It takes a set amount of horsepower to drive a bike at a given speed, and it doesn't matter what the engine is capable of. A stock bike, making 35 horsepower and set up with an air:fuel ratio of 14:1 will deliver the 15 horsepower required to drive the bike at 65 mph down the road.
A modified motor, capable of 45 horsepower and set up with an AFR of 14:1 will deliver the 15 horsepower required to drive the bike at 65 mph down the road.
The above is simply the laws of physics and thermodynamics.
What will be different will be the throttle position required to make that horsepower.
If, after modifying a motor, the fuel economy suffers greatly the usual cause is one of three things:
a) an extremely rich AFR.
b) the mods have mad you so happy that the bike is being ridden like it was stolen.
