interesting, nice photos.
I saw in another language a vdeo of "synchro diesel" I couldnlt make heads or tails of it. it sounded like a boxer...but definately a diesel. I thought they made one in the liquid cooled years anyway. that crank would go forever.
even a perkins snaps a counterbalanced four banger.
anyway, nice build. I thought sure I commented on this, so if you see like 3 or more posts from me saying the same thing...blame the geniuses behind it all. I seem to be deleted randomly.
I would grab that sale if I could.
