How do you know when your tank is low on fuel?

[Jsmith8695]

The problem is related to the shape of the tank and how the guage is made.
Think of the tank like a gallon jug that has a smaller diameter at the top and a much larger diameter from the upper 2/3 to the bottom. The gas gage inside the tank is a float on a straight stick without any compensation in measurement for the diameter of the tank. This results in inaccurate measurements until you reach approximate 1/2 tank (when the diameter equals out to its full size and is the same to the bottom. When I fill my tank autonomy displays only 120 miles. As I ride my guage will eventually start to drop slowly and then suddenly display 1/2 tank. At this point, it is displaying an accurate level and is fairly accurate. I know that I get approx 185 miles per tank and the low fuel light comes on at 35 miles. I monitor the trip reading for miles driven add the autonomy numbers for miles left. The autonomy reading is close to actual once the tank is half full.

I use my riding crop to measure the fuel left in the tank while going down the road, then I continue whipping my bike for more speed down the stretch.

Can someone explain the issue with just using the fuel gauge on the bike? When I fill up the gauge indicates approximately 277 miles and I have ridden it down to 60 to 70 miles before fill-up. Now I’m not sure if this is actual miles or an estimate based on how hard the engine is running. Would the bike run out of fuel with miles still indicated on the gauge?

What you are seeing is an estimate based on how hard you were riding for the past xxx miles. At around 35 miles to go the mileage figure will change to ----- which is dash speak for "Hey dummy, get some gas before you leave us stranded beside the road."

Have never run out in 30,000 + miles, but I have seen the ----- several times and always paid attention.

Put 97 miles on my bike today,the gauge are working I still have two bars on it.First stop tororrow is the gas station.

My gauge doesn’t;t move from full until i have traveled about 85 miles. Then the bars begin to count down. I find the distance to empty (Autonomy mode) to be the most helpful

It's a Ryker thing - don't know about an F3L. No Ryker will go 277 miles on one tank.

I fuel my Ryker on the way home about a mile from my house. If my ride was 90 miles I would add 3 gallons and be ready for the next ride and after adding fuel my autonomy would read about 125?
