Hawk 250 power/gearing downfall?

So, I've done a fair amount of looking around, on various different sources. I know the 17/45 combo is the tested and true go to for these bikes. I've heard people claim they have had luck with other combinations as well. The lowest ratio I've seen verified was 17/40, but only with claims of top speed improvement, and no mention of the effect to the low end of the power band. I cant find anyone that can verify a particular gearing ratio of 17/34 (2.0 final drive). In theory, according to online calculators, with a feather light rider, this combination could reach 100mph+!!! But my fear of this ratio is that the little single cylinder would just fall on its face trying to spin the rear wheel. Would you lose all acceleration from this and spend days trying to get up to speed? Or is this little 250 with say, a carb and exhaust actually up to the task?
