A single crankcase V-Twin 2-stroke could possibly be made if both pistons were at TDC and firing at the same time, but it would be hard to balance and probably not that efficient.
Actually I think you'll find that with a two throw crankshaft to get both cylinders a TDC at the same time it will work fine, and be pretty smooth. The primary imbalance of one cylinder cancels out the secondary imbalance of the other and vise verse if it is a 90* v twin. Think Ducati, Yamaha and Suzuki twins, the Honda Shadow v twin had off set journals to give some character to the motor, HDs are just messed up balance wise.
the crank would have to have different strokes with higher piston speed on the rear cylinder to catch up. it wouldent flow right and would be very inefficient.
