That brings back memories, sitting on my bicycle in ba*****t listening to radio broadcast of race and hearing the engine rumble from across the knob!!
Thanks for that shot of the mini bike loudbang. When the weather finally got better during this covid thing I found many of my neighbours like myself owned vintage mini bikes and we started to ride them around the side streets around our neighbourhood together every now and then. The neighbours get a kick out of them zipping by in a parade. We got to be careful though as the cops in my area have no sense of humour and I don't think I can out run them on a three and a half horse motor.
