I have a Honda  VT1100T, a Shadow Tourer. I do a lot of my riding out west. I can get 120 miles out of this tank before I have to go on reserve. I would like to put a larger tank on this bike. Someone on the west coast converts Harley tanks for Shadows, and I understand they are quite costly, butI would like to check it out. Anyone around here have any idea where I might start looking? Any help would be appreciated.
