Got a 04 zx10. hear this howling sound from 20mph to 30ish. second or third gear. other speeds or gears i dont hear it much. called kawasaki and they said it was my alternator. they said they have had some issues with this. i been riding it like this for the past 50 or so miles. i heard from other sources that the alternator could grenade and cause all types of motor problems. has anyone had this issue or hear of it? kawi said they help me out even though its 5 yrs out of warranty. Question....if an alternator say did grenade and destroyed the motor..think kawi would give you a new motor??
