One last thing, piston rings in correct order and orientation? These are Suzuki ring sets, and they aren't like the Honda ones, so I'm not sure what order to put them in

What direction is the angle on the middle ring?  Sometimes the upper and lower ring (or upper and lower lip) on an oil ring is an angle similar to the middle ring in the pic.

this is what baffles me, I have 3 sets of rings, two aftermarket and 1 suzuki.. none of the rings are tapered

*EDIT:

ok it looks like according to this: https://www.manualslib.com/manual/1076648/Suzuki-Gs850g.html?page=83#manual
that I have mine backwards. either the taper is so small that I cannot discern it, or the ring isn't tapered, which concerns me a little - but both rings have the "r" so I'll just face that up"

The taper is too small to see.
Any numbers or markings go up. Top ring is light grey on outside edge.If you've had motor running you may see a faint 'shiny' line at bottom edge of middle ring (or top if it was upside down) Just looked at pic, you have top and middle rings in wrong places The 'chrome face' of top ring is clearly visible.All Japanese manufacturers have used very similar lay out since at least mid 1960's
I only 'recently' found out the various letters used are not what I was told40+ yrs ago but are the various piston ring manufacturers (Riko is the only one I remember at present, they stamp an 'R' on top of stock size rings) You can also get S, N, A, O (and maybe others?)

Thanks, I got it now :)

Everything back together correctly and just pending my final part (stupid top tensioner bracket) will literally be starting the engine the day of the bike show. Ugh

That looks better.  8) You have fitted all the circlips?

Lots of progress made tonight. Still a ways to go, wiring, startup, tuning, timing, exhaust. But I am very excited about where I'm at now.

Also, a look at the micro tacho that's mounted under the tank.

Oh, and why not the project that's waiting for "yatagarasu" to be done so she can get some attention.  82 BMW R65LS

You'll probably get pissed off with tach in that position pretty quick. Beemer is great bike to work on. there were plenty of 'Endurance racers' around back then (although mainly 750 & 1000) so all the 'work' on what needs doing to 'CAFE' it has been done
