Just wondered how many are aware of this (#4) oil filter screen? Pretty many of the honda 4 stroke motors have them, not sure about other makes. I'll bet alot don't even know it exists . http://houseofmotorcycles.bikebandit.com/partsbandit/assets/schematics/Honda/HJ360037.gif Newer and older L's & R's have them. Can't recall if manuals tell you to ever clean them or not?
