NHTSA complaint #11173426 — an unverified report by a vehicle owner.

FUEL SYSTEM, GASOLINE

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. THIS COULD BE FROM A RUSTING THROTTLE CONTROL VALVE THAT IS NOT OPENING CORRECTLY. THE BIKE WAS STORED INDOORS AND RARELY SAW RAIN, SHOULD NOT BE RUSTING.

FUEL SYSTEM, GASOLINE

I HAVE CUT AND PASTED THE COMPLAINT OF A FELLOW FORUM MEMBER SINCE OUR PROBLEMS ARE THE SAME. PLEASE HELP US RESOLVE THIS ISSUE. 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.

FUEL SYSTEM, GASOLINE

"HERKY-JERKY" IS WHEN FUEL SHUTS OFF AT 1-5% THROTTLE, NOT 0%. THEN IT DOES NOT COME BACK ON UNTIL 5%+ THROTTLE. IT IS IMPOSSIBLE TO HOLD A STEADY THROTTLE BETWEEN 1-5% THROTTLE NO MATTER WHAT GEAR OR WHAT SPEED.

FUEL SYSTEM, GASOLINE:FUEL INJECTION SYSTEM

WHEN IN MOTION, AT VARYING CONSTANT SPEED, AS THROTTLE IS OPEN AND HELD AT ABOUT 10%, MOTORCYCLE ENGINE WOULD BUCK ON AND OFF REPEATEDLY UNTIL YOU EITHER ACCELERATED OR CHANGE GEAR. THIS IS A VERY DANGEROUS BEHAVIOR WHEN GOING AROUND A CURVE AS THE ON OFF SENSATION IS VERY ABRUPT AND CAN UNBALANCE THE HANDLING OF THE BIKE.
