I am not so sure that the 'acid' dipping is actually acid but is something like dichloromethane (methylene chloride) / de-carbonizing agent mixture that removes stubborn carbon deposited in the 'pits' of the casting too.
I think any kind of real 'acid' would be a most definite no-no, however mild it is..... but what I described above should be perfectly acceptable.

Ok checking other images (which I probably should have done first) it does look like they are supposed to be there. They are just so uneven they don't look like they are meant to be.

Aren't they going the other way? Just crankcase air vents leading to the air plenum and vent hose on top of engine.
Most engines vent out from highest point to avoid as much as possible the risk of pushing oil out under "ahem" extreme use. :)
The cover over the cam chain acts as a baffle to prevent oil flinging too.

Been falling behind on posting progress, but with all the time given back to me this Christmas I hope to make some headway and will post up some pics (and some questions no doubt).
I got the frame, tank and seat back from LV customs, I'm sure it wont be to everyone's taste, but I'm very happy with it.
