It’s a question that can’t be answered because the are so many things you don’t know, I should have explained when I said before won’t know till it’s apart
What affects whats found when the head is removed
Previous owners maintenance practices (tipping they weren’t good cause the top ends worn out)
How long was it ridden dusted, maybe that’s why he sold it? It’s worn the face of the valves so again I am tipping it won’t have done the chrome face of the rings or cross hatch any favors. That said I have seen people get away with it a few times could when pulled down it’s fine. (chops didn’t really need it at 6000km but we did it because it was apart and seemed silly not to. It could have happily run it but didnt)
You don’t know how many klms or hrs its done (can you believe the guy or previous owners?)
Then I could find that it has a lip in the bore and honing will give it to large a ring cap when standard rings are used and needs boring. Oversize piston and rings required then. Bestvwait till it’s apart I think
