Looks like they are running a dry clutch.



I can't imagine that hunk of metal under the seat is a raditor. It doesn't look like it has any cooling fins and it's in a location that won't get much ventaliation.



I think rob is right on. Probably telemetry or computer for the engine.

I think you got a good point.



Not that I am an engine builder either but it would make sense to me that anytime you have an odd number of cylinders in a V configuration the cylinder sizes will vary to balance the engine.
