Someone, a machinist, needs to be making an alternative engine mount swap so a Harley could be bolted into the Mog.
Again, for a Harley motor to "bolt" in to the motor/trans adapter, it has to be an '06 or earlier. You would probably want a "B" motor which were only available in Softails and as crate motors. They have the smoother counterbalance shafts internally.
As also said, the mounting of the motor to the frame would be a complete new mounting system.
