Has anyone had to replace the radiator on their pig yet. I did the China Hat ISDE a couple a weeks ago and about 13 miles in I tried to split wood with my radiator. Somehow the radiator gave. I am only finding the fluidyne for $399 our there on the web. Or what do you know about repairing these. I punched a 1 inch hole in the very bottom left corner, not the coils.
