SUCCESS!
I installed the AliExpress ordered injectors, the bike started right up! I don't understand why the OEMs bench tested correct, twice, but failed to even light the bike at all. With that said, and having to remove and replace the injectors far more than any bike should ever have, it now runs great.
I put just over 10 miles on it, at speeds of 100 mph. I still need to address the right fork seal as it allowed the fluid to leak out while sitting with the previous owner. The brakes were surprisingly not great. I already flushed the brake fluid, so maybe after some heat cycles they will grip better. Expecting a bike with only 10k on the clock, to still have the OEM pads, maybe they need replaced not due to use, but rather age. I'll determine this soon, easily enough replaced if need be.
Having finally went for a run, I'll now remove and replace the rear-end, gear-box and motor oils. Plus, I have yet to install the shift extender cam. Having ridden it only 10 miles, I can already see it needs it! Thank you all for your advice, truly appreciated.
