Well bike didn't run very well starves for fuel. I diagnosed the problem and its some sort of black unidentified substance almost like rust converter. That's all I can come up with that makes sense atleast I have heard of this sort of thing happening. So my?  Is any suggestions on how to clean it out. And im sad now because im sure my freshly cleaned worked so hard carbs are filled with this stuff. O and any. Ideas or can direct me to a thread on fuel line routing.

Wow! You really need to be looking for some Navy Seals to hunt down the Previous Owner (PO) and deep 6 em... Your carbs should clean out properly as long as you don't leave that $#@^ sit for too long. And you have some kind of filter between the tank and carbs.
