ST1100 Miles per tank

When I removed the tank to add a cruise, I recalibrated the fuel gauge. ST-Riders instructions work as advertised. I do like the guage's more linear readings.

Generally I try to refuel under 300 miles -- but a few times I've gone 10-20 miles over. On my recent WeSTOC trip (2800 miles) I averaged 47.2 mpg. :yes:

I commute almost every day on the ST 1100 and start looking at 250 miles. Took a quick run Battle Ground WA, to Reno NV. Around town 44 to 47 mpg and steady on hwy at 62 mph 48 to 51 mpg depending upon passing. The st 11 is a comfortable locomotive and I don't know anyone who doesn't love a good locomotive.
 
re:

>In any case, after 100 miles, my fuel gauge shows just under half a tank.<

Looks like you are not filling the tank completely. I ALWAYS fill on the center stand. Fill to bottom of filler neck and then pause. Slowly squeeze in some more and pause again. You'll find you can do this 2 to 4 times and the fuel level doesn't appear appreciably higher on the filler neck. The fuel guage SHOULD be pegged to the right when full.

I have not modified my tank setup in any way. If I fill soon after the LFWL comes on, she will usually take in the neighborhood of 5.8 gals.

The one time I actually ran out of gas, she took 7.1 gals. As previously mentioned, you can't use the full capacity because the fuel pump sits a little above the absolute bottom of the tank. (Helps prevent sediment from being sucked into fuel pickup and ensures pump remains cooled by fuel)

In the chart below, the "Theoretical Range" is based on the calculated MPG for that tank multiplied by 7.1 gallons (since I KNOW that's all I can use)

My fuel mileage has recently improved by some 3-5 MPG (from ~42 MPG to ~46 MPG) because I replaced my carburetor slider diaphragms, 3 out of the 4 of which were torn resulting in low power, lower fuel economy and not generating enough vacuum to operate my cruise control.
 
Ok, pegged to the right, meaning the needle touching the peg?

The last couple of times I filled up, I filled it past the full "line", and the needle was pointing to the top-left corner of the letter "F". I'm very cautious not to overfill, due to the warnings regarding the California emission stuff, and not wanting to suck fuel into the charcoal filter.

I'll also try your suggestion of pausing, and squeezing in a bit more.

Thanks!
 
I also see about 100 miles or so before the gauge moves.

As for the dummy light. I think I read there is some calibration that can be done on them. When it comes on I get gas when I have a chance. 99.9% of my miles are commuting and it is 26 miles each way. Once I did about 75 miles with the dummy light on. I never ran out of gas but I am sure I was close. I don't remember how much I put in it. That was several years ago.

Yes - touching the peg (I actually went out and checked mine to be sure).

I admit I'm not an expert in the operation of the charcoal canister, but I do believe you'd have to fill the tank to very near the top of the neck before you'd need to worry about that.

If I DONT get 100 miles before the fuel needle moves, I know I'm not gonna have very good gas mileage for that tank. A "good" tank and it'll be 120 or so. 200 at 1/2 tank indicated is also another good sign, and 290 before LFWL comes on and I done good.
 
Hi all, recently joined here as some of you may know from my post in the Introductions section. :biker:

Just thought I’d share my gas/petrol mileage experiences on my ’94 ST1100-R here in the UK.

Earlier in the week the fuel warning light came on as I was on the way home from work. The gauge caught me out with how rapidly it drops in the lower end of the scale – something I realise is not uncommon from searching through the forum’s older posts! I filled her up to just below the filler cap level whilst sitting on the bike and she took 20 litres (?22 !!).

Unsurprisingly, the fuel gauge went past the full mark and off the scale, where it then sat for almost 100 miles without moving.

Then, yesterday at 145 miles we were showing half a tank full. :confused:

Today at 170 miles we were showing a quarter full, then after 185 miles we were nearing the empty line. Tonight after the journey home from work I fully expect the light to be on again somewhere in the region of 220 miles total. (My journey is roughly 30 mins motorway/highway and 30 mins gridlocked London city riding).

The fuel gauge is a joke so I’ve taken to using the trip-meter as a guide.

[Carl]: The gauge is not so much as joke as a commentary. :)
Thanks to the laws of aerodynamics, the fuel needed to push you over a given distance rises rapidly with your velocity. ;)
Thus, your trip-meter can deceive you as humorsly as your fuel gauge. :p:

Maybe your Parliament has passed different laws on your side of the pond. :D
But, over here, there is a vast difference in fuel consumption twixt blasting over the Great Plains and twiddling over the Blue Ridge Parkway. :D
Use both and some common sense as to the distance to your next fuel source. :cool:

:D Yep I agree, (hence I said as a guide) and using both in combination works quite well. (By the way high-speed runs really gobble up the juice!)

I find it very un-Honda to make such a reliable and trustworthy steed have such a non-linear fuel gauge. :confused: Perhaps the fuel level sender design was created on a Friday afternoon after several cups of saki. :D ;)

I'm planning on letting it run down until it is in the red. The owner's manual shows approximately how much fuel is left when the gauge is in the red, so that may give me a better idea.

After the yellow (low fuel) light comes on, there is an additional red warning light or is he just referring to the red on the gauge?
 
Wow, those new motorcycles.

I don't have a yellow low fuel warning, I have a red. The owners manual says about 1 gallon, and mine is pretty close, about 1.3 is my best guess. That's 1 and a third, not one and three quarts:)
 
Like clockwork my warning light comes on at 285 miles, The most miles I've been is about 336, I don't know why but for 2 tanks in a row I got over 300 miles before the light even came on?? anyway that's my 2 cents!!!!!!!!!
 
Filled Tuesday, 307 miles 5.74 gal. 54 mpg on the long (220 mile) down hill ride from 9000 feet to about 1000 feet in the valley. I generally never get gas before 200 miles and have gone 353 miles with a little more than half a gallon left.
The gauge is not linear. Mine comes off "FULL" between 60-70 miles, HALF is 120-140 and hits the red arc at 220-230. Under normal circumstances it takes about 5.0 gal at that point. I don't worry about it too much. Under the worse conditions of wind, weather and terrain I know I can comfortably go 250+, no worries. It takes a lot of miles before the low light comes on after the gauge says empty. And, yes it will hold at least 7.4 gal depending how full you want to go.
 
The only time I got 42 mpg was in South Dakota with a 40 mph high wind, I usually get 50-55 if I keep it under 75mph. I fill it to the bottom of the neck and have put up to 6.7 gallons one time.
 
Maybe it is the gas served in Georgia but in the two years and 30,000 miles I have ridden around the panhandle of Florida and tracked my mileage (I record every tank), I get between 42-46. Most of my riding is 1-up 30 mile commute (max speeds 65-70 on a couple short stretches unless I am passing a logging truck) and longer 1 or 2-up weekend rides. I have never seen 50 MPG! What is the secret? Do you have one of those secret devices that the gas companies and car companies don't want us to know about?
However, my wife's Suzuki 450 twin cylinder gets 50-55.
 
Interested to read this. I am finding on my ST11 that i am lucky if i get 200 miles before the light comes on when doing my commute as it is only about 5-10 mins each way. I did do a big ride the weekend before last and the light didn't come on until 240 miles which is more like what i was wanting. My previous Africa Twin would give me the same miles whether commuting, riding slow or riding fast. Seems i have to be easier with the ST.
 
I had an anomoly on Sunday. Filled up at Bernalillo, NM and headed east with Aulia, stopped in Las Vegas at ~150 miles. Took off for more east and north without really thinking about it. 180 miles later I finally found gas again in Clayton, NM. With 331 miles on the odo, she took just shy of 7 gallons for a return of 47 MPG. I've been getting 40/42 so am very happy for the constant tail wind.

I went thru 3 recognizable towns between Las Vegas and Clayton with no sign of a working gas station. Very remote state roads, too, with very little traffic until I got onto 385 pointed north toward Clayton.

Next tank was against a quartering head wind, she got right at 40 MPG on that tank.
