It took more than a second look for me. My eyes went right to the coil. I’m thinking, that is odd. A Quad with only a single coil. When I copied the picture and expanded it to see the coil wiring better, I realized it looks more like a Speedster. As Harry knows sooooo much more about this stuff than I do, it could be a special motor, till he said it wasn’t.
A "Boathouse Repair" is one thats done without having tools or the skills to do it properly.
