Lee is correct.

Think of the the right tube as a crossover to keep the two sumps in the tank at the same level. If the RH tube were plugged, you would have reserve but it would only MT the LH side . I'm thinking a petcok rebuild and tank cleanout is in order.

On mine the steel elbow was plugged with shyt.

That would make sense, and is a clever design, as the center of the tank is raised where it fits over the frame, meaning you have two separate pools of gas on either side when it's low. Could've been yesterday, for whatever reason (road conditions, the kinds of turns I made on my route home, etc) that most of the gas left in my tank was on the right side, where the tube is plugged.

Hey andy,
just posting here to keep with the conversation, but the high middle of the tank in the rear is lower than the petcock flute pipe which rises up from the bottom of the tank to about 2.5" up, about 1" above the rear separation point. If you want a little extra milage from the tank, shorten that brass pipe on the petcock about an inch, and reconnect the reserve hose. make sure that it flows through from the reserve setting after you reconnect them

Ya, i figured. I might just connect the reserve pipe from the tank to the pipe from the petcock, see if that works. Is there a particular reason people plug the reserve?

If could be that the reserve port is rusted out (typical) and no fuel runs through it anyways, but also it's just a hassle to deal with when taking off the tank because the only way to make it work is by running it under the backbone of the frame, basically strait across to the petcock. Some say that if you run it above the frame it will prime itself and pull gas out of the tank, but gravity begs to differ. What I did is I ran a longer hose, about 18", under the backbone so that its lower than the gas level and will feed to the petcock while still allowing access to the carbs without unplugging the reserves.
Works for me, but knowing your bike I dont think you'll need to get in there that often, so I'd say run a hose strait across, and unplug it if you ever need access.

Andy,

Crossover was plugged to ease removal of tank. You can lean the bike over to slosh fuel onto the other side of the tank. another good way to do it is to get a dual inline shut off for the crossover line. That way you get full rwesrve, and the tank still comes off without all of the hassle of completley draining it.

gotcha,

I was thinking about how there's no "off" for that side, could be a hassle to remove the tank. Sloshing the fuel to the left sounds easier, as there's always gonna be enough fuel on the left side to at least alert you that it's time to fill up.
