Hole in crank cases?

[Drezza]

I'm trying to get my crashed Fazer back on the road, the right side of the crank cases have cracked where the starter clutch cover bolt goes. Will it leak oil from the starter clutch area? If oil is not supplied to this area I guess I can just use something like JB weld?


Edit: you can see the cracked crankcases at the bottom left of the starter clutch cover.
