Let me start by saying i know there are many variables that impact MPG. Having said that has anyone puposefully ran their bike dry to determine how many miles can be run after the light starts flashing? Again, I know that figure is subjective but generally how many miles are availible before the bike runs completely out of gas and you are stranded once it starts blinking. It case it matters...its an '06.

If you keep the RPM below 5K only two injectors out of the four are spitting fuel ie fuel savings is on with the reserve and that RPM figure in mind you can get close to 42 miles

When the last bar starts flashing you have approximately 1 gallon left in the tank

Never ran mine dry (have an 09), but I think the reserve is approx one gallon (someone correct me if I'm wrong). Easiest thing to do is fill up, set one of your trip odometers to 000, and ride a while. At next fill up see how many miles you went and divide that by the amount of gas you have to put in to fill up again. Gives you your average miles per gallon. If the reserve is approx one gallon you know you can go approx "x" miles....:cruising:

This I know. I do it almost every fill up my car. I never trust the manual and how much it says as far as gallons left in tank after the light blinks. I usually run it dry once when ever I buy a new car, just so I know exactly what im dealing with. I don't like running it dry but i figure once in the life of the vehicle is acceptable.:shakehand

don't ever purposely run any vehicle out of gas. It's hard on the entire fuel system, plus you don't know what kind of crap is in the bottom of the fuel tank that will get sucked into the fuel pump/filter.

Ride your bike until the last bar starts flashing. Go fill up your bike, it should be roughly 3.5 gallons. Then you know you'll know how much fuel you have once it starts to flash, and you can go XX number of miles based on your average mpg if you've been tracking it

I guess I don't quite understand your inquiry then. I'm not trying to start any arguement or anything but in your original post you indicated there are several variables on mpg. Obviously how hard you ride, level of rpm, etc factor in. I can tell you I average approx fifty miles per gallon, that's about fifty percent highway to and from work and fifty percent around town/ just riding. I might get fifty miles on my reserve gallon but unless everyone on here rides the exact same way some will get more or less. If you already average your mileage out when you fill up you should know your approximate reserve miles for the way you ride your bike... Just my $0.02 :ponder:

+1 on not intentionally running any vehicle out of gas

Not sure if these pics are too small as I'm uploading from my phone but I went ~188 miles and it took 4.4 gallons.

This is 100% highway riding with an average speed of 90mph. No top speed runs or anything but lots of cruising through back roads at 100-110.

I've never gone that far on a tank and considering I was in the boonies I would never want to again. I came .15 gallons from having to start pushing.

Edit: and my odometer is not off.

never felt like an idiot more than that one time my car ran out of gas, ever since that, i kinda assume the flashing bar is a countdown timer to a bomb that can only be diffused at the pump. works like a charm, never had any explosions

Under 5500rpm and 50 degrees of throttle rotation only the 4 main injectors are on, and not the 4 secondary 12-hole injectors.

THIS ^ and the fuel also provides some cooling to the pump in majority of vehicles

Not saying you'll burn out your fuel pump but maybe decrease its longevity.

When I forst got my bike, I rode it low on purpose to make sure that the last damn bar would flash...... I ran out of fuel... Ask me how I know??? My last bar didn't flash and I was at 154 miles on the tank.. I also didn't fill it all the way up for my first time ever fueling up the bike.


Now I run the bike til about 140 miles, I don't care where my bars are. Those are VERY INNACCURATE!!!!


I am averaging about 37 mpg.

Yes...this is my point. I know that based on average fuel consuption of the main tank will give you the average MPG... assuming there is ACTUALLY 1 gallon left when the bar starts flashing. You can have 40 MPH and when the bar flashes you may think u have 40 miles until u run out but if you dont have a gallon in there then you are not going 40 miles...hence the real world test.

Don't get me wrong. I DO NOT make a habbit of running my fuel tanks dry however, 1 time to do this test will not hurt anything. Let me stress only doing this ONE TIME.

So my my question was if anyone has done this real world test so I didn't have run my tank dry.

I have never had a gauge in a car/boat/bike that was accurate. At least not enough to gamble wlking or pushing the vehicle.

ED, Man I am lucky if I get 120 miles before my light flashes! I swear I drive pretty modestly with the occational full throttle twist. I would need to get like 60 mph to get to wear you were....lol

like I said above, ride until you only have 1 bar left on the gauge, or the last bar flashing whichever you choose. Go fill your tank and see how much fuel it takes. then you will know how much fuel you have left once you get to the last bar.

Everybody will have different distance/mpg answers because we all have different setups. Some burn rich, some burn lean, some have autotune which constantly changes mpg, slipon's, air filters, powercommander, gearing....... it all changes mpg so nobody will be able to give you a definite answer

Well one time I ran out of gas. Not on purpose. And I pushed it home. Luckily I was close to home. Don't do this.

Gonna run some cleaner through it lol.

I averaged more than 40 mpg on my gixxer, city. I wasn't romping but I wasn't driving like grandma Gail either
