Unfaired, special chassis, 1000cc, no added boost? You'd end up running in Special Construction, in the A/G 1000cc class.
Unfortunately for those of us who run in this class they (the powers to be) allow modern sportbikes to remove their faring and run in the same class without any chassis mods, so as Joe said earlier in this string it's hard to be competitive running an older style engine in this class.
Still it would make a great looking ride and I'd like to see it run....good luck.
