50 to 55 series rear won't cause a change like that.
Now, On mine, the biggest thing I've noticed that causes my mileage to drop is 2 things...
1) riding into a headwind with my tall CB windscreen all the way up.
2) running ethanol, 87 octane gas instead of pure 91 octane gas.
My mileage drops dramatically when experiencing either.
