Never have. Did the manuals used or still have something about dumping oil for long term storage? First heard about it for sleds. Not saying it doesn't do some good. But i have made it this long. Not that you can't improve.
You are not supposed to start a vehicle, without letting it get hot. Skidoo now tells people, I am told, to start in the summer, and might even have indication when you can turn off. I do think about a truck I had that the AC was bad, and needed something fixed, so parked it for summer. Started leaking in fall.
I worry more about seals and gaskets, but I have nothing to back that up

Engine fogging is typically for long term storage and preservation, and is also very common with seasonal storage of marine engines, especially 2 stroke outboards.
I have performed long term storage on giant engines both running, or just in crates, so there are a few methods.
I assume you are talking about fogging your Harley engine. Is this for long term storage? You can totally use Marine Fogging Oil like the Sta-Bil stuff, and just remove the air filter and fog it through intake at an idle, it will gasp and choke, and then you just shut it down while doing it.

we pickled our large drivers with a pickling additive to the oil and then blanked off the intakes and exhausts. sometimes they stayed this way for years before we had a need for them or moved them to another location. when coming back online, we warmed the driver up to temp and ran unloaded for awhile and changed the oil and filters.

I don't fog, but my winter storage routine includes squirting some oil in plug holes & manually spinning tire to lube cyls...pretty easy w/ bike on jack. Probably not necessary, but it's fun smoking up the street on 1st spring start.

While I have always been against starting for short burtst, I have wondered about starting and letting them get good and hot. Had a truck daily 200 miles, ac went out and need a repair. So it sat over summer. It was blowing gas, and losing coolant when I started it.
I have heard skidoo now says to start in the summer and let come up to temp. The question to me is how hot to get moisture out of oil?

You get the moisture out of the oil by running so it gets hot enough to burn off any water. Not just idling, but getting out and riding/driving it for at least 20 minutes.

If you parked it after a long ride. Would letting it run until hot, create a lot of moisture??? I dunno. I can see the value in lubing up seals and gaskets, but not sure it is worth it. With my bikes I try to get them out for one last decent and one first good ride, and not letting them too too long.
