My GSXR 1000 is having problems when I get between 5-6 grand on RPM. It goes from being at 6 grand to 0, almost like the bike is cutting off but it doesn´t. It drops to 0 for a few seconds and then goes back to working correctly. Yesterday I just held in the clutch and reved it up a few times and it was acting like it was gonna cut off or sounding like it wasn´t getting enough gas or something.
