If I may,
to possibly solve the oil filter spill issue,
Why don't you slightly tilt the bike to the left side so the remaining oil in the engine can pour into the oil filter, and since its tilted to the left, the oil should generally stay in the filter and not all over the bike.
If this is a crazy suggestion i do appologize lol .. I will be picking up my new 2013 636 in January, I've seen where the filter is on the bike (same as 2012), so I'm not trying to figure out ways I can keep the oil in the filter or bike lol
