I swear I wrote a reply to this yesterday and I don’t see it so here it is again, got the bike added seafoam when that failed to help (a long shot). So then pulled carbs for complete tear down and rebuild, drained tank added vinegar for a couple weeks. Tried to make sure I flushed that all out. I’m pretty sure I put Rec fuel in there. Maybe not. I got my cans confused at some point. New fuel lines, new filters and here we are. I asked the owner if he ever put any kind of liner in the gas tank. I have not heard back yet. I’m gonna replace the fuel filter filters too as gas started to flow decently when I drained it and then it stopped, I blew up into it, and it started flowing again so something might be clogging up in there.
