Not honed on last top end = low comp?

Hey,
I had a 1994 RM125 (just sold it last week). I was sitting here lastnight and had a thought pop into my head. The bike had not been running for the last year due to low comp, which I did not know till about a month ago. What Im thinking is because I didnt hone the cylinder last time I did a topend (my friend talked me out of it.. I should have just got it done anyways), that the rings did not seat properly and it lost compression fast. There was only 6 hours on the topend before it quit on me.

It isnt really important now, but I was just wondering if anyone thinks this would be the problem, so I can help out the guy who bought it. Too bad I didnt think of it before I sold it.. ohwell cant go back now.

Thanks..

They were visable somewhat, but the cylinder didnt look like it was just honed. This is the kind of thing that makes you feel dumb lol, when I could have maybe fixed for probably 40$ and still have a bike instead of selling it for only 650. Ohwell.
