I'm almost wondering if you are getting blow by thru the rings which is pressurizing the crank case and forcing the oil to come out the valve cover. May have to do a compression and leak down test to tell for sure if it could be the rings, or I may be way off, just what came to mind after reading the issues. Shop may not have been able to duplicate if they did not take it for a ride and only looked at it in the shop. I'd expect the scoot to smoke like a chimney if oil was passing the rings. How much oil is left in the crank case after this happens ? Only if oil was getting into the combustion chamber, but if the blow by is back into the motor there would be no smoking, it would in turn just be letting the compression leak past the rings and basically prime the crank case, which in turn would cause it to spit oil. Have seen this happen on a car motor don't know if that could happen on one of the scooter motors, but heck anything is possible.

And are you sure one isn't for the exhaust port on the head to header pipe?

Going to need a multi-meter and start following the wires from the battery, did you make sure the ground is hooked up and not broken that could cause the issue as well. Best way would be to start from the battery trace it to where it goes, which may not be easy with the harness wrapped, when you find the end use the option to check continuity and make sure there isn't a break in the wire somewhere. I have seen where on the outside a wire looks perfect but was broken inside the sleeve, so would not allow power to flow.

Well if you are looking to have spares in case of issues I would get the following, new drive belt, cdi, coil, a jet kit for tuning the carb for when weather changes, (unless efi then don't have to worry bout carb), new sliders or rollers for the variator, if not a spare variator as well, and then of course some of the items you may need all the time, little tool kit to keep with scoot, a couple quarts of motor oil and some gear oil, just so you don't have to travel to get when time to do general maintenance. I am sure I'm missing something but is a start.

I may be totally off but when I watched the video, and where it growls and dies, to me it almost sounds like it is soft seizing, and then causing the motor to die out. I do not know anything about 2 stroke motors, but wondering if when you took the oil pump out, if it lubes anything other than injecting oil into the carb. Reason I am thinking this is I had let the oil get too low in my 150cc 4 stroke (had an oil leak and wasn't checking regularly) came to a stop at a light and the motor bogged down and died, would fire right back up but then when I tried to move would die again, pushed the last block to work checked and filled the oil and the problem went away. Again not sure if this could be the issue with the 2 stroke just thought would throw my 2 cents in.

Here is a current side pic of my scooter, will be sanding and painting in the next couple weeks. Going to be flat black with bright red stripes, just not sure how I want to do the stripes yet.

Use one of the banners at the top as far as where to get the kit, all tried and tested vendors by members on this site. As for what size I couldn't say never done a bbk

If it has a 10" tire is a short case if has a 12" or 13" tire is a long case, at least that is what I have been seeing when I was looking for a new motor for my scooter.

May be wrong but it might go to the ignition switch to sense voltage. I had a new pink wire on a new r/r I got and that's where it went. Mine is an ac system so don't know if it would be the same.

Check your bearings make sure any spacers are there,installed correctly. There have been many ideas of what it could be, try some may not be it, but won't lose anything but time, but one of them may fix it and then you will be good.

If the solenoid is clicking it probably isn't bad may be a bad starter. If it has a kick starter and you try to kick it over, does the motor turn over, or is it seized, if it turns over I would pull the starter and then try to start and see if the starter turns over out of the motor. If the motor is not seized and the starter will crank out of the scooter may be a weak starter, that doesn't have enough to turn the motor under compression.
edit: just noticed you said it had a new starter, however I would still try that after jumping the solenoid to see if it is bad even tho you are hearing the click, may not be allowing enough juice to go to the starter to turn it.

Just remembered, when you put the front on did you remove the front caliper or leave attached? I had left mine on and it caused it to bind up removed the caliper put back on and fixed it. Don't know if that could cause your issue, but a thought.

On the center stand if you wiggle the tire does it move, may be bearings. Can't think of much else that could cause that unless the rim had gotten bent, or may must need to be balanced, alot will day they don't need it, mine didn't put new tires on about 500 miles ago, and have had no problems with any wobble.
