So as not to thread jack From previous thread I fill it to full and the last time I put 3.381 gallons of premium after 158 miles and that was when my reserve was switched. I just put a new speedo on it that's in miles vs the previous one in Kilometers, I used a conversion app to figure out how many miles I had went. I have only filled up once since I got the bike, so how consistent that will be idk
