To be honest with you, the YS .45 two-stroke and the .63 to .70 four-strokes would be my choices. Especially the four-strokes. The four-strokes by YS are unmatchable by any two-stroke in the .40 to .52 displacement range. I'm not referring to just horsepower, but tractability also.

That is the thing I enjoy most about my YS engines is how
"tractable" they are...Very easy to manage power, smooth and consistent and always there for you without hesitation at any attitude...
I wonder how these Nova/Rossi engines are in that regard??
Have Fun...
