I'm trying to get a 77 DT100 running for my sons friend...

I pulled the cylinder because it didnt seem like it had much compression. Piston rings are stuck and the sides are really brown/black.

Going to get a new piston and rings.

The bottom of the cylinder has an ink like stamp that says ".013".

Oversized/bored once before? I havent measured it yet. Wondering what the mark is however.
