Wow, very crisp and powerful.

360° crank?
Cylinder displacement?
As stated previously, I'm not curious at all (but would like to know 'bout some key data) ...

A torque monster. From 3k it rips your arms off and goes through 1st and 2nd like a trail bike, changing at about 5k. High gearing too - 19-37 and 28.6kph/1000 revs - 100kph on the GPS speedo is 3500 pm. Can't use more than about 1/3 throttle or big revs at the moment because the FCR 39mm carbs haven't been set up on the dyno yet.
Hmmm, some of the key data

... the nitty gritty ... I'll make a thread later of where the other several hundred hours went
270 degree crank, Carillo rods on a genuine SFC factory crank, dynamically balanced by Red's man in Brisbane, pinned mains with bronze cages. 880cc, 87mm 10:1 Ross racing pistons with crowns profiled to match the SF head (thanks Red!!), 7mm valve stems, larger exhaust valves, extended intake manifolds, inlet port angle steepened by 5 deg, 39mm FCR Keihin carbs, ports 37.5mm into profile throats, std exhaust valves smaller exhaust ports, head ported by me and finished by a top flowbench guy (Phil Tainton), custom exhaust system, handmade by me (and a welder!); smaller headers from head to under the engine; from siamese X it starts to taper out gradually from 39mm ID headers to 51mm at the exit of both 'mufflers' (it passed roadworthy - i don't want it crazy loud), straight through but packed external baffles around perforated tapered tube. SFC 5/C cam, degreed and advanced 5 degrees from std, Ignitech ignition, double row oil pump etc etc
Front end is Yamaha YZR750SP (1993 homologation superbike) forks and triple clamps, adjustable comp, rebound and preload, steering head angle reset to 25-26 deg rake, R1 calipers and R1 radial Brembo m/cyl, Ducati 996 rotors, Honda alloy swingarm (45mm longer to compensate for lost wheelbase from rake change and place more weight on the front end - probably gone from 48 front, 52 rear to opposite (52 front, 48 rear), Nitron fully adjustable piggyback shocks laid fwd, motor set 3mm to right and extra clearance in frame for 160/60 x 17 rear tyre and 520 o-ring chain, front 120/70 x 17.
That will do for now - keep remembering stuff!
As you can see the SFQ was never just about the looks!
