Twitch... thanks. I saw you mention these guys in a previous thread and checked for dealers. As you mentioned there are none around here and time is of the essence.... I have about a month to wrap up all the "winter" projects in time for racing season... I intend to add more robust venting capability to prevent further occurrences but at this point (until I drop the tank and inspect it) I'm still just speculating what is going on... I'll make some calls around here to see if I can find a shop willing to take it on...

My engine guy knew a shop near his that does bike tanks but this one is too big for them in that it doesn't fit in their acid washer... depending what I find when I get it out, I'll probably try to wash it real good and make some calls to some of the other shops around here.
