2007 Suzuki GSX-R600

THE PROBLEM HAS BEEN LABELED THE "HERKY JERKIES". WHILE RIDING AT ANY RPM WHEN THE REAR WHEEL SPEED MATCHES ENGINE SPEED THE THROTTLE SHUTS OFF ABRUPTLY WITH NO WARNING, THROWING YOU FORWARD OVERLOADING THE FRONT WHEEL. WHEN THE WHEEL SLOWS ENOUGH THAT THE ECU CALLS FOR FUEL IT DELIVERS A LARGE AMOUNT OF FUEL AND THE BIKE JERKS FORWARD UNLOADING THE FRONT WHEEL CAUSING AN UNRECOVERABLE FRONT WHEEL SLIDE (WHILE LEANED OVER IN A TURN). THERE IS A LARGE AMOUNT OF PEOPLE INCLUDING MYSELF WORKING ON THE PROBLEM, WE HAVE DISCOVERED WAYS TO MASK THE PROBLEM BUT NO RESOLUTION TO DATE. SUZUKI HAS RECEIVED MANY COMPLAINTS AND IS NOT DOING ANYTHING ABOUT IT. I HAVE CALLED IN NUMEROUS TIMES STARTING SOME TIME AROUND MARCH. I HAVE BEEN WORKING WITH PEOPLE ON GIXXER.COM IT'S A FORUM FOR GSX R OWNERS AND THERE ARE MANY THREADS CONCERNING THIS ISSUE. I / WE ARE HOPING THAT YOUR ORGANIZATION WILL BE ABLE TO SOLICIT A RESPONSE FROM SUZUKI, SEEING AS THOUGH THEY ARE IGNORING US. *TR

ABRUPT ON/OFF THROTTLE CAN CAUSE SUDDEN AND UNEXPECTED RAPID DECELERATION AND ACCELERATION, DESTABILIZING THE VEHICLE POTENTIALLY LEADING TO LOSS OF CONTROL AND A CRASH. THE PROBLEM SEEMS TO OCCUR AT LOWER ENGINE RPM'S (4,000-6,000 RPM) AND SEEMS MOST PREVALENT AT HIGH ENGINE TEMPERATURES (205+ DEGREES) AND ESPECIALLY WHEN THE VEHICLE IS TURNED ON AND STARTED WHILE AT HIGHER TEMPERATURES. *TR

A FAST ON/OFF OF THE THROTTLE CAN CAUSE AN UNEXPECTED DECELERATION FOLLOWED BY A RAPID ACCELERATION MAKING THE BIKE FEEL UNSTABLE. DOESN'T OCCUR VERY OFTEN. THE MAJORITY OF THE TIME IT SEEMS TO HAPPEN BETWEEN ABOUT 4-6K RPM WHEN THE BIKE IS 150+ IN TEMP. THE COMPLETE NOTE/TONE OF THE BIKE WILL CHANGE AND IT CAN MAKING PASSING/DRIVING UNCOMFORTABLE. *TR

PEOPLE THAT I'VE TALKED TO WITH THE SAME BIKE AND PROBLEM ARE MAKING ADJUSTMENTS THAT ARE NOT RECOMMENDED BY DEALERS TO GET RID OF THE PROBLEM. *TR

THROTTLE PROBLEM, WHEN RIDING MY MOTOR CYCLE BETWEEN THE RPM'S AROUND 35,00RPM'S AND 55,00RPMS MY THROTTLE WILL CUT OF DRASTICALLY WITH BARELY ANY HAND MOVEMENT OF LETTING OFF THE THROTTLE. BY LETTING OFF JUST A LITTLE BIT THE SPEED OF THE BIKE IS DRASTICALLY REDUCED BY SLOWING DOWN, THE SAME HAPPENS WHEN GIVING THROTTLE. THE SPEED OF THE MOTORCYCLE WILL INCREASE SUDDENLY CAUSING A SUDDEN LEAP IN SPEED. THIS CAN CAUSE A CRASH IF LETTING OFF THE THROTTLE IN A CORNER WITH THE SPEED INCREASE OR DECELERATION. *TR

TL*THE CONTACT OWNS A 2007 SUZUKI GSX-R600. WHILE DRIVING 60 MPH, THE SPEEDOMETER WOULD NOT FUNCTION CORRECTLY AND WOULD DISPLAY APPROXIMATELY 7-9 MILES OVER THE ACTUAL SPEED. THE MILEAGE INDICATOR WOULD ALSO DISPLAY A HIGHER MILEAGE THAN WHAT WAS ACTUALLY ON THE VEHICLE. THE DEALER STATED THAT THEY WOULD ATTEMPT TO REPLACE THE SPEED SENSOR. WHEN THE CONTACT RETRIEVED THE VEHICLE, THE DEALER STATED THAT THE ISSUE WAS CORRECTED AND WOULD ONLY READ 1 MPH OVER THE ACTUAL SPEED. WHEN THE CONTACT TOOK THE VEHICLE HOME, SHE NOTICED YET AGAIN THAT THE SAME FAILURE OCCURRED. SHE RETURNED TO THE DEALER AND THEY STATED THAT IT WAS ACCEPTABLE FOR THE SPEEDOMETER TO BE OFF APPROXIMATELY 10% OF THE ACTUAL SPEED. THE FAILURE MILEAGE WAS APPROXIMATELY 30. UPDATED 05/28/08 *BF

2007 GSXR 600 HAS SOME SORT OF FUEL INJECTION/THROTTLE PROBLEM. WHILE AT LOWER RPM'S, THE BIKE SHUTS OFF AND THEN COMES BACK ON CAUSING DANGEROUS UNSTABLE THROTTLE RESPONSE. IT HAPPENS WITH THE SLIGHTEST MOVEMENT IN THE THROTTLE AND WHILE ROLLING OFF THROTTLE, IT SLAMS THE BIKE FORWARD IN A JERKING MOTION AS IF THE BIKE HAS SHUT OFF. THEN, WHEN YOU GIVE IT GAS, IT THROWS YOU BACK IN THE SEAT BY COMING ON WITH FULL POWER. VERY STRANGE AND VERY DANGEROUS. DEALER SAYS THEY "DON'T KNOW HOW TO FIX THE PROBLEM" SEEMS AS IF A LOT OF OTHER SUZUKI GSXR OWNERS HAVE HAD THIS PROBLEM, SO I'M WONDERING WHY THERE IS NO FIX FOR THIS? VERY DISSATISFIED WITH MY 07 GSXR 600 AND IF THERE IS NO FIX, I WILL TAKE IT TO THE CLOSEST HONDA DEALERSHIP AND TRADE IT IN! THIS COULD EASILY CAUSE A CRASH IF ONE WERE TO NOT BE EXPECTING THE JERKING OF THE BIKE WHILE ON/OFF THROTTLE. VERY UNSTABLE POWER DELIVERY. *TR
