How far do you go with the fuel gauge flashing?

Another vote here for 60 miles (100km) if you are cautious. I just did about 65 kilometers with the light flashing and I was only able to put about 5 gallons of fuel in the tank, which means I had at least .5 gallons left.

I just finished a 5000 km look and averaged on the computer is 5.6L/100 km, hand calculater was more like 5.2L/100km ~ about 45 mpg.

I’ve heard the older 2 cylinder CanAm’s use considerably more fuel than the newer 3 cylinder models like your wife was riding.
Usually pay attention to how much fuel gets put in because it gives me an idea how much farther I could have gone before running empty.
Possibly, Its hard on fuel because of the drive system it uses. CVT transmission that lets the engine rev constantly.
I checked with her numerous times on different occasions what her RPMs were, she come back with 56-6000rpms, while the S10 would be running 35-4,000rpms. That gotta eat fuel.
Though it spins very smoothly she said, no vibrations.

Filled up today at 271 miles, took 5.3 gallons so that means still almost a gallon left, that tank could have easily gone over 300 miles.

There's cars the use CVTs. And their rpms run higher too. But there mileage doesn't seem to suffer. Never been able to figure out why. 'Cuz I'm with you, higher rpms usually mean higher fuel consumption.

altitude effects milage , best milage I ever got was in the mountains ,EFI adapting to available oxygen . down on the coastal plains I get 43 mpg on average . plus 10 in the mountains.

Here in the states, in 1996 congress passed a law stating the all vehicles should get 50 mile on reserve. Before that, it was like the wild west and it varied from vehicle to vehicle leaving people stranded. With that said, I can tell from this thread, not many of you are familiar with what I just stated.

With that said, it's obvious that it depends on your driving skills.
The DRz400 I sold had a small tank. I was getting 70 mpg with it. I still had 1/2 a tank when I had to switch to reserve by way of the petcock. i was going to cut the petcock tube down to get more out of the tank before switching.
My current Stratoliner left me sitting on the interstate, 28 mile after going into countdown mode. I was running along a speeds better than posted. Big bores suck fuel at speed and I paid the price for being stupid. lol
With my current CBR1000F, I have gotten 45 mile with the fuel needle in red before fueling up.
My current S10, I have gotten close to 50 miles after it switched over to countdown mode. This is with bags on, fully loaded and running at highway speed with cruise on.
My current CX500 cafe racer just sits in the garage and needs a new home. LOL

I just retired but used to rent several car a year after flying in to areas. Some time I drove hundreds of miles to get to work sites. My vehicle of choice for driving is the Nissan Altama and second would be the Maxima. The Altama has a big tank and good fuel economy. I have driven 550 miles without the light coming on. This car can get over 600 miles on a tank.

600 mile on a bike is different. At 68 1/2 years old, I never pass up a gas station or piss brake or any combination of them with coffee included.


EDIT: What was said about CVT's above.
CVT's keep the engine in the power band where it is most efficient. They use the gearing to adjust speed to the input of the throttle peddle. This is how the Altama gets such great range for the size it is with about 39 mpg highway with normal driving speed.
Smaller displacements always get better fuel economy, so, 1000cc two banger usually gets less distance than 1000cc three banger on same fuel.
There are several cars and trucks switching to smaller displacement engines with turbos and CVT's.
The Ford Mustang dropped the V6 because the turbo-4 has more power, its lighter and gets better economy. It doesn't have CVT but instead uses an 8 speed transmission.
The Honda Africa Twin and Goldwing are going in this path with the DCT.

A comparison between my S10 on this last 3week northern trip and the Ryker in fuel milage.
S10 1200cc twin gear box, averaged 4.5km/100 or approx. 52miles/us gal.
Ryker 900cc triple CVT drive, average 6.9km/100 or approx, 34mile/us gal.

The Ryker is slightly heavier, has larger frontal area and more tire friction with three large contact patches.
Try pushing the s10 around in the driveway and then the Ryker. I'll bet there is more rolling resistance with the Ryker. That with the larger frontal area will increase fuel usage.
When power to weight ratio is reduced, lower gearing is required and you get an increase in fuel usage.

What you said a few post ago about running the tank down on the s10 and how the fuel cools the fuel pump is also mentioned in the Roadliner/Stratoliner forum.
Some members have burned the pump out buy continuously running down to reserve.

85 KMs on flashing at 3000 RPM before I found a spot to to pull over and add 5 liters from my gas can. So didn't actually run out but I am sure there was no way I would have made the next 25 KMs to a gas station.

Where were you that it took 85 km to find a spot to pull over and add gas? :eek:

@jeckyll Just outside Watson Lake, Yukon on the Alaska Hwy on my way from Dawson City after stopping in Whitehorse for a new back tire (the Dempster sure eats up tires...). Long day, was late at night and pitch black on the highway so I didn't want to just pull over on the side of the road if I didn't have to. Fortunately found a road side stop that was well lit to put the 5L in and make it into town about midnight.

My longest was on the Dempster in the rain (hard rain) :D The North does have LOOOoooonnnngggg stretches ;)

Yesterday I went to far and it stopped running! I was going hi speed and getting 23 mpg. Made it to my goal. Afterwards I went home. Next day... I'll go into town and put a couple of gallons in it. 1.2 miles from the house it died. Luckily I had a full can with 2 gallons still on the bike from my trip. I coasted to the nearest driveway and removed the can from the holder and put it in. 2 gallons got me 3 bars on the gage. After about 20 miles of 55 mph the 3rd bar went away. I have found out that I have around 1.5 gallons or a bit more when it starts to flash.

I agree. Whenever I fill up, initially the range frequently shows over 300mi. Of course, it's going to depend on the speed(s) you're traveling. Under 60mph she gets crazy high mileage.

Speed limit around here on 2 lane highway is usually 55mph and I usually use my gps and cruise control to run about 7mph over the posted limit. It’s not flat country but big hills are kinda rare. No matter what type of vehicle I drive I usually get pretty decent mpg.

Back to the op question. My low fuel light comes on around 185 and I know I have 1.5 gallon on reserve so I figure I'm good good for 60 miles (avg 43ish mpg) which means I'd better be at the gas station before 240 miles to be safe.

I may ride slower off the highway but I seem to make up for that on the pavement;)

When OE gives a fuel tank capacity there is a bit of misconception or understanding.
For example the S10 fuel capacity claimed by Yamaha is around 23litres or 6usgals. Now here is the misconception, the capacity claimed is filled to the maximum the tank will hold(to the rim), the tank volume. It doesn't include fuel expansion and overflow breather hoses that are incorporated in the tank. You would not be able to put 23L/6gal in the tank with out the fuel spewing out the overflow which is a built in design to prevent over filling.
So when you read fuel capacity on specs, it is not actual useable capacity but only the volume of the tank size. A manufacturing standard is about 10% of total volume for expansion.
