Plus, with a 2 stroke you're counting on the crank seals to help maintain compression and they're a seriously wearable part. Not only that but the rings passing over ports will start to wear them quickly as the piston begins to slap. Not an issue with a 4 stroke.
The upside of a 2 stroke, as you know is that they're much lighter, less moving parts and much more power-per-displacement. I do miss all that power! As you remember, all you needed to so was clean up the ports and add an expansion chamber and it would make them monsters. :-)
