I normally stay on the bike to keep it leveled as I pump. I learned a long time ago while filling up a 1 gallon can that the pumps at my preferred gas station pump way fast and will make a mess on cans and small tanks so I have made it a habit to squeeze the nozzle up to half way at most to pump slowly. I have been able to consistently get 6 bars and I have never had gas splash all over the tank.I found the best way to fill with the pump is to get off the bike and set it on its sidestand. Then I pump slowly to avoid the splashing, and I just rest the pump nozzle on the bar in the hole. I just fill until the pump automatically cuts off, usually when the fuel covers half of the plate. I have gotten 6 bars every time I have done this. Even pumping slowly, 3 gallons goes by quickly.
