I got bored and decided to make the bsr a little more exciting.Here a picture there is avideo to come. It has 4 in casters that soon enough will have to be replaced. Before buikding the new addition we were over at the high school across the street see how fast we could get it going and a cop came over i asked him if he wanted to ride and before he could give me any grief i ask him if he would radar me. He was cool about it backed up to the end of the parking lot and clocked me after a couple of laps he took off. It was pretty sweet.
