Most all know how to do it, and have basically explained how, but you insist there's another way.
Actually there is. If you Google search, it was mentioned in a thread in the last five or so years.
I refuse to go into detail as you have flipflopped about selling just like polititions do on things. And I beleive you intend on selling it after applying a Presidential Solution. The "repair" I refer to was done on a riding trip of considerable distance and was repaired properly later, which I know you have no intention of doing, you Demo.
If you have no faith in your mechanical abilities or how to follow a repair manual, you need another hobby. There is no engine easier than a Banshee to split the cases on.
One hint I will give is clean case mating surface with laquer thinner, spread 3Bond/Yammabond with an acid brush, nice even coat, don't goop it into threaded hoes. (pun intended)
