    I give up please help

    I have a 2007 Fz1 and it sputters at low rpm's only when completely warmed up, then under about 2500-3000 it runs bad occasionally dying and turns over about four seconds before starting. I've changed the coils and the plugs, waste of money cause I didn't help. My bike has 57.000 miles on it...
