Upon lift, the exhaust [in the pipe] kind of hangs and fills with burnt oil from worn guides. You leave the light and it clears it out. This means a valve guide might need changing, or a band-aid fix might be to change out a cracked guide seal that is so many years old with this year say.

It can also be a clogged check valve in the vent tubes between the Cylinder Heads. S&S has the blow back from the breather connected to the rear jug. Allowing the "puked oil" to be dumped into the rear cylinder and burned off. My K9 had this issue recently.
