Reserve Tank

Postby Jewood20 » Fri Oct 07, 2016 12:28 pm



I have a 92 GL1500A and I was wondering if it has a reserve tank? I think my "gas tank is empty" light has gone south so I was wondering how far I could ride before it ran out of gas. The last test I did I got about 175 miles on about 4.5 gallons of the 91 octane gas. Thanks for your input.

No reserve that you can switch to. Only reserve is what is left when the light comes on.

The low fuel light failing is usually due to a failed thermistor. Do a search for "Thermistor" and you'll find lots of posts on it.

There's been a lot a talk about this, but in a nut shell, the GL1500 has a 6 gallon tank. The low fuel light is usually set to come on when 5 gallons have been consumed, leaving 1 gallon as a "reserve".

Wear and tear, abuse and improper handling can cause the components to mis-read or fail. Do a search and you will find all kinds of methods of repairing ailing fuel systems in this forum.

As posted above, the light is SUPPOSED to come on at 5 gallons gone (mine does) , but I have also found, on my bike any way, that the last .3 of a gallon can not be picked up by the fuel pump, so you really have about .7 gallon "RESERVE" or about 23 miles if you get 33mpg average. I hope that helps some. . . .

With my '99 and my '98 Aspencade's, the light would come one at about 5.2 gallons of consumption. If the light is not on by about 188 miles, you should stop and refuel. If the tank does not take 5 gallons, then you have not gotten to the low level yet.

Thank you all for your input and experiences! I think right now I'm at around 150mikes on thiis current tank. I'm going to try and push to see if the light comes on. I'll let you know in about a week. Thanks again!

Use an empty SeaFoam can to carry a little gas so you can test the range of your fuel tank. When you have figured it out you can remove the SeaFoam can and be confident in your fuel range/consumption.

I, for one, never trust fuel gauges (ask me why!). My technique is simple - when I refuel, I always reset the trip odometer. I know that I can always count on getting at least 300 km out of a tank, without the fuel light coming on, so I refuel at 300 km religiously. I do the same thing in all my vehicles, and it's foolproof.

Agreed. As I said earlier,

And I never depend on my miles driven to determine when to fill up. I rely on my fuel gauge. There are to many "riding conditions" that affect mpg vs miles driven. Wind, terrain, speed, load, etc. Suppose I ride at 85 mph against the wind vs 60 mph with the wind. That's 30 (or less) mpg opposed to 45 mpg. What are you going to rely on? Mileage or fuel gauge????

In my case, mileage...for my bike, 300 km is the worst-case scenario (2-up, fully loaded, windscreen all the way up, pushing hard over the mountains, etc.). No matter how bad I push it, I can count on 300 km minimum, without the fuel light coming on. I've calculated my normal-case maximum range range should be over 400 km, so I'm leaving myself lots of reserve.

It kind of makes you reminisce about the petcock mounted below the tank that was switchable from RUN to RESERVE. When you had to switch to RESERVE, you KNEW it was time to refuel no matter what the odometer said.

Then there was the time when you forgot to switch it back to run after refueling. Now THAT was an eye opener. A lesson learned like that really makes it stick in the memory. Never again did you forget to switch it back to run.

Of course, that would only happen to you when you are running from tank to tank refueling on a long trip because you ALWAYS remembered to switch it back to OFF when you parked it. If left open it would flood the carbs through a not so perfect needle and seat in the float bowl.

The 1500 is rated at 6.3 gallons. I put that much in my 94A when I deliberately "tested" it when I bought it new.

When I ripped out my thermistor and replaced it with a float switch for the "low fuel" light, I calibrated it by running the fuel pump and plumbing it into a gas can, until the fuel pump ran the tank dry. I then put exactly one gallon into the tank, and calibrated the float to just come on at that point. That way I know I have exactly one gallon USABLE when my low fuel light comes on.

Do you have a "How To" on that mod ? I don't know if I would do it or not, but would love to read more about it. . . . THANKS

Thanks everyone for your awesome input. It looks like a lot of you got something out of my simple question! I decided to push the bike a bit further than my comfort zone. And... The light came on! I fill up with gas and I believe that I can safely get 175 - 180 Mile out of the tank. Thanks again!
