Cdi Derestricted Naraku Racing GY6 With Ac Ignition

Open, non-restricted Racing CDI from Naraku for Chinese 50cc 4-stroke scoots with 139QMB/QMA engine and twin plug.This ignition unit has a little adjustment screw to change the ignition point. By turning the screw clockwise, you can advance the ignition; by turning it anticlockwise, the ignition is retarded. This way you can influence acceleration and engine running. This makes sense especially for tuned two-wheelers with increased capacity. The CDI comes with the screw in middle position. There are 12-13 complete turns possible in both directions. You hear a slight clicking noise when the stop has been reached.
