Ok don't laugh. Is it hard to add a speedo to a Bravo that never came with one? I am not really interested in the speed but more the mileage we put on the sled. It will also help to keep track of how many miles per tank of gas without stopping to looking at the site tube on the side of the machine. Also does anyone know how many km or miles per tank of gas on a 1990 Bravo short track not a long track.
