Do you know how far you can practically close the gibberish timing? (Ha! Spellchecker error, but I'll leave it in for giggles).

The one I saw. Mechanically, it can be completely closed. Practibly, it can be used like a carburetor slide from idle to fully wide open. It also could be positioned to tune out negative waves in the inlet tract. It did not open linearly with rpm. But moved in and out as required. Anyway that is how I remember it from when it was up on the dyno. Since then there has been an even clever double sided setup.

You have seen this Dave, but here again to view

New rules allowing for water cooling, perhaps the supercharged 150 twin might happen after all.
Having a lot if FZR 250 parts laying around, suddenly the price is right.

Birth of two water cooled twin port AG cylinders, I hope.
