Oil changes should be more than simply changing the oil and filter. Look around to make sure you don't have any chaffing wires, bolts coming loose, leaks, etc. :cheers. Currently riding a '05 GSXR 1000 ~ Full Tit. Akrapovic, PowerCommander, Schnitz Racing Custom map = 166horse.
Marty has hit the nail on the head Marty's comments about changing the oil is the same experience that I had. After the first service my GSX-S had a horrible gear change and it was hard to find neutral. I changed to Fuchs oil and it was all sweet again. Oils ain't oils. It's probably time to do the clutch adjustment in the motor as well. Find and hold the “Select/Reset” button down for ten seconds. Watch for the oil change light to start blinking. When it starts blinking, release the button then press it back down for another 10 seconds until it reads 100%. For some displays you may need to select the “Info” button to enter reset mode. NfqyX9g.
