Question about Suzuki Motorcycles
1981 Suzuki gn400 I have 6 volts power coming out of my CDI to the ignition coil but then power drops off to the spark plug and won't create spark.. Brand new ignition coil and plug and ive ran new wires. Also cleaned all ground connections. I've even studied the wiring diagram and I'm stumped.. Plz help..
I know it sounds silly, but have you checked your earth or ground wiring. If not earthed this type of problem can occur. Did the bike run before you replaced your coil etc? You could have a crook CDI
are you using multi meter mate for correct voltage readings?

Hi and welcome to FixYa,
The voltage on the green wire must be pulsating when cranking/starting the bike, not steady. Confirm by similarly testing the voltage on the black wire on the left ignition coil. If the green still reads a constant voltage, then the CDI is faulty; to be more specific, most likely that the switching tansistor inside the CDI that drives the right ignition coil has shorted.
Good luck and thank you for asking FixYa.
