What are the benefits of this mod over just ensuring proper squish or modifying the head (insert) to increase the compression?
This is a trick mostly used in forstrokes to increase the capacity, like boring out the cylinder. Whether you select to bore or to stroke (or both) would depend on how you want your engine to perform.

You would have to raise cylinder to bring the compression down to normal, often done by placing a spacer under the cylinder. But on a twostroke, a stroker crank would also lead to changes in the port timing, making it more difficult to just add a spacer.
