I have some experience of having a crankcase welded - not a good experience unfortunately.
I had a Kwak 750 H2 that wouldn't change gear - absolutely solid on the lever. Had the engine out and apart to find that the crankcase had cracked around the gearbox area. A friend of mine who was a pretty experienced welder had a try, but every time he tried to weld a bit, the heat just distorted and cracked the cases elsewhere. BUT, the cases on that bike were a really crappy quality ally, very thin and easily prone to cracking (vibration used to crack them around the engine mounts - they were known for it.) I think maybe the Fazer would withstand welding on the cases a lot better? Not sure though... :\
