i was out practicing and in the air it would cut out on me like i was hitting my rear brake as hard as i could. i tryed to accelerate on the ground it would go fine then bog out after a few 1000rpms. i figured plugs but noticed the next day that my fuel pump didnt do the high pitch noise, it still primes but sounds very sluggish and weak. i figure a bad connection or relay would cause the pump not to prime at all? so is the pump its self bad then? my battery is good and the bike fires but then dies. anybody delt with this problem or know whats wrong?
