Last year after every fill up, the "miles until empty gauge" would settle between 180-190 when filling up.

Over the winter, I changed the air filter to the heavy breathing cone style from the stock looking high flow filter. (Thank you Harley-bucks)

Now the bike has noticeable more power/ grunt, AND, the "miles until empty" went UP to around 230.

Seems strange, but I'll take it. Does it make sense?
