i don't know enough to let any trade secrets out, so probably mostly stating the obvious below, but from what i understand
short stroke 750, long rods/short deck pistons
custom CNC machined crank cases - there are pics on this forum somewhere, i think Jim Comstock bought a set.
Head, full auto but they bought one with minimal machining and did their own porting etc.
Cam - don't know but there is an old thread on here about DRC 7 cam and heavily modified RH4 head which had been on my road bike, Plazz has both of those in his war chest but may or may not have used them.
Barrels - last i heard still cast iron.
Gearbox - TTI.
will be following their progress with interest from here.

Could you post a few details of the machine ? Pictures only show the outside (unless the internals are on the NZ secret list).
As you so rightly say, Donnington is an opportunity to run open exhausts - as is the I.O.M.
In a world slowly being overmanaged by meddlesome doo-gooders and politically correct fanatics, the few open exhaust meetings still available for us to enjoy are becoming increasingly rare.
