    Does this valve look ok to you?

    So I had a melt down in my r69s, lean carb + advanced timing + who knows what. Got the new pistons from vech, bores done, so I'm looking at top end stuff now. The chamber looks ok, scraped a little melted piston from the inside, but it should be ok. I'm going to pit some pics, so if you all think things are toast, let me know. Thanks!

    Can't tell.

    Look straight at the side of the head of the valve and measure the margin (width of the edge). I don't know the spec but it ought to be a clean square edge.

    Then, look at that exhaust seat. I note the intake remains shiny as expected but the exhust seat appears to be a little knarly but I can't tell for sure.

    Here's a better pic of the exhaust valve seat

    Here's a better pic from a "real" camera of the valve seat.
