Gas cap for the low budget

[562bisikel]

I just finished customizing this jesse james bicycle tank needed to put a new tunnel to fit over my top bar I still needed to weld in a bung of some sort but being the impatient person I am I came up with this for the time being used a compression plug with a ss washer and acorn nut for appearance seems to work great pics arent the best sorry

That's thinking outside the box, I like. How is it vented?

I like that a lot! now I know what to use on that Moped tank From Ebay that I can't find a cap for:~) Think I will use a small skull lisense plate nut on the stud.
