Thanks for the help and ideas. I found out that its not a Rupp "continental" but its actually a Rupp "Digger" Same bike but has a gas tank mounted on top.


I sent a wire brush down the pipes , actually a home made brush made with long lengths of welding wire with the ends bent about 5 feet long hooked to a drill. Very dangerous but it seemed to work. When I flipped the frame over I did not see any big rust particles come out (good sign) , but there was some black fine powder.

Seeing the bulge in tube it makes since that water got into it and froze. Glad that it is from water freezing and not just rusting out which would be worse,IMO. I spent a few minutes late last night massaging the bulge with a brass hammer to try and lay it down evenly. The metal is still pretty tuff but its moving, so I think the metal in these areas is still pretty good. Gonna try and get it weld up today , I will get some pics.
