2007 Suzuki GSX-R750

TL*THE CONTACT OWNS A 2007 SUZUKI GSX-R750. WHILE TRAVELING AT APPROXIMATELY 45 MPH WITHOUT ACCELERATING, THE THROTTLE RELEASED IN A DOWNWARD SHIFT POSITION. THE VEHICLE JERKED FORWARD UNEXPECTEDLY. WHEN THE IGNITION WAS NOT TURNED OFF, THE VEHICLE WOULD RUN PROPERLY. THE CONTACT WAS CONCERNED OF THE SAFETY RISK INVOLVED. THE VIN WAS UNKNOWN. THE FAILURE MILEAGE WAS 700 AND CURRENT MILEAGE WAS 1,534.

2007 SUZUKI GSXR750 PROBLEM BEGAN WHEN BIKE WAS NEW FROM THE SHOWROOM AND CONTINUES TO THE PRESENT THE PROBLEM IS A RAPID AND ABRUPT THROTTLE CLOSING, AND IS OFTEN ENCOUNTERED WHEN THE MOTORCYCLE IS AT A CRUISING SPEED AND THE THROTTLE IS BEING MAINTAINED (THE BIKE IS JUST MAINTAINING SPEED, NOT ACCELERATING). WHENEVER THE THROTTLE IS MODULATED TO LESSEN THE SPEED, THE BIKE REACTS AS IF THE RIDER HAD JUST CLOSED THE THROTTLE COMPLETELY AND THE BIKE BEGINS TO ENGINE BRAKE, HARD. THE FAILURE, THE ABRUPT CLOSING OF THE THROTTLE DESPITE MINUTE ADJUSTMENTS TO THE CONTROLS, OCCURS OFTEN, BUT IT WILL HAPPEN ALWAYS OR NOT AT ALL AND SEEMINGLY WITHOUT REASONING AS THE BIKE'S ECU SHOWS NO ERRORS OR DEALER CODES AND ALL SYSTEMS RELATED TO THE FUNCTION OF THE THROTTLE HAVE BEEN CHECKED AND ARE IN SPEC. AS FOR THE FREQUENCY, THE BIKE WILL EXPERIENCE THE FAILURE 100% OF THE TIME THE SITUATION IS ENCOUNTERED IF THE BIKE HAS DONE IT AT ALL ON THAT RIDE. IF YOU START THE BIKE AND THE PROBLEM DOES NOT OCCUR, IT WILL NOT OCCUR AGAIN ATLEAST UNTIL THE BIKE IS STOPPED, SHUT DOWN, LET SIT, AND RESTARTED. HOWEVER AT THE SAME TIME, IF THE PROBLEM IS OCCURRING, IT WILL CONTINUE OCCURRING ATLEAST UNTIL THE BIKE IS SHUT OFF, ETC AND RESTARTED. WHEN TRAVELING IN A STRAIGHT LINE, THE PROBLEM IS MORE ANNOYING THAN ANYTHING ELSE, BUT IF THE MOTORCYCLE IS ENGAGED IN A LONG MEDIUM/HIGH SPEED SWEEPING TURN, AND THE RIDER ENCOUNTERS THE PROBLEM, THE RESULTS COULD BE RATHER CATASTROPHIC AS A SUDDEN DECREASE IN SPEED WOULD CAUSE A LOSS IN CENTRIFUGAL FORCES WHICH KEEP THE MOTORCYCLE BALANCED THROUGHOUT THE TURN. THIS PROBLEM COULD VERY WELL LEAD TO THE SEVERE INJURY/DEATH OF A RIDER EVEN WHEN UTILIZING THE MOTORCYCLE WITHIN STANDARD OPERATING PROCEDURE. *TR

GSXR 750 HAVING THROTTLE ISSUES AROUND 4,000RPM. POWER SHUTS OFF, THEN COMES BACK ON ABRUPTLY. FEELS LIKE BIKE IS STALLING, THEN START AGAIN. VERY DANGEROUS WHEN TURNING OR CRUISING AROUND TOWN WITH CARS BEHIND YOU WHILE YOU HAVE SUDDEN LOSS OF POWER. NO CAUSES FOUND AS TO WHY IT'S HAPPENING. SUZUKI DEALERSHIPS SHOULD RECALL THESE 2007 BIKES. THIS PROBLEM IS UNACCEPTABLE. I AM SELLING MY BIKE IMMEDIATELY. I FEEL IT IS UNSAFE TO RIDE IN THIS CONDITION WITH THROTTLE INSTABILITY. THIS HAPPENS IN EVERY GEAR AROUND 4,000RPM. DEALER CAN'T FIND A WAY TO FIX THE PROBLEM, AND I AM DONE WASTING MONEY TAKING IT TO A SHOP. SUZUKI NEEDS TO DO SOMETHING ABOUT THIS! *TR
