Relist your new parts, I couldn't make it out from your post.
Wire colors usually are:
Single phase, half wave:
Pink. Same as white. The lighting circuit high output (charging)
Yellow. The lighting circuit low output (separate headlight circuit)
Black/red: AC CDI power (if you have AC CDI, not used on DC CDI)
Blu/wht: Ignition trigger pickup
Grn/wht: Normally ground would be grn, guess is this is gnd
Single phase, full wave:
Pink and yellow: two sides of lighting circuit
Rest: same as previous
You have to know if new CDI is AC or DC
New stator has to match flywheel
New stator has to match RR

On the electric:
Don't count your chickens till your done. Lots of configuration unknowns to start out with.
If your going to DC incandescent you have to consider the large load your putting on wires not sized for it, might have to upgrade some.
If going to LEDS, some are a small electrical load and you may get away with the existing gauge. Some have a fairly large load and you may have to upgrade wires.

I'm making an assumption that if you checked the pickup gap that you have inspected the flywheel's pickup pad?
And when your taking your meter readings do you have the pickup wiring connector disconnected?
Also look over the stator to chassis to green wire ground connection for the pickup.
"Charged the battery". That's a red alert. If you have a DC ignition you need a healthy charged battery. A shot charged battery won't do.
As Chewbaca says. new parts aren't a bad thing. I ordered up a whole replacement pack of the main parts. Helps a lot for troubleshooting and is pretty cheap.

Ok I was testing the stair voltage for the lights, the 3 pin connector. And it's jumping around and not giving a good reading. There's only 2 wires on the stator side of the connector, and 3 on the side that goes the the lights etc... The green wire is the one that's not on the engine side. No ground wire? Or is it behind the flywheel maybe? I'm gonna order a flywheel puller. Here's a link to the voltage reading on the stator. Bad ground? Or bad stator? If this video is you on your machine and if your measuring the stator lighting coil output then, your meter is set to read DC volts and it should be set to read AC volts. Magneto stators are alternators and output AC.
Also it makes a difference if you are measuring the stator output only with the plug disconnected or the stator/rr circuit inline with the plug connected.
Your stator ground would appear to be a chassis only (no wire). Confirm by metering a bare spot on the stator base (scrape through any varnish for the test lead) to a chassis ground point, battery - , starter ground, etc.

The thing is with these machines, half the electrical is on the powerplant and half is on the chassis. So these machines end up with some version of a combination of the two. Ask someone who attempts putting a new engine on a chassis. Its kind of a coin toss if the electrics on the engine will work with the electricals on the chassis.
Find a wire diagram on your machine and post.

Open up the machine and check all the wires as you mentioned.
Be sure to check the fuses with a meter, not just by looking at them.
Let us know what you find, it might help someone else out also.

Does it really have a starter/alternator combo? I haven't seen anything like that in years. If it were me I would disconnect the wires from the solenoid and touch them together then hit the starter button and see what happens. The solenoid just protects the starter button from high tension wear and one hit won't damage it. Starterator's (also known as starter/generators ) are alive and well. Brand new ones can be had and make good projects. I'm wondering if the combo referred to in this thread is maybe a "stator / alternator"

Your troubleshooting doesn't seem to match your description of the problem. Its good practice to review recent work when a new problem shows up but...
Why do you think a hot battery equals a bad solenoid?
Sounds more like a bad battery connection.
Could you hear the starter running when it wasn't supposed to?
You say you replaced with a good battery. How do you know its good and if it is, the solenoid wouldn't cause "no electrics"
I suggest that you carefully clean and inspect your wires and wire connections not forgetting the grounds.

Something to keep in mind is that at any particular valve position half the cam is the lobe and the other half is the flat. The valve gap will be the same anytime the valve is off the lobe.
The rocker arm should be loose when the valve is anywhere on the flat.
While I think it is good practice to use the flywheel marks and inspect everything possible, I think it helps to understand the works if you look at things from different perspectives. You should actually be able to set the lash simply by looking at the cam / valves. That's how its done on multiple cylinder engines.
Next time your in there take some time and play around. Turn over the engine and watch the cam / valves. As the lobe goes on the valve, you will see the gap disappear, then the valve moves away, then the valve moves toward, then the gap reappears. If you turn the cam maybe 30 degrees more just to be sure of being away from the lobe, you will find that gap to be the same anywhere along the flat.
Moral of the story is to learn the workings and use methods to double check when possible.

Yea well it wasn't really necessary for me to go shooting off my mouth considering some criticism of the earlier comment was probably justified.
Just burns my when someone misconstrues someone else's words, especially for politics.
I consider myself a moderate an am getting tired of the left wingnuts and the right wingnuts babbling on as if they speak for the country.
My political patience tank is about empty.

My wife still says all illegal aliens should be rounded up en masse and shot. well unless your wife is a native american----she's a alien !!!!!!! Ahh! A zealot cherrypicking someones words, nice. Jarlaxle clearly said ILLEGAL. Enough with all the PC BS, Native American's are aliens like everyone else. As far as the native part goes, I'm not a American Indian but I am a native, I got me a legitimate birth certificate to prove it.

Funny all the comments concerning Harley.
Harley lobbied for a tariff in the mid 80's against 750cc and up foreign motorcycles.
Harley got a market boost that they claimed they needed to avoid going out of business.
Foreign 750's became 700's to get under the tariff.
Honda built a huge plant in Ohio to make Goldwings and some others I think. They didn't have to pay tariffs on US built.
After some years the tariff expired and most involved considered it a success.
Don't seem so bad.
