the results are quite different between stock and an engine that has been tweaked a bit....
True, but my tweaked engine/air/exhaust didn't quite deliver what I needed, especially when riding two up as I (we) do most of the time. I just recently went back to the 17 tooth (teeth?) sprocket and now everything is the way I want it... (Except of course that it might be even nicer with the big bore, carbs with acc. pumps, KN's etc.)
