Wouldn’t this suggest the problem is in the final drive, not the engine side?

Could be but if the clutch lever is pulled in the kick starter won't turn the engine. He should take off both the sprocket cover and the clutch cover. Pics will help us spot something he may be missing.

I'm sorry. I took the sprocket cover off to take my stator cover off and everything looked fine under there. Took the clutch cover off and everything seems fine. Should I take the plates out and inspect them? Does this mean it's probably my transmission locking everything up?

So these are the basic symptoms.
I think "clutch engaged" means the clutch lever pulled so that the clutch slips.

The spark plugs are out and I can hear my engine give a little sigh and she gives me some resistance when I do it. I can go as far backward AND forward doing this as I want to.
My kickstart swings with an engaged clutch as well, idk if that matters.

My rotor moves with no hang ups using a socket and NO clutch - I hear the air from my pistons moving, and smell gas from my spark plug holes. I have to engage my clutch to roll the back wheel back and forth in gear (gives moderate but consistant resistance with clutch engaged), and to move my kickstart whatsoever

We know the bike can roll infinitely when in neutral since he pushed it home.

It seems the bike can also roll forward and backward with the clutch pulled while in gear, but with resistance.

The engine turns smoothly when the clutch is pulled or when in neutral.

So the crankshaft turns. The primary chain must move for this to happen. That means the clutch outer basket must turn.
Also, the wheel turns which means the sprocket turns. The sprocket is the output shaft of the transmission. The center of the clutch is the input shaft of the transmission. When in gear, with the clutch pulled, the wheel turns, which means the entire transmission is turning. I think that accounts for all of the shafts of the engine/trans are free and turning.

The kick start moves only when the clutch is pulled, regardless of being in gear or neutral, correct?

And please, can someone confirm my thinking above? I'm not very familiar with the 750 twin at all.

I'll try to find a manual to see how the kickstart engages the transmission. My pdf is pretty poor quality.
It looks like the kicker shaft engages the biggest gear on the trans output shaft which is first gear.
Unfortunately, it takes splitting the cases to get to that kicker shaft gear, according to the manual.

Did you normally start the bike with the kickstart?

Are you sure it's still locked up now that the clutch is disassembled, the kicker should rotate the inner part of the clutch which you should be able to watch?

It's always been kickstart only as long as I've had it.
Even with everything disassembled the kickstart won't move.

I thought you said the kicker moves if the clutch lever is pulled?
Being disassembled is like having the clutch lever pulled.

In that case, check the big nut in the center of the clutch. The pusher, which is like a mushroom shape, just pulls out. There is a ball bearing behind it which may fall out, so be aware.

Check that the big nut is tight and that the inner basket of the clutch doesn't move in and out.

As soon as I took my spring plate off, the kicker started rotating. As I tighten it down it locks the kickstart. Just the pressure of having all bolts and springs finger tight makes it 90% harder to rotate - 100% being immovable.. I took the pusher out AND the ball bearing out and inspected them. I'll post pics.

I can pull the pushrod out from the other side and its still locked up. (ball bearing is still in it I promise.)

The rod can come either way, but I think the ball bearing, if it's the right size, can only come out on the clutch side, not the sprocket side. That is how it is on many Kz's.

The kicker engages the first gear on the output shaft, and that first gear engages the first gear teeth on the input shaft (which is the shaft that the inner clutch basket is connected to). I wonder if something came loose that now allows the clutch basket to move and causes first gear to engage while another gear is engaged.

Does the inner basket move out or in when the pressure plate and springs are out?
When it's assembled, the springs are trying to pull the inner basket away from the motor.
Your clutch nut looks tight though.

Here are some pics of the in and out put shafts with all the gears and kick starter mechanism.

I my opinion your kick starter mechanism (gear on the shaft) locked your output shaft.
