Re: Curious about the engine, :question:
I got the jug off and mine is still a regular 38mm stroke crank.
The jug has substantially better "as cast" transfers, but they still have that damn ridge! I'll be porting this one a bit more aggressively since it already has better ports and can use the mods better hopefully.
The bottom end does look a bit different around the transfer bulges with TONS of room for opening it up but no stroker crank, alas!
If more is better, then too much is just enough.
If you can't afford it, build it yourself.
