I am changing the oil myself for the first time on the Monster S4 (usually have it done at the shop while in for other things). I assume the oil screen/mesh bolt is the one below the sight glass.
I checked the FAQ (it was written for a 2-valve) and stated it was a 21mm bolt but on the 916 motor in the S4 it is an allen head. The largest allen socket I have is a 10mm and it is too small. Anyone know what size it is before I go buy several?
