Need to help out a fellow rider.(UPDATE! post #13) I met an old, skinny tattooed rider a few months back and from what I can tell he's homeless. He has a phone but that’s it…….no access to the internet etc. I’ve been helping him with parts here and there but he says his engine is on its last legs and asked me to look into getting one for him. Any suggestion on where to buy just an engine and carb would be appreciated. His bike is his only transportation so I want to move on this….really nice old dude. Oh, we’re in CA.
