Hi Con,

I haven't inquired again,but it should be available by now.

As far as I know, the S has a different crank, piston and rotary disc. It has a bit more power, quicker throttle up and smoother transition.

Again, only what I've heard:

Not sure what is different with the crank.

The piston is lighter and a different shape. Being lighter, it may give quicker throttle up and the different shape may give a different combustion burn giving a smoother transition.

The rotary disc has different timing, allowing more air through to the inlet giving more supercharging effect, which would give more power.

Once I get one, I will know for sure
