Have an 1986 Honda Spree. All of a sudden no spark. New coil, new CDI, kill switch good. How do I check to see if the stator faulty?

Could be the stator or the regulator/rectifier.
You need a multimeter.
Check the voltage to the battery first, should read about 13.5V-14.5V with the engine RUNNING (ha-ha).
Check the voltage from the stator to the rec/reg engine running.

So, replace the reg/rect first and hopefully that's good,
If not the stator is next.

Could be something as simple as a defective spark plug cap.

Don't waste your money buying unnecessary parts.
The regulator/rectifier is only used to charge the battery.
It has absolutely nothing to do with the spark plug firing.

There's a "pulse coil" near the stator.

It acts like a set of points and tells the coil when to fire the spark plug.
A service manual is necessary to learn of the specs to test it.

Now you wanna check stuff? Thought you were using the random replacement method of troubleshooting. You sure it ain't got a magneto with, like, a lighting coil? Hazya got a shop book? Them's got troubleshootin' and, like, circuit descriptions, dude.
