Pictures would be helpful. Do you have a photobucket or flickr account? If you can provide a link to a good picture I'll help you get it into your post.
Without seeing it, though, I think the following is what I'd do if it were mine:
1) Stop the crack from propagating with a small hole at the end of the crack, plugged with JB Weld.
2) Use a rubber washer under the drain bolt to reduce the torque used on the drain bolt. I might, under the right circumstances, consider bonding a plug in place with a smaller drain bolt in the center of the bonded plug. That would reduce the wear and tear on the case and the repeated flexing of the crack. Under the really, really right circumstances I might consider installing an oversize plug, bonded with a drain in the center. The reason for that is that a larger bolt can induce less stress on the threaded hole than a smaller bolt will.
3) Park it over a diaper.
Often the only real fix is a new case. JB Weld as a patch can work in some cases, but the crack goes through the gasket sealing surface. A JB Weld patch job may turn out to be a lot of work for little results and may foul the case preventing a later weld repair.
Welding can work, and can be done with the engine in the bike, but the crack goes through the sealing surface. Depending on where the crack is, welding can warp the cases resulting in as bad an oil leak as the crack caused.
The oil leak from cracks like this are usually minor and can be lived with. They don't come anywhere near approaching British car standards ;^). I'd be leery of riding this bike to Tierra del Fuego, but for local riding it should be fine.
A good picture would really help people come up with a workable solution.
Oh, and welcome to the forum - sorry it has to be under such circumstances.
