No doubt easier but since a smaller engine has a relatively larger
heat loss to the cylinder walls - compared to a larger engine - it
makes less sence for a high compression engine.
The reason I'm looking for a 500cc is exactly that. The 50cc we have
been working on has very significant heat losses. Areas (heat transfer
areas) grow with the square of the engine size - volumes (combustion
volume) increase with the cube of the engine size. Larger engine =
smaller heat losses / cc.
