It was my first oil change on my bike!
On Part List, page 15, there is item 10 named Seat, oil filter spring: is that part the kind of big rubber grommet that is present on both sides of the oil filter element???
I ran my first season with a magnetic oil drain plug, there was some black stuff on it, I supposed it did its job to collect metal crap in my engine.
Is there some maintenance to do with the check valve enclosed into oil filter center bolt?
