Cleaning out storage came across another treasure I had forgotten about. (It was mixed in with some transmission parts in a crate) At first it was "WTH???" And then, in fuzzy memory I recall buying this in Canada. (BC, where the loonies roam)
So I had cleaned off the dust and grease and had it out, when celebrity list member came to town and a visit.
(Brittwit Dan from Kansas) So, I advised him to be careful, notify next of kin in case stacks of parts fell over onto him, and he got the tour. (I probably talked his ears off). He remarked "That is very interesting!" I believe that is the southern gentlemans way of saying "You are crazy!" But perhaps he really did think it was interesting. (He made that comment several times). But I at least enjoyed the visit, and he helped with a lot of BSA Knowledge and some info on one of my Goldstars that appears to have race history and my off roader BSA.
So, back to the head, The casting numbers are long gone, but perhaps the list collective has some input or opinions on this. The issue seems to be is this a period manifold, and was it intended for BSAs or something else? Someone welded into place clearly, And the welds bother me, However it is secure. I will check with Liquid penetrant, but they appear solid and without leakages or pinholes.
My instinct is to want to polish and smooth the welds so it looks less cobbled. As well as the rough casting marks on the intake. Other option is to radius and smooth the welds and rough areas and then do a water jet media blast and retexture the whole head and manifold for a stock-ish cast appearance and could tell some tall tales at the next bike show.
Anyone ever seen anything like this, or the manifold specifically??
I checked the ports and theres a good match to the intake ports, there is a slight step that would prevent reversion but nothing that will impede incoming air/fuel.
Not sure what I am doing with it yet, Static engine Artwork for display? Sell it in Satans Swap meet? Put it on some BSA project???
Input appreciated
