Started up my 82 GL500 for the first time in a questionable amount of years and noticed some (maybe) white smoke. I've searched the interwebs but have had a hard time finding an exact explanation with images of exhaust smoke and what it means, to compare to.

It has brand new oil + filter.
Clean and rebuilt carbs.
Distilled water + coolant cleaner for a flush.
And no airbox (filter on the way, didn't have one).

Any input?

Also when I changed the oil it wasn't milky or clumpy. Beyond the tiny bit that's to be expected when an engine sits for years on end.

Or so I was told... (This ^ was all that was discolored)

It's not unusual to get smoke after a long layup. It should clear up after a bit. I didn't see much in your video clip.
If you're concerned that you might be burning coolant, look for bubbles in the coolant reservoir after the thermostat opens. Any combustion gasses forced into the cooling system will end up there.

I put a shot of Mystery Oil in each cylinder, cranked with plugs out and let sit over night before first start in the morning. I had about 3 minutes of white smoke as the oil burnt up.
