If it is a stock paper filter, no it needs replacing, if it is a k&n high flow, yes, clean it with k&n filter cleaner and rinse with gentle running water let it dry and oil the filter with k&n filter oil.
That's not a complete sentence, but the Sportster was introduced as a replacement for the K Model in 1957.
K&N #170c
their website will give best directions, but water will work, then treat with k and n filter oil
Fuel milage varies from bike to bike. My best answer is this comparison , MY 2007 Nightster with Vance and Hines exhaust and K and N air filter gets 52 MPG . My 1976 Sportster with _65A mufflers and S and S Super B gets 25 MPG. Age and modifications , riding style, air pressure, etc, Affects fuel milage . I hope this answer helps.

In most cases the filter will have a nominal effect on performance.Of course that's when you're comparing two clean filters.A clean filter gives you a massive improvement over a clogged one.
Filter it through a Brita filter since the beginning of time. J/K, special fine pored mesh like filters.
Try 24 hr filter cycle and more chlorine. And clean the filter frequently. k
I use a mild dishwashing liquid and water mixed together then spray it clean with water under pressure such as a garden hose, let dry and then apply k and n oil. Works great everytime and I'm still using a 5 year old filter.
What was your clean starting pressure? When was the last time that you backwashed the filter? When was the last time that you broke the filter down and cleaned the grids in the proper manner? Sounds like your filter is getting dirty. k
