGHT HESITATION IS GETTING WORSE AND IS NOW PRETTY "JERKY". A FEW TIMES IT JUST SEEM TO STALL WHEN STARTING OFF. IT IS STARTING TO MAKE ME NERVOUS TO PULL OUT INTO TRAFFIC. *TR

MY 2007 YAMAHA FJR1300A MOTORCYCLE VIN # XXXXXA000627 EXPERIENCED SEVERE THROTTLE SURGING AS I DROVE UP AND DOWN FROM 0 TO 6700 FEET IN ELEVATION. DROVE FROM CORONA, CA TO BIG BEAR VILLAGE, CA AT THE TOP OF THE SAN BERNARDINO MOUNTAINS. STALLED OUT IN HEAVY TRAFFIC SEVERAL TIMES BUT NO CRASHES. DIFFICULT TO MAINTAIN SPEED. NO FUEL DELIVERY TO ENGINE ETC. FIRST THE ENGINE BOGS, THROTTLE DELAY AND THEN SURGES (REVS UP) AHEAD. *JB

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

1) THROTTLE FAINLS TO RESPOND PROPERLY WHEN ASCENDING TO A HIGHER ALTITUDE MORE THAN 1500FT HIGHER THAN THE STARTING POINT. 2) THIS HAS OCCURRED ON SEVERAL OCCASIONS. THE THROTTLE WILL FAIL TO RESPOND WHEN ADDING MORE THROTTLE. THE BIKE WILL BEGIN TO LOSS POWER UNTIL THE THROTTLE HAS BEEN TURNED TO ADD APPROXIMATELY 20% MORE, THEN IT WILL ACCELERATE ABRUPTLY. I HAVE RUN OFF THE ROAD ON A SLOW UPHILL CORNER WHILE TRYING TO KEEP UP WITH THE FLOW OF TRAFFIC. I ENDED UP BEING ABLE TO STOP BEFORE I CRASHED INTO A SNOW BANK. I HAVE EXPERIENCED THIS FAILURE ALMOST EVERYTIME I RIDE MY MOTORCYCLE INTO THE MOUNTAINS. THE MOTORCYCLE WILL ONLY BEGIN TO RESPOND CORRECTLY AFTER SHUTTING THE POWER OFF FOR ABOUT ONE MINUTE. 3) ADVENTURE MOTORSPORTS HAS DIAGNOSED THE ISSUE, AND TRIED TO MAKE ADJUSTMENTS TO CORRECT THE ISSUE. THIS HAS NOT HELPED. 46 OTHER OWNER HAVE REPORT THIS ISSUE TO ME AS WELL, THE LAST 6 DIGITS OF THEIR VIN'S ARE 000385 TO 003350 SO FAR. *TR

1) ENGINE FUEL CONTROL ISSUES WITH CHANGING ALTITUDE. 2) THROTTLE FAILS TO RESPOND TO INPUT UNTIL I INCREASE MORE THAN 20%. I THEN GET ALL 20% AT ONE MOMENT. I HAVE ALMOST CRASHED MY MOTORCYCLE WHILE RIDING IN THE MOUNTAINS OF CALIFORNIA AND WASHINGTON. I HAVE RUN OFF THE ROAD BECAUSE OF THE SUDDEN ACCELERATION. I WAS ABLE TO STOP UNHARMED DURING THAT INCIDENT. THE ENGINE CONTINUES TO RUN POORLY AFTER RETURNING TO THE ORIGINAL ALTITUDE I STARTED AT. 3) THROTTLE BODY ADJUSTMENTS HAVE BEEN MADE TO ADD MORE FUEL TO THE ENGINE ALL THE TIME. THIS HAS NOT HELPED. IT HAS JUST LESSENED THE SYMPTOMS, NOT FIXED IT. TURNING THE BIKE OFF FOR A 1 OR 2 MINUTES RETURNS THE ENGINE TO A PROPER RUNNING STATE. YAMAHA IS NOT ACKNOWLEDGING THAT THERE IS AN ISSUE, EVEN THOUGH MY DEALER (ADVENTURE MOTORSPORTS IN MONROE, WA) HAS RIDDEN MY MOTORCYCLE WHILE IT WAS ACTING UP. THIS ISSUE HAS BEEN REPORTED TO ME BY 46 OTHER OWNERS WITH VIN NUMBERS WITH THE LAST 6 NUMBERS OF 000385 TO 003350. *TR

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
