In early 2005 I decided to rebuild my old 47 U model. Back in 89 the bike seemed to be loosing power so I popped off the iron heads to install a set of Aluminum ones. When I had a look in the holes I saw what the problem was, a nice little chunck missing from the rear piston. I yanked out the engine and off it went into the corner. I ended up steeling the chasis and using it for my 47 knuckle for about 13 years. When the knuckle was ready for a rebuild I decided to re-shuffle and get the Flatty back together with the original chasis it came in. Here are some pictures from its latest rebuild from 2006.
