Well, there are no engine mounts in classic meaning, just couple overhangs with silent blocks on a engine housing and coresponding overhangs on a frame, with axle protruded through.
Although, speaking of front fork, you mentioned wobbling. Maybe those silent blocks (their rubber) are worned so you got this wobbling. While you are there, check silent blocks (or bearings) on this "engine mounts".
About vibrations. Are you sure that they are originating from the engine, not from the tuppeware?Ask me nothing - I DO NOT speak english. Really...

I suggest you do an oil change and this time measure what comes out. Drain it into a measuring cup and see what comes out in ml. A 1200ml capacity does not require you keep putting in 1200ml, as some of it clings inside the engine. You will always get less out then what went into a dry engine in the factory. In that you always put in less then what is capacity, once you see the difference then you know how much to put in for each change and it is never going to be 1200ml.
Also the front forks may have had their fluid congeal, unless they were totally disassembled and cleaned you would not want to be filling them to capacity.
If overfilled it will eventually come out, through the vent first and if over filled can do damage, the forks will lose fluid at the seals.
Back out some oil and clean it up the air box, That same model is made by Znen, its called a Roar 250, they do operate out of the same province. Znen exports a 250 version they only sell a 150 version in china though.

Thank you for the input guys!
Yesterday I checked the engine mounts and the rubber bushings in them - they're ok, not worn out, not cracked. Vibration feels like it's under the feet, where the floorboards are. And it is still there.
I did the valve clearances - they were not set according to the manual at all! All the gaps were much wider than what the manual suggests they should be. Both a pair of inlet valves and a pair of outlet valves had different clearances within a pair, which is, well, strange. On a side note - inlet valves are very easy to service; outlet valves are a pain in the butt to get to and to work on.
Changed oil, 1050ml went in, cleaned the filter. Will see what's next.

Been reading about CVT transmissions, since you have what is called speed related vibrations. The rollers move outward, which pushes the drive belt to a higher ratio. So you could check the rollers, belt and slide variator, since the vibration is occurring at a certain point in its range of movement.
Good Diagram.

Don't be suprised "if anything could be done there" is fitting of a new parts.
As I see, "scooterists" do that (mending transmission) preety often. Those parts are... "расходники".Ask me nothing - I DO NOT speak english. Really...

I'll see what can be done though. Like I said, I have a new clutch, pulley and rollers. I also have anew clutch bell. The belt is old though. Actually, at the moment I am pretty lazy to take that apart (yet, the natural curiosity in me begs to do so).
I put my bike on sale for 12K, hope some Chinese dude will be interested in having a big white "imported" scooter.

Can't argue with that!
Somehow I started to think what would be Steve's next purchase.
Pit-bike - checked
Cross - checked
Classic - checked
Commuter (blue Suzie) - checked
Hard-to-define-twin-cylinder - checked
Naked - checked
Scooter - checked
Did I missed something?
Let's place our bets.
I say - next could be a semiauto-clutch underbone.Ask me nothing - I DO NOT speak english. Really...
