This is the direction the TTf1 replica would go, but without the lower fairing (trim the upper to flow a bit better too) and different paint.
ideally the engine would get a custom exhaust, ST2 cams and FCRs (944 eventually), braided lines and 1098 master cylinders, Woodcraft rearsets. probably run dual oil coolers too, one at the horiz. intake valve cover and one in the actual upper at the letterbox slot. I would ditch the oe gauges (except the oil temp) and just run a Scitsu tach. If i fell ass backwards into some Ohlins or a wider rear rim I wouldnt be upset either.
Most of that would be done for the resto too, and since im currently riding it I imagine I would move do most of those things as things break.
