If there is a brief walkthrough of this, I couldn't find it. Do I need to take my oil pump apart (while I have the rest of the bike apart) and do any sort of maintenance? It seems like replacing o rings is popular, but I couldn't tell if that was only in response to leaks (which I don't have). Also, for the tube that connects to the screen, can I just use a piece of fuel line or something like that? Anything special needed there?
