PS: I think you are the first here to use the Morini, I can't wait to hear how it go's. And a good looking idea.
I would go with something like a 47-49. I 36-40 will make you lose a lot of low end but that bike will be able to hit 50+mph considering the 47 topped out at 45+. I tried to take a video of the italian stallion but I left the camera on and it drained the battery
You should call Dean @ Pipelyne he could set you up with the motor mounts and pipe.
It's going to be one sweet project when its done.
