so if one could maintain a consistent temperature across the exhaust system, would that minimize the effects of air flow fluctuation due to the changes in exhaust pipe temperature?
i agree that if you can make more power with a carb system over an fi and keep the reduce complexity of the fuel system that fi would not be so impressive.

side note or way out in "left field"
ive contemplated if you could somehow combine the reed and throttle system in to a single operating unit and use a fuel injector or multiple injectors to directly inject pre mix into the crankcase, similar to the idea of direct injection on automobiles. would this allow a designer more freedom to play with port design rather than to fall into the constraints of using the same combination of carb to reeds to crankcase to cylinder...
