Thanks for the recommendation.
I always worked under the impression that the oil film stays on engine parts for over a year and more.
My HP2 is not used during winter for quite a few months. I never really bothered that much, never had an issue. As above, I don't start it when it's not in use as I wouldn't be able to ride it around and bring to temperature.
The only time I started it (couple of winters ago) briefly in the garage for a couple of minutes, when then I actually started it for the first time for a ride, a month or two later, I had a brief puff from the exhaust, clearly signifying some condensation got in. Probably/hopefully just in the exhaust.
I've pulled engines apart that have sat for YEARS and everything was still oily. But that oil is probably oxidised. I'm still not overly worried though.
If I'm not riding a bike for the winter, I just leave it alone with the battery disconnected. If carbed I'll drain them. E5 will last just fine for a long winter before it does any harm. E10 may not.
As you say, there is plenty of oil hanging around and no damage will be done. Especially with these wonderful modern oils we're all using.
I start it up without any special procedure in the spring. I let it get nice and warm on it's own. Then check everything is in order.
It does depend on the bike though. But I presume were talking about fairly modern Beemers here.
