2007 YAMAHA FJR13 Engine And Engine Cooling Problems

ENGINE SURGES ABOVE 3000 FEET ALTITUDE CAUSING UNCONTROLLED LIFTING OF FRONT WHEEL IN FIRST AND SECOND GEAR. *TR

BRAND NEW 2008 YAMAHA FJR1300A. ENGINE FREQUENTLY STALLS UPON APPLICATION OF THROTTLE FROM A DEAD STOP. HAPPENS HOT OR COLD. THIS IS A VERY DANGEROUS DEFECT; IF I WERE ATTEMPTING TO GET OUT OF THE WAY OF A CAR I'D BE HIT AND INJURED. THERE IS AN OPEN INVESTIGATION THAT APPEARS TO BE SIMILAR TO WHAT I'M EXPERIENCING: PE 08048. *TR

I PURCHASES A BRAND NEW 2007 YAMAHA FJR1300 FROM OTD MOTORSPORTS IN MARINA DEL RAY CALIFORNIA. THE MOTORCYCLE HAD 1 MILE ON THE ODOMETER. AFTER RIDING THE BIKE FOR A COUPLE OF WEEKS A BAD ENGINE SURGE BEGAN TO APPEAR. NOT A NORMAL SLOW METHODICAL BOOST OF ENERGY BUT A SUDDEN ALMOST OVERWHELMING BOOST OF POWER. IT WOULD CONSISTENTLY HAPPEN DURING THE TRANSITION BETWEEN DECELERATION AND ACCELERATION. SEVERAL TIMES WHILE HAVING A PASSENGER ON THE BACK OF THE BIKE, SHE ALMOST FELL OFF DUE TO THIS POWER SURGE. I TOOK IT TO HOUSE OF MOTORCYCLE IN EL CAJON CALIFORNIA TO HAVE THEM LOOK AT IT. SEVERAL TECHNICIANS TOOK THE BIKE FOR A RIDE AND FOUND THE SAME DANGEROUS ISSUE. AFTER TALKING WITH YAMAHA CORPORATION IN CYPRESS CALIFORNIA IT WAS CONCLUDED THAT THIS WAS A "QUIRK" OF THIS MODEL AND YEAR OF BIKE AND THERE WAS NOTHING THEY COULD DO. THE...

THIS IS RELATED TO THE NEW YAMAHA 2007 FJR1300A. THE ECU DOESN'T APPEAR TO TAKE REALTIME BAROMETRIC READINGS. THIS IS VERY APPARENT WHEN YOU CHANGE ALTITUDE ON MOUNTAIN ROADS, WHICH CAUSES A VERY UNSAFE CONDITION WHERE THE MOTORCYCLE HESITATES WHEN THROTTLE INPUT IS APPLIED. THE HESITATION GETS LONGER THE HIGHER YOU GO. IT IS A CONSISTENT, REPEATABLE ISSUE, AND HAPPENS EVERY TIME I RIDE IN THE MOUNTAINS. I HAVE REPORTED IT TO YAMAHA, BUT THEY DENY THE ISSUE EXISTS. *TR

ALTITUDE ABOVE 1500 FEET, BIKE SURGES AND FEELS AS THOUGH IT WOULD STALL. TOOK TO DEALERSHIP WHO ADJUST THROTTLE. NEXT RIDE BETWEEN 1500 AND 7000 FEET BIKE CONTINUED TO SURGED AND LOSS POWER GOING AROUND AN INCLINE CURVE. HAD TO PULL OVER AND SHUT DOWN THE ENGINE. SERIOUS SAFETY ISSUE. *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

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

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
