That's basically what I have been saying.
Larger cylinders run more efficiently than smaller ones, as the surface area (cylinder walls) of a smaller engine are proportionally much larger than on a larger engine.
I mean to say, a single 250 is more efficient than a twin 250 (with 2x125cc), and more efficient than a 4 cylinder 63cc per cylinder.
Also more efficient than a 63cc at speeds where the larger engine isn't lugging.

Despite that the Honda 50cc racers were twins ....and remarkably successful.
