don't have mileageindicatr? most of the bikes don't have mileage indicators, and it may sound a silly question but how do U exactly measure how much average/mileage u r getting? as when the fuel starts becoming less as seen on the fuel indicator, we fill it again but this way we can't measure it. If we wait till the tank is emptied then we may get air-locking or other problems due to lack of fuel/gas/petrol. So how exactly do U measure/calculate. This is a general question for all vehicles no specific.
