Ouch looks like it's engine replacement time. That hole is catastrophic if you have the piece, and it is whole not broken up into many pieces it might be able to be tig welded back together. Good luck.

It's time for a new bike. In all seriousness that motorcycle engine is toast. And would cost more to repaire than the bike will ever be worth. Did the previous owner sell it to you like that??
