After sandblasting the frame and other parts it's time for powder coating: after 3 days, phone ring "frame is done..."
In the meantime, the engine was disassembled and we made the diagnosis and parts list what to buy...new pistons with piston rings, all bearings and oil seals in and around the engine, main bearings, big end bearings, timing chain, push rods, tappets and a new cluch...
The gearbox is also taken to peaces; replaced all bearings and oil seals...
