My 1990 Tomos A3 Bullet has a gas tank that is part of the frame. It's a real mess with rust and I have been working on it for two weeks using evapo-rust, metal rescue, you name it. It has cleaned up a lot, but no matter how much I treat it and flush it, the rust particles keep coming.
I'm wondering if anyone has ever mounted a tank over the existing, integrated moped tank? Maybe added some tubing between the existing tank and the front of the seat post and then added a cafe style tank? I have attached a couple of images: one of my step through and one of a Tomos cafe style. The frames look similar except for the part where the tank is mounted.
