*grunch*

I think that despite the attractive pot odds K4s is too weak and does too poorly multiway for a call preflop here. Seems like a pretty clear fold to me.

I am not too sure about taking one off on the flop either, I would suspect my K outs are not clean and regard my total outs as about 3.

With the hand played as it was to the turn, your action was fine on this street.

I agree with the river check, and I think a turn CR would have been silly here. I think, seeing the K from the after-hand perspective, it seems like a grand idea, but most of them time your hand would have missed here.
