Didn't they do basically the same thing with the Supermono?

Hi Steve

Wasn't the second throw on the supermono a balance device?

Either way, I just like to see something a bit different. I've just looked at the spec for a supermono. 60 hp but 121kg! Blimey, light or what.

Maybe joolz can fill us in on the technicalities of the v-one blown single above.

Yeah, I think you may be right there.  They were selling some road legal Supermono replicas a few years ago, a snip at £30K + !!!

The penny has dropped!

What was puzzling me was that the "pump" piston is the same displacement as the combustion piston. So it wouldn't seem to do much supercharging. And how did it pressurise the receiver?

The answer is obvious (eventually!)

The combustion cylinder is a four stroke, needing filling only once every 2 revs. The pump can pump its displacement (sorry madam) every rev. Hey presto, pressure builds up.

Next question. How does the phasing affect the pulses?
