Since there is still a possibility of some confusion here........
I suggest that you fill the tank and start over with your test.

As others have said, there is only one tank and "reserve" is just the last .8 gal (or whatever) in the bottom of the tank.

P.S. I am now going to go back and correct my incorrect post about the lever position; the one in this thread anyway. I can't find any others.

That's weird, because in the picture with your first post in this thread, your petcock's handle points forward, which is the "run" (normal) position, not "reserve".

And by now you probably realize that in the "run" position, the petcock drains fuel from the tank through a tube that sticks an inch or two up in the tank so it cannot drain from the bottom, and in the "reserve" position it DOES drain from the bottom of the tank via a shorter tube.

PS: From the manual:
Tank contents: 3.7 gallons (includes reserve) (California models: 3.4 gallons)
Reserve: 0.8 gallons.

PS2: I switched to reserve yesterday at 196 miles, after the engine stalled at a traffic light, with the road sloping down slightly. I rode about 20 miles and then filled up with almost 3.1 gallons. 70.5 mpg for this fillup.

This is weird. I assume that they don't put a different tank on Californian models. Like my handbook says 13.0 litres, 14.0 litres for Canada (when litres are the same all over the world) I wonder if they mean 3.7 imperial gallons, 3.4 American gallons? Velly stlange!

That wasn't my picture of the petcock hehe handle, someone else posted that. I didn't read these replies yesterday and was going to the country last night and didn't want to get stranded, so I refilled my tank at 200 miles and will restart my 'mpg test'

And I think that assumption is incorrect.
The California model has an extra "gizmo" up under the tank, charcoal canister for gas vapors, I think, that requires a "dent" in the tank to go around it.

Not sure, but didn't someone say (a long time ago) that the cannister was UNDER the bike. Can't remember rightly, but I think it was Alan McC.

OK, well maybe it's the plumbing that goes along with it........I said "I think".
Anyhow, the tank IS DIFFERENT.

My GZ averages 45 to 55mpg with my fat ass aboard.

:lol:

That's something to think about if anyone on here is looking to buy a new (to them) tank.

That would only be a problem if you live in California and buy an out of state tank. We would not consider an out of state tank and removing the cannister and associated plumbing.
