Gurgling Monk,

+1 to IDoDirt. Find the cause, it is not normal (or safe) for there to be excess
fumes from the bike while indoors. Check all of the connections (older bikes
tend to lose hose-clamps), as mentioned check the lines themselves.

Scope out the fuel-filter as well for cracks/leaks. While you're checking the carbs,
be sure the bowl-drain plugs are seated firmly. (No gorilla arms here! Just that they are snug.)

To the original thread...I, too, eye-ball and reset the trip odometer as a fuel monitor.
Unless I'm going long distance (to conserve 'down-time'), I try to re-fuel before the
engine stumbles. I generally always leave it on main.

If I note that I'm getting close on the main, I'll go ahead and switch to reserve and
then...finding a gas station becomes top priority (again, good advice IDo).

The tank doesn't have a seperate compartment for the reserve. It just draws from a different level in the tank (via a pipe) for the main supply.

If you run an occassional tank with a stabilizer/carb additive, they will 'lock' any
condensation that forms in the tank and remove it. Tank 'slosh' will keep everything
else homiginized. i.e. the gas won't go stale over time, if you don't drain that last
couple of inches, occasionally. The fuel filter catches the rest after it leaves the tank.
