Probably ever since we bought the polycarbonate windscreen for the 78 Intruder we have had sort of a love-hate relationship with it. It was always pretty floppy and little by little started to break down. First it cracked on the sides and we responded with some reflectors and some additional reinforcement. Then there was a small accident where a 2x4 got dropped on it - that is the why there is a stripe of packing tape down the middle. Finally I decided to just make a new windscreen. I am thinking that we should be in good shape for a while and should not need any more packing tape.
