150cc scooter swap

[Irv_Novick]

So I'm swapping engines on my scooter/redoing the entire wiring, I've run into a few issues. I'm using a 8 pin regulator/rectifier Like this one. my question is do i still need to use a voltage regulator like This . I have both sitting around and I'm not sure if used both on the last engine...or if i just have spare parts sitting around. All wiring diagrams i look up only show the regulator/rectifier and no voltage regulator? I assume the 6 pin will take care of voltage regulating as well?
