I was doing a head gasket replacement onnmy 86 Kawasaki ninja gpz1000 and I while cleaning the gunk off the top of the block I noticed a small gap/crack in between two cylinders (Pictures are linked below).
It doesn't go deep, and I don't think it would have an effect in performance or anything since it isn't near any place where fluid could get in, but it wasn't like this between any other cylindera ans I wanted another opinion. Thanks for any help!
