Question tell me of the fickle fuel guage.

One of the things that turned me on to the VN750 was the instrumentation. Not only is there a tach to go with the speedo, all the idiot lights on the handlebars where they're easy to glance at (instead of over the gas tank as on many middle and low weight cruisers). And best of all, a fuel guage and trip counter! No guessing about the fuel mileage or level!

After one week of riding (mostly in 3rd gear and under), the fuel guage had dropped to just to the left of the "F", just shy of the red line, at only 90 miles on the trip counter. (I bought the bike with the counter reset and the tank ostensibly full.)

I went to the gas station for my first fill-up. And I filled it right up to the top of the tank... with just two (2) gallons!

I thought the tank was 3.5 gal? Or is a full gallon in reserve, and the guage exclusive of what's in the reserve tank?

Sounds like the gauge is probably close to being right on target. The fuel tank is about 3.5 gallons, and folks are getting 45-50 mpg. So you're right in the ballpark. And, typically, once the gauge begins to go down, it seems to drop exponentially (my Honda does the same thing). I keep an eyeball on the fuel gauge, but generally by 110 miles, I'm looking for a gas station.

I think reserve tube on the petcock takes over with about .5 gallons left.

I fill mine to the lolly-gills and usually when the hand is dead center on the full mark I have about 50-55mi on the odometer, then at about 100-110 it is on the 1/2 mark, and at about 150 or so it is on the red empty mark and will start to miss at anytime, so then I am ready to switch to reserve for the last 1/2 gal. and hopefully close to a station...lol... It don't even move for the first 40 or so miles after fill up... If it would get as much gas milage as it first acts like, I would probably get 500 mi to a tank, but as Cindy said it drop like a rock when it starts...

I ran out (purposely) to see how many miles it would get. Well, out with the petcock to on. 132 miles, and took 2.6 gallons to fill up. Of course, I rode it pretty easy on that tank. I figure 120 miles and it's time for gas. Now the last bike I had, there was no fuel gauge, and the reserve switch was broken. Learned to keep a close eye on the mileage.

After running out of gas.

Twice.

How do you switch to reserve? Does it happen automatically?

The petcock lever is on the left, under the tank. Move it counter-clockwise to the 9 o'clock position for reserve.

Or if you are sitting on the bike, push it forward.

What I meant to ask was, does the fuel indicator on the dash include, or exclude the reserve? Meaning if I suddenly realized out on the road that my guage was on the red F, I should just flip the petcock to Reserve and start lookin' for the nearest gas station post-haste?

My guage was right on the E when it ran out. So you can change it over to reserve before it runs out if you're comfortable with that. Then find the nearest station. If it runs out then, you're gonna be pushing it.

Pretty much it excludes. The guage is in no way accurate. It gives and approximate. Even if the indicator is showing empty, I don't switch until I start feeling the engine bucking from lack of fuel. Just remember to switch back once you fill up. You'll definately remember after the first time you reach for the reserve and realize you have been running the bike on it the whole time.
