Dyno and flow charts? The problem with both is that the numbers all depend on the dyno and flow bench and how they are run. Huge differences can be had with both depending on a lot of variables definitely including the test equipment itself. The numbers can be manipulated on purpose too! Making fair and objective comparison runs is a skill and harder do do than most imagine. My advise is don't be a sucker.

Small bore? A 750 is still a short stroke, big bore engine. 82mmx70.6. 1.16:1 bore to stroke ratio. Not nearly as short stroke as our R65's and R100's at a whopping 1.33:1 ratio but . . . . 1.33:1 was considered a REAL short stroke for a long while!
