KTM 640LC4 engine

The old KTM640 LC4 engine (not the new 690 LC4), with a Keihin FCR41 flatslide carb, as used on my own project. Created for engineering, not rendering, by measuring on the actual parts, so all interfaces, including chain offset, are 100 % true. But no internals, and some minor details are left out. Weight as shown is 42 kg dry.
