It can make the bike run better. But RC51's aren't known for fuel mileage.
If you baby it, it might break into the low 40's. But who babies their RC51?

Anytime you see a bike with two 54mm to 62mm throttle bodies, mileage is not the immediate concern.

About like popping the air cleaner on a muscle car and seeing a Holley 4500 carb, and asking "how's the mileage". The answer would "Ohhh...somewhere between poor and dismal".

Milage varies wildly on this forum. Search it, and you will find hundreds of posts on the topic. Not PowerCommanders and milage specifically, but most here do run a PowerCommander.

'bout the same to worse really....these really are a couple toilet bowls flushing fuel.

Just to give you and idea....a Honda Civic gets a 54mm throttle body.(On average, pending on the model) Vtec V6 engines vary between 56mm and the largest id a 69mm (for newer models)

And that's for all 4 cylinders! My SP1 gets 54mm throttlebody for EACH cylinder. Madbuyer swapped his for a 4500 Holly doublepumper carburator.
