Whitehouse tank and fuel indication / range

[jtopiso_imp]

Thanks!

I've become convinced that there was a bunch of unusable fuel in the stock tank (2017 at least...) I'm at 202 miles on this tank-full and still have 2 bars and plenty of visible fuel left when I look in. Or, maybe it's just that the fuel gauge, when in the stock tank. read empty early? I do know that when I removed the fuel pump / gauge / float from the stock tank and tried to drain the fuel out of the bottom opening, it took a ton of effort to get the fuel out. It seemed that there were lots of nooks and crannies for the fuel to hid in.

For my riding, 165 miles is as good as 250 miles so far as range is concerned. The interesting thing though is that once the first 90 or so miles tick off, the fuel gauge seems linear all the way down to zero. I'd have thought that it would be non-linear given the different tank shapes....

I have done 260km on my last tank. Fuel range indicated 25km left. I filled up to the top plate in the filler neck, and only 13 liters went in.

So I see several options:
a- '17 tank is not as big as advertised
b- not all fuel in the tank can be used
c- fuel gauge/range indicator is VERY conservative.

I will keep using it as if it was a or b, so the chances of me pushing the bike will be lower, but I assume c is the right answer
