I absolutely love reading ADV forums.
brought to me the picture of the o-ring and tube between case and oil pump. I couldn't remember if my bike had had that part! quoting myself on the other thread:
"this thread just saved my butt, I'm thinking. I had reassembled my XR600 after buying it as a basket case, and got to thinking: did I see that little oil pump o-ring and metal tube? I remembered the o-ring, but not the tube. I haven't run the bike for more than 10 minutes, because of a few other issues, so today I pulled the side cover off. Sure enough! NO tube! PO must have lost it upon disassembly, and since I bought it literally in a basket (ok, milk crate and cardboard boxes) AND that tube isn't magnetic so it didn't stick to the magnet tray he'd given me with all the bolts, I was clueless as to its existence. Whew... I pulled one out of my parts bike engine and installed... Thank you! good pictures and detailed information."
yep. thanks ADV. "I don't want a pickle, I just want to ride on my motorsickle" -Arlo Guthrie
