So i've been scouring the net trying to find a cool used vintage motorcycle tank or moped tank to use with my moped. So far no luck, as i'm not ready to spend too much until i'm happy with the quality of my build. I was scouring ebay, i'm sure some of you are familiar with the "boy go fast" store on there. They have a straight style underbar tank (which in my opinion looks like it would look terrible, but if someone can tell me otherwise i'm all for it) and I also saw a rear mounting tank. The reason this store caught my attention was because they seem to offer 2L 3L and 4L tanks, I think the stock kits come with 2L....does anyone know if the bigger tanks will hang lower on the frame and thus achieve the "cool factor" the motorcycle tanks have, or do you think they'll just be wider on the bike?
