Well Rick, welcome to ATM. This is an awsome site.

Umm...I'm at a loss as to what you are asking. Do you mean the oil system and if so at which point?
Also, where is Welland?

Rick, I'm looking at a 83-86 XL600R service manual.
Looking at the front, directly at the exhaust ports, the 2 oil lines come out of the lower left engine case. The line on the left side, highest port, is the fat line (long) and is the "outlet" line which leads to the top of the XL frame.
The line to the right side, lowest port is the "inlet" line (short) to the oil pump and comes out the bottom of the front down tube of the frame.

I may be able to scan the diagram and send it to you but I have a little learning to do. Hope this helps.
