You evidentally have not come across the manual for the M50 yet. Copronymous was nice enough to find and post the online M50 factory service manual. Save the site as it has lots of valuable information. For your oil change turn to page 27-its section 2-11

Side note-According to your sig, the bike is a 2006, im really hoping you have had the oil changed before, but if a dealer did it that filter is gonna be TIGHT. Dont be surprised if it doesnt just come off, you will have to use a filter wrench, stab it with a screwdriver, or some other method to get that filter off. Get a K&N oil filter #KN-138 I do believe, has a nice nut welded on end of filter for easy removal. Also the factory filter has a special oil filter wrench you can use if you get the special filter removal tool. The filter does not need to be on that tight, snug it down by hand and that should be all you need
