Default RE: 4-STROKE engine is equivelent to what 2-stroke

ORIGINAL: Richard L.

A normally aspirated 120 4-stroke is equivalent to a 91 2-stroke. The YS 120 4-stroke is equivalent to a 120 2-stroke, maybe even slightly more powerful.
A Rossi 91 2 Stroke engine will have more power than a YS 120 4 Stroke.
