I just completed a oil change on my speciale. It can indeed get messy but if your not in a rush, let the oil drain out completely and when removing the oil filter cover prepare for a "little" spillage but not too much.Take it into the dealer if you can. I just finished after more than a few hours, and it was absolutely miserable. The dealer couldn’t get me in for a month and a half, so I decided to do this on my own. There are three bolts that you undo to pull the cap to get to the filter. Thread three larger bolts into the cap an pull hard. It pops and dumps oil everywhere, swap the filter, o rings, install, and torque. Don’t forget the plug washer.
There are recalls to do plus they can clear the service light. If you can take it into the dealer, do it.
Well if you keep threading the larger bolts it slowly pulls the cap off.
