That would be the oil pump & oil filter.

Go to - your bike - Oil Pump
Remove cover # 2
Turn gear # 6 until the 2 large holes give you access to the screws behind the gear - remove the screws and the oil pump.

The oil filter works ** centrifugal force.
Any crud in the oil, is flung to the outside of cover # 11
Remove the cover and clean inside of it.
