every boxer does it if parked on the side stand - a little bit of oil stays in the left pot, then, when the piston rings are cold, it slips past into the combustion chamber and burns off

on oilheads like R1150GS, BMW went from 10w/40 oil to thicker 20w/50 to reduce oil consumption.

Yes Wessie you are correct. My R1150RS used to do it so I used to put a wooden block under the side stand to bring the bike up to near vertical. Problem solved. I do the same with the 1200RS and don't have a problem.

And now we complain about the R/RS1200 side stand tilting the bike too upright. Good job BMW.

You cut down on the startup smoke problem.

I rather the occasional smoke than the damned bike falling over ...

Had my bike for over 4 years / 40k miles and it only blew smoke maybe 3 times. I park on the side stand all the time except for if I am working on the boke. Don't worry about it. It smokes occasionally ... part of the nature of the beast, and is called character.

Some say that shutting the engine down after putting the bike on the sides stand causes this. Shutting it down then leaning it over on the side stand may be the trick. I honestly do not know. This issue has been discussed for at least 3 decades. My RS (and all my previous K and R) have done it once in a while. I do not give it a second thought.

Nope. I always put down the side stand with the bike on, unweight the bike so the suspension is uncompressed and then turn the bike off. No smoke from my bike. Like you I don't give this transient phenomenon a second thought.
