The very first tank of gas through my Max(dealer Provided gas) got 88 miles to the low fuel light. I filled up right away. That tank also had alot of sitting in the garage just listing to it, damn thing just sounds so good even stock. I don't ride it daily and have had family in town so I haven't finished the second tank yet. Although I have just started getting used to the bike and playing with boost(that **** is adictive so I dont think my milage will be any better.
