CDI coil combo 150cc/49cc (adjustable timing advance)
This is the ultimate GY6/QMJ157 150cc and QMB139 50cc CDI box. It comes as a CDI and coil in one. This is a micro processor CDI box. You can advance the timing with the turn of the knob, the rev limiter is removed, and delivers a 32,000 volts at the spark plug. Don’t get zapped :-I ! The installation is a breeze. The blue wire gets plugged into the pickup wire on your stator, the black wire gets grounded to the engine, and the red wire is wired to your kill switch or taillight with the supplied connector. This is not plug and play, but very close. If your building your own wiring harness this makes life super easy!
