The casings are cast aluminium alloy.

Sounds bad. I've welded an aluminium crankcase before. If you intend to weld an area that was in oil, you have to clean it out really well. The piece that I did was a '65 Triumph primary cover. The crank sprocket came apart and blew through it on the track. They walked the track and found every piece. It was baked and hosed over a two week period to get the oil out. Aluminium absorbs oil kind of like a sponge. Anyhow, it took quite a while to put it back together but the oil-free aluminium welded like steel. They raced it the whole next season that I know of, trouble-free. Looked like Frankenstein's monster(hah!). Take yer time cleaning it and it should go fine. One caveat, though: If you're anywhere around the bore. throw it away.
