Mileage question

2003 Busa, Brock's Alien head full exhaust, air box mod, PC4, otherwise stock. What kind of mileage are you guys getting? I'm only getting 25 miles city. Is that an acceptable mileage? It seems really low?


Sounds like your cruising at 150 plus ! Just kidding... Yes, somethings not right. Have you looked at your plugs lately? If one plug or cylinder has a problem this might get you pointed towards the problem. I wonder if the airbox is causing some kind of problem?
I get between 38 and 42 normally. Gen 1 05 model.
