cracked crankcase

[cb750amen]

in replacing the gaskets in my k3 750 i noticed a small crack in the crankcase . can this be repaired or do i need to shop for a new one?   how bad of an idea would it be to assemble it and ride?

Looks like a casting mark but if it is cracked, repair it. Lumiweld (i think thats what it is) is a low heat compound that works very well on aluminum.
