Well, nsap wins the "What's Wrong With Day Man's Bike?" Award. Filled it with gas and it runs fine, ha ha.

Now to figure out what's wrong with the low fuel light. Unfortunately, the bike does not have a reserve switch, so I kinda need that indicator.

It's called a trip odometer, ya maroons. And if you're really adventurous, some math (maths, if yer BRIT-ish).

If I bothered to look it up, there's probably a new gizmo available with a unit cost of $1.29 that remotely X-rays the tank and spits out the results real time. But the ones I've had to deal with involve the equivalent of a toilet bowl float attached to an arm, attached to a liquid-proofed and therefore irreplaceable sensor, attached to a housing, attached to the tank, attached to wires, attached to a plug, routed to another plug, attached to a cluster, which contains a gauge and/or idiot light, which may not be entirely accurate anyway due to tank shape, age, etc...

How many failure points was that, I'm a bit rusty with me maths...

Oh, what's a 217°C difference between friends?
Growing up, my dad had a company car, a first Gen Ford Taurus. We called it "The Recall Beast" because it had so many.

One of the things wrong was the fuel gauge. It'd get stuck at 1/4 tank and then never move again. Dad discovered it on a trip to see our grandparents, when the car just died on the Jersey Turnpike. AAA came and the guy said, "here let me put gas in it anyway, these have fuel gauge problems." And it started right up.

Ever since, dad has been kooky about setting the trip odometer on fillups. On that piece of poo poo, 300 Miles meant a fill up.

If my OCD/ADHD dad can do it, anyone can.

My 1991 GSXR250 had a fuel gauge.

Day man, if you want to fix this, you guessed it: you need a multimeter.

Take your tank off and drain it, take your fuel pump and sender assembly out and see if you get continuity across the two sender wires while operating the little toilet float thingy up and down. You might even be able to see the problem visually. If everything checks out there, make sure all your wiring etc is ok as well. If all of this checks out, the problem has to be either in the cluster itself or the little light in the cluster is blown (doubtful since it'll most likely be an LED, but possible).

The 650's LCD fuel gauge is hilariously nonlinear, as in it will stay at Full for about half the tank, then quickly drop to 1/4 and linger there for another 50km or so before it goes into Low.

Also the tank is supposedly 15 litres, but I've never filled up more than 12 even when I've rolled into the gas station with the low fuel light angrily flashing at me.

Most bike fuel gauges do this (the hyoshit has one!). It's because the fuel level sender is a generic part with a linear relationship between level and resistance. Unlike with cars, it costs too much to optimise the gauge for the shape of the tank and most bike tanks get narrower near the bottom. So when you get to the second half of the tank, the level drops much more rapidly as less fuel needs to be used for the level to drop x amount.

I'd love to know if goldwings and other fancy bikes where the fuel gauge is expected to be accurate do this. One would reason that making it properly would be worthwhile on bikes with high price-tags which are intended for touring.

Short answer: almost certainly not. The fuel gauge is basically an idiot light, because you're an idiot for not accurately tracking your mileage vs when you have to switch to reserve.

On my bandit, the gauge has five bars. It shows all five bars as I ride away from the station. Within a mile, it's at four bars. Five to ten miles later, three bars. There it stays for the next hundred miles, mabye one-twenty. Then two bars. Then one blinking bar, which stays for fifty miles, or maybe ten. When it's no bars plus blinking gas symbol, then it's within five miles of having to go to reserve. That means more-or-less two minutes until the bike starts to hesitate and I have to switch to reserve, which is exactly one gallon from empty. I've gotten 130 miles on a tank to the blinky angry light, but i've also gotten over 200.

Temperature, vibration, magic, phase of the moon, and the proximity of giraffes all affect the fuel gauge, but when the bike starts to hesitate at constant throttle, it's one gallon of gasoline until empty, and ride like a geriatric in a champagne cadillac unless you KNOW you're less than 40 miles from a gas station.

You said you just got a power commander put on? That will change the way your bike consumes fuel.

As for the reserve light, you mentioned the fuel pump just got replaced? I'm 99% sure it has to do with that since the fuel level sensor is usually part of that assy. Maybe the wire got cut going in or it just was not hooked up.

Yes. They were ironically very common in the 80s, but I believe what happened (in general) was that Japanese manufacturers Kaizened the hell out of their motorcycles and tossed every failure-prone Goldbergian assembly they could find out the window, this included. I would point to the difference between a Gen 1 Nighthawk 750 and Gen 2. In some circles, this is regarded as making the motorcycle "boring." The alternative to something functioning predictably and reliably is a kind of excitement I don't really need.

Yes Yes. This is common as well, as pointed out elsewhere. If you want an example in the car world, take the mid 90s Camaro, where the profile essentially looks like a larger version of a motorcycle tank. Install a linear sensor in a triangular tank, and you can guess the rest.

Yes Yes Yes. To put this all in perspective, ferchrissakes the tank isn't a closed invisible unit tucked aft of your position. 90% of the time or better, there's a lefty-loosie, righty-tighty thing about a foot in front of your nads, and when you combine it with the two ocular fuel sensors just north of your pie hole, it pretty much tells the whole story.

A lot of bikes have a sort of saddle-shaped tank to maximise airbox space so looking in the tank is even less useful than a fuel gauge. Also "HEY GUYS ITS SO EASY YOU DONT NEED A GAUGE JUST STOP THE BIKE AND LOOK IN THE TANK EVERY TEN MILES!!!" is the most ridiculous argument yet in this weird neo-luddite derail.

This is the same strawmanning and over reacting bullshit I see every time someone whine about how the only starter bike ever recommended is a ninja 250 and "everything else will kill you".

edit: I was really having trouble figuring out where you got that caps locked bullshit from then I realized you're the only one with a tank small enough that you'd need to do that.

"Check your tank level with your eyes" does not seem like ridiculous advice, especially considering that someone just ran out of gas and hadn't checked with their eyes.

My tank has a saddle shape internally, and you can't see the fuel when it drops below like 2/3rds full. I'll be looking into what's wrong with the low level indicator.

Edit: also, I'll feely admit that running out of gas with three years of motorcycle experience makes me a moron, and I think its hilarious. Its funny how worked up everyone has gotten over it

Yes, by all means, take the option of last resort I noted, add some ridiculous parameters, then label the result ridiculous. Brilliant.

In summary: If you have a broken or nonexistent gauge, and haven't bothered to calculate your bike's range under common riding conditions, and have ridden it so seldom that you haven't yet developed a feel for it, then check the tank. If you have some sort of holographic rhomboid tank that renders your eyes useless, shake the thing side to side and listen.

This argument is idiotic. Back in the day, we had a reserve portion of the tank. Now the fuel light is there to indicate that portion of the tank. It's pretty ridiculous to go around without any reserve indication and just count miles whether you are a carb-hugging harley lover or a tarted up high tech pill bike guy, so the solution is simple: fix the low fuel light so it comes on when the tank is low. This is the reserve.

Or you could shake the bike and listen for slosh...
