Yeah, and at the end of the day the average person doesn’t care to mess around with it. Just cheaper and easier to get a new cylinder. Now if it is a custom deal, or a rare engine that you can't get parts for, sure.

Me, personally, I would probably just bore the cylinder out, press in a steel sleeve, and machine out the port holes to match. Also a lot of work, sure, but work I can do at home, or have done by most machine shops.

Plus, a steel sleeve will last for ages to come.

I'd do the same as you, steel sleeve it at home and pin 'er in. Some people like to play though.

Where would you get the sleeve?
Most engine shops can order them from suppliers. They may require sizing before installing in the OD, and the cylinder itself gets bored to size for a tight interference fit, usually requiring the sleeve to be chilled and bore to be heated AND then pressed in. After that it would be bored for ID and the jug lightly decked. The tricky part with 2 strokes is the ports have to be done by hand. That creates some of its own challenges, obviously.
