Head and barrel swap

I've never done it with the motor in the frame. I would try putting
the pistons/rings in the cylinders before installing the cylinders, but
those second circlips might be tough.

Suppose it all depends on your skills. I'm a shitty mechanic but I can
remove a SV motor in 1.5-2hrs by myself and the same to reinstall. So
I would rip the motor out and work on the bench if it was me. For a Gen2
the only "special" tools I had to get was a 19mm and 23mm socket.
