I just purchased my zx9r and I´m loving it, however I have been told my regulator and rectifier are bad causing an overcharge to my battery! I am waiting on a book so I can learn more about my bike, but basically my question is I found a website that sells an aftermarket regulator/rectifier as 1 unit instead of two and its 1/6 the price of replacing the two original pieces! will this work? or what should I do? Thanks
