Ok I just got a tap and die kit. FYI, Harbor Freight has a sale right now, and I picked up a 40 piece metric and 40 piece SAE tap and die kits for $22. I ran it though the crank, and it worked, There is a thread right in the middle that not so good looking, but all after that they look brand new (which is where the nut should sit hopefully). So I will get a nut and see.
Now I have red locktite, but how much will I need to apply. I need to heat the case and freeze the bearing, I don't see how it will work, might just burn off.
I will be using 3 or so big c-clamps at the engine mounts to press the case back together. I will be using Permatex Ultra Grey to seal it.

I decided to listen to my girl, and go to this "craft" store with her. Its one of those girl stores. I found this material to cover my seat with.... ok she did, she told me to check it out :-) . Its marine grade vinyl stuff. Its super strong, and nice and thick. Its the same leather type material you see on boats for their seats. It only cost me $10 for a 3'x5' peice. Im having lots of luck with this bike so far :-)
