250+ miles to a tank.....can of worms opened

[Fuzzygoth]

At a guess I would say that bikes are built on the basis that you aren't
going to brim the tank. The manuals for my bike (i think) have said you
shouldn't fill the tank past a certian level (which everyone I know ignores)
so I'd guess that extra bit that is supposed to be left unfiled along with
the pipes and tubes might account for the extra? Or maybe the reserve
level is set higher than listed for people who ride thier tanks into the reserve
(which I done only last week).
