Where did the 0.5 gallon Go?

Getting to know my newly acquired 2006. Ran some Startron in with a full tank of gas in a bike with 15k miles. A 130 miles later, the fuel light came on and two miles later, we found a gas station. 3.6 gallons to fill her up. equates to about 36 mpg. If there is 0.9 gallons in the reserve, where did the other half gallon disappear to in this 5 gallon tank?


Happy with my initial impressions of this bike. Thinking that increasing the current stock sprocket gearing to a 17 in front and perhaps lowering the number of teeth in the rear would help gas mileage for her intended highway use and still be more than adequate in the lower gears.


From a Newbie, Thanks for chiming in.

I thought the tank was only 4.7 gallons? There is no reserve

It's a 5 gallon tank, and you can get 5.2 in it from completely empty if you take your time

It's a 5 gallon. IIRC the owners manual says to not fill completely because the heat can cause the gas to expand. That's why people get more than 5 gallons in. I personally fill it to the very top.

Just ride!

I think the issue isn't so much the size of the tank but where the low fuel light sensor is in the tank. It seems to vary a lot between bikes. You may be able to reposition it but that could require removing the fuel pump.

That would explain why mine always seems to come on around 90ish miles. My fills are generally 3~3.5 gal. Maybe I should push it just to find out how much I have, but I'm concerned about running an EFI system dry.

That's what I thought. She's never got very good gas milage but I figured it was because I do almost 100% stop-n-go in city traffic. I don't drive a car and haven't for a few years, so the bike is a errand runner and I figured that without many freeway miles, the MPG would go down.

I don't know what else to check. I guess I could do a freeway trip just to see how it changes.
