Let's just cover everything again to make sure nothing is getting missed.

The solenoid has four connections. Two studs, each with thick wires attached. One stud goes to the battery positive terminal and the other stud goes to the starter motor. Doesn't matter which goes to which.

The other two connections are small wires that are used to activate the solenoid. Depending on how your controls are set up, there will be one of two situations:
1.) One wire on the solenoid goes to power (black wire in the harness) and the other wire goes to the yellow/red wire that leads to the starter button.
2.) One wire on the solenoid gets grounded (green wire in the harness or bare metal on the frame) and the other wire goes to the yellow/red wire that leads to the starter button.

If the solenoid clicks when you press the starter button, you know you have it wired correctly.

If the starter is not working when the solenoid clicks, you have one of the following scenarios:
1.) Starter is non-functional (I believe we've ruled this out because you can use the starter to turn the engine over if you connect it directly to the battery, but it still might be worth bridging the solenoid studs with a wrench just so we can rule out bad cables, too).
2.) Solenoid is non-functional. Two bad solenoids is unlikely, but possible.
3.) Bad starter button. I had this problem on my CX500. The solenoid would click, but the starter button was on the way out, so I wasn't getting enough current to get a solid switchover from the solenoid. I'd get the click, but a poor connection. We've ruled this one out by jumping the thinner solenoid wires that I had mentioned a few posts ago.
4.) Bad battery. I think we ruled this one out already as well? Jumper cables from a car battery is the way to check this.

So assuming that we've checked everything in step number one, I can't think of anything else it might be besides a bad solenoid.

Are all my assumptions and statements correct so far?

Yep you are correct.

OK... and just to be 110% sure: The starter will turn if you bridge the solenoid studs with a wrench?

No, the starter will not turn if you bridge the solenoids. That's why I didn't think it was a solenoid issue. Which is why I keep going back to a bad ground. That's my only thought

OK. That clears a few things up.

Starter will turn (while installed in the engine) if you connect it directly to battery positive using the cable that's currently attached to the solenoid?

With the starter on the engine. I took red jumper cable to the starter post, and black jumper cable to engine. And from there the starter turned.

Another thought.. Is after I painted the frame, and rebuilt the engine I never removed any paint from any of the engine mounts.. So could this be the problem? The engine isn't grounded to the frame?

It's a consideration, yes. Try your jumper cable technique again, but do only the positive side from your battery to to the starter motor.

Word, will do as soon as I get home.

Just cause I haven’t said it in a while, thank you for sticking with me through this. I appreciate more than I can possibly convey.
That goes to everyone who has provided input, y’all are some cool dudes.

My brother was at my house so I called him and had him do that for me cause I was anxious.
The starter turned when he connected the battery to the starter with only the red cable to the starter post and the positive battery terminal...
so does this mean the engine is in fact grounded to the frame properly?

Sounds like it to me, yes.

And we've already bridged the studs on the solenoid and didn't get the starter to work.

So sounds like a problem with one of the cables, I think. Either the one from the battery positive terminal to the solenoid or the one from the solenoid to to the starter motor.
