Then I would say the CDI was grounded.

You said NO SPARK, the only way the ignition would have anything to do with it not starting is it was grounding the CDI which is what it does when you turn it OFF JUST like the KILLSWITCH
OR IF THE CDI IS A DC CDI. IF its a DC CDI then when you put the KEY on IT SENDS 12V to the CDI.
That right there tells me you never pulled the KILLWIRE off the CDI.

Come on Millsc, So your telling me you pulled the Killwire off the CDI and it still would not start. Then you plugged it back in and unplugged the ignition and it starts Now that is some magic stuff going on. I was born late but not yesterday  The killwire all it does it GROUNDS OUT THE CDI no more no less. If the wire is grounded on the other end it will not FIRE. So unhooking the KILLWIRE FROM THE CDI should have eliminated the IGNITION SWITCH AND the KILLSWITCH from grounding out the CDI. Just so you know what it does and how it works. You can run any SCOOT without the ground wire the problem is you cannot shut the motor off with the KEY OR KILLSWITCH because now there is nothing to ground out the CDI. Alleyoop |

Just wanted to explain how it works so others may benefit from knowing how it works.

Just to reiterate for others to understand what part the ignition plays with a CDI.
1. Grounds out the CDI to kill the motor when you turn the key off JUST LIKE THE KILL SWITCH.
2. Feeds 12v to the CDI when on the ON POSITION IF the CDI IS a DC CDI.

I read this 3 times and the best theory I could come up with is you had a combination of problems: Bad pickup coil Bad ignition switch Alley hit the nail on the head and I only know of two 50cc scooters that have a DC type CDI and this isn't one of them so that part of the equation is out. Either the AC feed or the pickup coil feed to the CDI wasn't making a good connection and you removing or replacing the kill wire helped make the other wires make a good connection or you mistaken the kill wire for another, or the kill wire was in the wrong spot?  That's the only scenarios that I can think of that would cause this. *) Either way the good thing is the scooter is running.  JR |

I think the previus owner had it rigged, but whatever the case it was a successful repair, they came all the way from iowa almost three hour drive  |
