2007 Suzuki GSX-R600 Transmission and drivetrain Problems

“The factory service manual lists the torque for the rear sprocket nuts as 67.5 ft-lbs. The motorcycles were build with this spec! This is incorrect and is corrected with a Suzuki service bulletin(but not a recall to current owners!). Depending on the luck, but probably you will just shear the threads and end up with a spinning loose sprocket & nut. A stud can break off the sprocket under pressure and cause the chain to break free causing a rear wheel to lock thus resulting in a serious accident, or to cut the rider's let leg while driving at a high speed. …”

“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. …”

“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.”
