First ideas about tanks and seat shapes, exhaust lines, in various materials. All that finally resumed in one conclusion: the engine will fit in the frame , but it will be a very close fit, imposing many chassis modifications. These mods were actually very impressive at the moment, being a non return way for the Laverda frame,and finally almost invisible once the bike finished, fortunately.
Once the empty engine inserted in the frame, with the separate gearbox in a higher position and the final transmission in line with the rear sprocket, I feel much better: the project may go on without too many worries, only time, patience ... and some cash.
