Best possible scenario for seized engine?

[Ariel Balter]

NB: I'm not an engine person.

My son has a 1994 yfs200. The engine seized. He removed the top end (cylinder). Nothing seems damaged there. The piston won't move and it won't crank over.

The worst-case scenario is it needs a complete engine rebuild. ~$600 just for the kit--for starters.

What is the best-case scenario?

Looking for some hope here!

So you pulled head cylinder? And piston does not move on rod? And or rod doesn't move on crank?
Purple coloring at rod end or crank end
If that's the case you need to figure out why.
Lack of oil?
Airleaks causing lean condition/ wrong jetting?

You dont want to have the same failure twice.
