2006 Suzuki GSX-R600

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. THIS CAUSES AN UNCONTROLLABLE SHAKE OF THE MOTORCYCLE AND COULD POTENTIALLY CAUSE GREAT DAMAGE AT HIGH SPEEDS. 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

I HAVE A SUZUKI GSXR 600 MOTORCYCLE AND WHEN I GIVE THROTTLE INPUTS, USUALLY WHEN MY BIKE HAS BEEN WARMED UP AND RIDDEN, IT GETS VERY JERKY AND GIVES TOO MUCH GAS TOO SUDDENLY. THEN WHEN I EASE OFF THE THROTTLE IT COMPLETELY CUT OFF. THIS MAKES OUT FOR A VERY "JERKY" RIDE AND MAKING IT DANGEROUS AND POSSIBLE TO CRASH DUE TO LACK OF CONTROL. MANY PEOPLE CALL THIS THE "HERKY JERKY" AS THIS SEEMS TO BE A PROBLEM WITH MANY PEOPLE I KNOW WITH THE SAME BIKE. *TR

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

I PURCHASED IT NEW AND IT NOW HAS OVER 6000 MILES. THE TRANSITION FROM OFF THROTTLE TO SLIGHTLY ON THROTTLE OR THE OTHER WAY AROUND IS EXTREMELY JERKY. IT IS VERY ANNOYING. I HAVE HAD THIS PROBLEM FOR MOST OF THE TIME THAT I HAVE OWNED THE BIKE. I AM A VERY EXPERIENCED RIDER, STREET AND TRACK, (10 YEARS AND 160,000 MILES) AND HAVE OWNED SEVERAL OTHER BIKES, BUT ON THIS BIKE, THERE IS NOTHING I CAN DO WITH MY THROTTLE HAND TO TRANSITION SMOOTHLY FROM OFF THROTTLE TO SLIGHTLY ON THROTTLE. WHEN GOING STRAIGHT, I CAN BE DECELERATING OR ACCELERATING, BUT I CAN NOT HOLD A CONSTANT SPEED - I HAVE TO ALTERNATE BETWEEN ON AND OFF THROTTLE AND EACH TRANSITION INVOLVES A BIG JERK. SMOOTH THROTTLE OPERATION IS ONE OF THE MOST IMPORTANT ASPECTS OF PROPER STABILITY OF A MOTORCYCLE DURING CORNERING. THE TRANSITION FROM OFF THROTTLE TO SLIGHTLY ON THROTTLE WHILE LEANED OVER IS SO JERKY THAT IT CREATES A MAJOR MID-CORNER DISTRACTION AND IS VERY UNSETTLING. THE PROBLEM OCCURS IN ALL GEARS AND ALL RPMS AND IN VARIOUS WEATHER CONDITIONS. ABOUT 80% OF THE TIME THAT I AM RIDING THIS BIKE I HAVE TO DEAL WITH THIS ANNOYANCE. THE OTHER 20% IT WORKS WONDERFULLY. USUALLY WHEN I FIRST START THE BIKE AND DRIVE OFF IT WORKS FINE, BUT WITHIN A FEW MINUTES THE JERKY THROTTLE PROBLEMS BEGIN. SO FAR I HAVE NOT BEEN ABLE TO SOLVE THIS PROBLEM.
