I'm wondering what the blue arrow is pointing to? It was years since I took the bike apart and my Clymer doesn't give any guidance. I guess a tube should be connected since the hole is spitting out a little oil. But what should I connect it to?
I also wonder if I need to connect the carburetor drain tubes to the carburetor, or if I can leave it as it is. Maybe this is basic knowledge, but I have not required it yet. As you can see I have switched to cone filters. The build is, except for this, complete and the bike runs good, but I have only driven it one mile to test everything.
