Left a thread earlier, decided to get pics of this and see what you all thought.

1989 Force 125 compression of cyl 1,2 & 4 are @ 140 + / - cyl 3 is at 35 Pics show why, cyl wall doesn't feel scored at all, but if you look down the cylinder at the ports, there seems to be some scarring inside the port area, but don't feel any on the wall itself, don't know what is below piston yet, (first time taking apart motor, going slow, making labels, and taking lot's of pictures).

Any ideas what my chances are going to be just replacing the damages cylinder and rings? or am I just dreaming and should re-bore and replace all. Previous owner said top end was done 3 yrs ago.
