Nope. Not particularly true for carbed bikes, and certainly not true for FI bikes. An engine is nothing more than an air pump, and other than when under load (say during acceleration) the sweet spot for air:fuel ratio is approx 12:1 to maybe 14:1 for efficient combustion. Even if you're talking carbs, the fuel is drawn from the bowl by venturi, which is largely dependent on RPM at SS cruising. FI controls fuel flow based on a number of parameters, including throttle position, RPM, engine temp, manifold vacuum and exhaust O2 level.
Some people will tell you that slow is good, and it may be on some days, but I am here to tell you that fast is better...
