It's probably best that you take off your fairings otherwise you'll have a nice mess on your hands. Nothing worse than oil settling in your fairing lowers then making its way out and onto the road for your rear wheel to run over! As for the crush ring, that's there for a reason, just be sure not to over-tighten it. Also, unless you're taking off the heat-exchanger that the oil filter is attached to, you'll need less than 4 quarts, so mind the oil glass! Put in the first three quarts without worry, when you get to #4, only use about half of it, let the bike set for five minutes and check the oil glass - add according.
