I have a small problem with my 98 ZX-6R. When I roll the throttle hard the motor die down for a second and then accelerates. I have this problem at all RPM but it the worst between 3500 and 9500 rpm. I don’t know if this is a zx-6r problem or what. I also ride a 97 Honda F3. (The Honda belong to my girlfriend but I take care of it) and that does not have this problem. I have tried several things to get the bike to hit harder and faster. New air filter, new plugs and rechecked the gap after a while. I also pulled the jets out and cleaned them, and that didn’t help the problem. I’ve also ran carb cleaner though the gas. I’m going to be putting a pipe and a jet kit on it this winter. Maybe that will stop the problem. But if anyone has any suggestions let me know.
