Get it apart first, and even though it is simple, organize everything well as it comes apart. IIRC the Honda doesn't have a power valve, which makes it even easier to tear down. When you have the cylinder in your hand, look inside it. Any scratches that you can catch a fingernail on means it needs to be rebuilt. If an iron liner they might be able to bore it oversized. More likely it is nikasil lined, which requires a bore and replate.

Get it apart first. Try the hot oil trick and maybe rock it backwards in top gear too.

With a crank rebuild, You'll be in it about 6-700 bucks. The overall condition of the bike should guide your next move after you see the damage. Running but ratty examples are about that price already.
