Usable fuel capacity on ST1300

cravenhaven:
Went for a ride in the country today without filling up first. I thought that 3 bars on the fuel gauge should get me to the highway where fuel is generally cheaper. Anyway, I got myself into a nice remote area when the low fuel indicator starts flashing, then managed to make a wrong turn (you know how it is  :whistle ) and the remaining fuel is steadily and worryingly decreasing. At the point where the computer gives up trying to figure out life expectancy, I am in the middle of some hill country and I carefully nurse it along, hoping that civilisation and an open petrol station will appear soon. At last I see the signs of a town coming into view and pull into the servo, fill up but note that it only takes 26L of fuel  :think1.

So what happened to the other 4L that I thought the ST held?.

Does anyone have some insight as to how much fuel it should have taken to fill up from "apparent" empty?.

I saw exactly the same thing a few years ago in Rockhampton at a very small single pump shop.
I put it down to the pump doing the unlikely: under-reading.

YoungSTer recently experienced the opposite, and challenged the attendant who said they knew of the error and gave them a $2 credit.

I run a spreadsheet which calculates the expected remaining range based on one litre unusable, and it always agrees with either the "count-down" or my projections based on recent consumption.

Regarding the "count-down" facility- you have probably seen for yourself it loses the plot if you shut down and restart the bike.  It's only reliable if read continuously.

I seriously doubt that the pump was under reading by 15%, although it is a country servo.
As I said, I was riding continuously so stop/start errors wouldnt have occurred. I have seen this sort of effect with other vehicles as well and it seems quite reasonable that when so close to 0 range left the startup usage is going to have a significant effect, particularly if it is a cold start. I had this happen with the same bike many years ago when I got home from a ride with something like 40K left flashing on the gauge. Next morning I start the bike and get to the end of the (very short) street where it promptly stopped.  Its a damned heavy bike to push :)

Gadget:
The spec is 29.2 litres as Totgas posted very recently in another post.

I've deliberately run mine to empty on a run back from Rockhampton and got to 565 km before running out with no coughing at all before empty. Topped it up with 4 litres and rode another 60 km and then filled up with 27.5 liters.

Thanks Gary,
From what you reported it would indicate close to 30L capacity. I've had over 550K's on a tank as well, but I dont remember how much it used to refill that time and thats why I was so surprised that it only took 26L when it was indicating that it was empty.
I'd had a problem with the battery this morning so I'm wondering if that confused the trip meter, still I would have thought that a 250km run would have given it time to sort itself out.
It'll be interesting to see what it reports on this current tank full.
