Getting ready for an oil change on my 2008 990 Adv S. Warmed up the bike and took everything off... But there turned out to be a lot of stuff to remove (crash guard, skid plate, tank, fairing) - so two hours in, the oil is probably cold and I have to leave to go do something else. How can I warm up the engine oil before I drain it? Can I run it with only one tank connected? Or am I resigned to a cold oil change?
