Okay so I am working on a 2019 Kymco Agility 50 10k miles no aftermarket instals I am very mechanically inclined it is not my personal scooter I have replaced the stator with one from the dealer I replaced the CDI with the one from the dealer same with the regulator AND the coil AND IT STILL WONT SPARK spark plug is brand new and the one it calls for yes the switch and ignition is in the on position I even went as far as adding 2 new grounds, one to motor and one to frame. can somebody please help me out here before I rip my freaking hair out

Have you actually checked anything other than replace parts? Did you check the stator with a meter?
Check the coil resistance and the distance from the stator pickup too.

ALWAYS find the fault first before wildly replacing parts. Replacement parts can often be faulty.
There are troubleshooting charts in the service manuals you can download here. Follow the charts step by step and DO NOT skip any steps.

see thats the thing I HAVE done all the necessary testing, stator and pickup are working fine, wire from the cdi to the coil is sending power, the only thing I haven't replaced is the condenser, would that cause no spark?

the stator for this specific moped is strange, it only has 2 wires leaving it, one is white and other is yellow, but the black/red wire going to the cdi still reads power

Stator wiring sounds standard, not "strange". There are more than two wires. Follow the steps in the trouble charts exactly.

If you disconnect the wires to the ignition switch, the CDI will/should fire and you will be unable to stop the running engine without smothering its air or fuel supply. The ignition is a KILL switch, grounding the CDI output. Unless you have a DC volt CDI, the stator will provide voltage to operate the CDI circuit. The pickup coil mounted external to the flywheel will generate a signal to the CDI to discharge and generate coil voltage. A ground/shorted capacitor/condenser could absorb all the CDI output, and thus prevent coil operation. A bad SECONDARY (fat) wire that has multiple breaks could provide too much gap(even internal) for the CDI provided voltage to jump the gaps and the spark plug gap. Measure the resistance of the plug wire. Be sure every component involved is grounded as designed, with no loose connections or frayed wires. Damaged insulation can ground things that should not be grounded. Checking terminals connection to ground(one VOM pin on terminal and the other to ground), if you have measurable ohms, there is a wiring problem between the terminal and the other end... tom

the last time I had that issue the connectors on the coil weren't tight. one was really bad. I did the squeeze with pliers. after that, it ran great.
