2007 YAMAHA FJR13 Fuel System, Gasoline Problems

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

Mileage: 15,000

WHEN THE ENGINE IS DECELERATING OR BRAKING FUEL IS TURNED OFF AND WHEN TRYING TO ACCELERATE AGAIN THERE IS A DELAY IN FUEL DELIVERY. WHEN TRYING TO ENTER A HIGHWAY FROM THE RAMP YOU DECELERATE TO TIME YOUR ENTRANCE AND WHEN YOU ACCELERATE THE MOTORCYCLE PAUSES THEN LURCHES FORWARD EFFECTING YOUR MERGE INTO SPEEDING TRAFFIC. THIS ALSO HAPPENS TO A SMALLER DEGREE ON EACH SHIFT OF THE TRANSMISSION. IT APPEARS THAT AN AIR PRESSURE SENSOR IN THE INTAKE MANIFOLD PREVENTS THE FLOW OF FUEL DURING INCREASED VACUUM AND THAT THE FUEL IS NOT TURNED ON AGAIN UNTIL THE VACUUM IS REDUCED BY AN OPEN THROTTLE. YOU OPEN THE THROTTLE, THE VACUUM GOES DOWN THE FUEL TURNS ON AND THE MOTORCYCLE LURCHES FORWARD. *TR

I HAVE A YAMAHA MOTORCYCLE THAT I PURCHASED IN MARCH OF THIS YEAR THAT EXHIBITS A SERIOUS PROBLEM WITH THE FUEL INJECTION SYSTEM. I HAVE CONTACTED THE DEALER WHERE I PURCHASED THE MOTORCYCLE AND THEY TOOK NO ACTION. I HAVE CONTACTED YAMAHA DIRECTLY. THE PRODUCT SPECIALIST I SPOKE WITH IN CYPRESS, CA ADVISED THAT THEY WERE AWARE OF THE PROBLEM, BUT WOULD NOT OFFER ANY DETAILS ABOUT HOW YAMAHA PLANS TO CORRECT THE ISSUE. THE PRODUCT SPECIALIST FURTHER ADVISED THAT A SERVICE BULLETIN WOULD BE ISSUED TO DEALERS AND LETTERS WOULD BE MAILED TO CUSTOMERS WITHIN TWO WEEKS TO ONE MONTH, HOWEVER, I HAVE DISCOVERED THAT OTHER OWNERS WERE TOLD THE SAME THING MANY WEEKS AGO. THIS IS A SERIOUS PROBLEM THAT CAUSES THE MOTORCYCLE TO BE SEVERELY UNDER POWERED WHENEVER IT IS OPERATED AT HIGH ALTITUDES. THE FIRST TIME THAT IT OCCURRED I THOUGHT THAT I WAS RUNNING LOW ON FUEL, HOWEVER, THIS WAS NOT THE CASE AND THE MOTORCYCLE WILL EXHIBIT THESE SYMPTOMS ANY TIME THAT HIGH ALTITUDE ROADS ARE ENCOUNTERED. THIS IS ESPECIALLY TROUBLING AND FRIGHTENING WHEN IT OCCURS WHILE NEGOTIATING CORNERS OR STOP-AND-GO TRAFFIC SITUATIONS. I AM INCLUDING A LINK TO FURTHER INFORMATION: HTTP://WWW.FJRFORUM.COM/FORUM//INDEX.PHP?SHOWTOPIC=23179 THANKS IN ADVANCE FOR LOOKING INTO THIS MATTER. THE DATE THAT I AM ENTERING BELOW IS THE MOST RECENT INCIDENCE.*JB

ALTITUDE-RELATED STALLING AND SURGING. *TR

WHILE RIDING THE MOTORCYCLE IN QUESTION IN THE MOUNTAINS THE ELEVATION ABOVE SEA LEVEL CHANGED FROM 1500 TO 5000 FEET AND DESCENDED AGAIN. WHILE ASCENDING THE MOUNTAIN AT LOW SPEEDS (25-30 MPH), THE ENGINE DID NOT RESPOND TO THROTTLE INPUT AND BEGAN TO STALL. RIGHT BEFORE STALL, THE ENGINE WOULD SUDDENLY ACCELERATE VIOLENTLY. CHANGES IN ALTITUDE OF APPROXIMATELY 800-1000 FEET SEEM TO CORRESPOND WITH THE PROBLEM. SHUTTING THE ENGINE OFF AND RESTARTING IT APPEAR TO RESOLVE THE ISSUE TEMPORARILY, THAT IS, UNTIL THE ALTITUDE CHANGES AGAIN. AS A RESULT OF THE BIKE'S ERRATIC BEHAVIOR, I NEARLY DROPPED IT TIME WHILE TRYING TO RE-ENTER THE ROAD FROM A PARKING LOT. TWO OTHER TIMES IT WAS DIFFICULT TO CONTROL WHILE NEGOTIATING LOW SPEED TURNS IN ON THE MOUNTAINSIDE. TO DATE, YAMAHA MECHANICS HAVE SAID MY CARBURETOR NEEDS TO BE ADJUSTED. HOWEVER, IT IS DIFFICULT FOR THEM TO REPEAT THE PROBLEM BECAUSE WE ARE AT SEA LEVEL WITH NO SIGNIFICANT ELEVATION CHANGES WITHIN REASONABLE DISTANCES FOR THE MECHANIC. *TR

MY 2007 YAMAHA FJR 1300 MOTORCYCLE PURCHASED IN MAY 2007 HAS A VERIFIED INABILITY TO DEAL WITH ALTITUDE CHANGES OF 2000 FT. OR SO IN EITHER GOING UP, OR DOWN IN ELEVATION. DURING THE PERIODS THE MOTORCYCLE HESITATES AND THEN SURGES DURING THESE PERIODS. THIS IS ALLEVIATED BY PULLING OFF THE ROAD AND THEN RESTARTING THE ENGINE, BUT THE ACT OF HESITATING/SURGING WHILE GOING AROUND CORNERS AT SPEED LIMIT CAN BE DANGEROUS BOTH THE RIDER, VEHICLES BEHIND THE RIDER, AND POTENTIALLY TO ONCOMING TRAFFIC. THIS ISSUE HAS BEEN RECOGNIZED BY MY DEALER, DESERT VALLEY POWERSPORTS OF PROSSER, WA. AND REPORTED TO YAMAHA CORPORATION. I HAVE REQUESTED SEVERAL TIMES TO HAVE THIS ISSUE FIXED AND AM TOLD THAT THEY KNOW OF THE ISSUE, THERE IS NOTHING THEY CAN DO ABOUT IT, AND YAMAHA IS WORKING ON A FIX. SEPARATELY BY ANOTHER DEALER I AM TOLD THAT THIS WON'T BE FIXED BY YAMAHA AND IS AN ISSUE WITH THE 2007 MODEL. *TR

WHILE ON A 5 STATE TOUR ON OUR MY MOTORCYCLE THIS SUMMER. MY FUEL SYSTEM SEEMED TO DANGEROUSLY SURGE. THE BIKE WOULD JUST SLOW DOWN AND THEN TO RECOVER I COULD GIVE MORE THROTTLE. WITH NO RESPONSE, THEN MORE THROTTLE AND THE BIKE WOULD JUST TAKE OFF. THIS ONLY HAPPENED WHEN I WAS CHANGING ALTITUDE. CHANGING UP HILL AND CHANGING DOWN HILL. ON MOUNTAIN ROADS IN COLORADO IN A 15 MILE PER HOUR CORNER AND YOUR BIKE JUST QUITS MAKING POWER THEN SUDDENLY RECOVERS WITH ALMOST FULL THROTTLE. WE ARE LUCKY MY KIDS STILL HAVE PARENTS. *TR

AT ELEVATION CHANGES, THE MOTORCYCLE HAS PERIODS OF SURGING, SOMETIMES PRODUCING VIOLENT THROTTLE RESPONSE. THIS COULD CREATE A VERY DANGEROUS SITUATION IN A CURVE OR WHILE PASSING. *JB

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) 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

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

WHEN RIDING IN THE MOUNTAINS WITH ELEVATION CHANGES OF 1000 FEET. OR MORE, THE MOTORCYCLE HAS PERIODS OF ZERO THROTTLE RESPONSE. THEN ALL AT ONCE IT WILL COME ON THROTTLE AND TAKE OFF VIOLENTLY. THIS IS A VERY DANGEROUS SITUATION WHEN IN THE MIDDLE OF A CURVE OR TRYING TO TAKE OFF FROM A STOP. *AK

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 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
