My 1998 CBR 600 will run right through first and second gear with no problems at all. But once I hit third and give it gas it sounds like its out of fuel. Jerking and slowing down. Its got fresh gas and the carbs and fuel filter are clean. What else could it be? Is my air to fuel mixture not correct? Could it be the coils? Any help would be great. Thanks. Wanna kill these ads?
