Wow are those webs actually cracked?

The pitting on the journal, on the scale of bad things for a crank, how high does that rank? Would it interfere with the bearing seeing that it doesn't necessarily protrude, just a tiny hole?

I'm afraid so  :-\, not sure if this is a result of the engine being run previously out of balance......but wouldn't have thought so.
I don't have the crank back yet its still at BDK and I asked for the photos from James.

the mark on the big end pin looks like a surface imperfection and I would not use it like this as it is likely for the big end rollers to pick up on it.

I'm back for a visit again at Christmas so I'd like the crank back by then so I can reassemble the engine.

Crank parts are finally with James at BDK so should be all repaired by end of next week ready for reassembly when I visit at Christmas.

Thanks go out to Edd for all his help and perseverance with his  (-P) (-P)

Not sure if we are doing Spa next year, there was talk of Misano for a track day................
