Why does the BMW K1200LT smoke on start up?

all of the BMW "k" engines will smoke on startup from time to time. It's due to the lay down engine configuration. The cylinders are parallel to the ground and arranged front to rear. So, the cylinder head runs fore and aft down the left side of the bike. When parked on the side stand or kick stand, a small amount of oil can push past the rings/valve seals and enter the combustion chamber. When the engine starts, this small amount of oil burns and smokes pretty bad for a few minutes. It may do it once a year or once a week. There is no pattern. The way to eliminate it is to use the center stand only. The k engine has done this since released in 1983. We say, the possibility of the engine doing this is relative to the number of people standing around your bike.
