I thought there was a baffle in the tank until i got a flashlight. I pulled this out of tank. The rest of tank looks similar.
Liner Side(is that a stalagmite or a stalactite?)

Tank Side (you can see the rust is pulled off)

Overall the bike is in ok condition, but i wonder what else i might find from the PO. I am going to order the POR 15 tank repair. I am counting on their stripper taking care of all the old liner. I hope that I won't find any pinholes when redo the lining. This project keeps getting interesting.
