911 PLEASE HELP. I’ve replaced stator/ magneto. New plug, CDI, coil and starter relay. I had it stared but it died, now no spark and my CDI no longer lights up. What do I do now?

You said that your CDI no longer lights up? is that one of the "racing" replacements with the little LED that flashes?
If so, that would be my first suspect. Try the stock CDI and see if it works. You changed a lot of parts, go back over everything and check connections etc.
I was once right where you are, chasing an intermittent no spark issue on a brand new machine. Replaced everything before finding a bad connection inside of the handlebar harness.

Roon Is right it could just be as simple as a ground wire came loose.
Go slow and retrace steps ,I would work backwards starting at the plug Look for loose connections, rotted wires . Swap back parts that you know were working one at a time .

Look at the wiring diagram on site, pick one... there is one showing the CDI connections and what they are for. Or look on the web. If you can, remove the wire connector from the plastic carrier for the KILL wire. See if you get spark.
It is very possible that the 'kill' switch on the handle bar, or elsewhere, has bad gizzards and is grounding the CDI so it won't function, and this will help determine if the NO-SPARK is caused by faulty CDI or bad pickup/power from the stator. IOW if it fires with the kills(handlebar and ignition) disconnected, they are then the new suspects. tom
