• Hi everyone,

    As you all know, Coffee (Dean) passed away a couple of years ago. I am Dean's ex-wife's husband and happen to have spent my career in tech. Over the years, I occasionally helped Dean with various tech issues.

    When he passed, I worked with his kids to gather the necessary credentials to keep this site running. Since then (and for however long they worked with Coffee), Woodschick and Dirtdame have been maintaining the site and covering the costs. Without their hard work and financial support, CafeHusky would have been lost.

    Over the past couple of weeks, I’ve been working to migrate the site to a free cloud compute instance so that Woodschick and Dirtdame no longer have to fund it. At the same time, I’ve updated the site to a current version of XenForo (the discussion software it runs on). The previous version was outdated and no longer supported.

    Unfortunately, the new software version doesn’t support importing the old site’s styles, so for now, you’ll see the XenForo default style. This may change over time.

    Coffee didn’t document the work he did on the site, so I’ve been digging through the old setup to understand how everything was running. There may still be things I’ve missed. One known issue is that email functionality is not yet working on the new site, but I hope to resolve this over time.

    Thanks for your patience and support!

Have you ever run out of fuel? (TR650 question)

Curious. Have any TR650 owners run out of fuel?

I am tempted to try to see how many miles my TR650 would go after the low fuel light came on, but thought someone else may have already done that test.
 
I've put a few tanks thru it this weekend....getting a steady 61mpg. I'd be curious to know how close to the claimed 3.7 gallons the tank holds.
I'm not a big fan of running EFI bikes out of gas though - so let us know what you find :D
 
I Haven't run it dry, but I have put 13.7 litres in (that's 3.6 US gallons) and it was still running.
 
I normally do this with all my bikes just to see what my true range is. However, with that handy dandy little fuel consumed function, it never even occurred to me to try on this one. Hmmmm.....I must do this.
 
I've had three fill ups in a row at 350km each time taking 14l, with no sign of running out. Getting a little nervous though !
 
I just spent most of the last week in the saddle of my Terra. Most of it was pavement at 50 to 2000 ft. elevation, and included hundreds of miles on the Interstate at 70 to 80 mph sustained. On the way home I ran 70 mph into a constant 20 to 25mph headwind. Some dual sport dirtyness was thrown in for good measure, but way too little for the miles ridden. My fuel consumption varied from 44 mpg to 55 mpg. I never ran the bike dry, but found that the fuel consumption indicated matched very closely to the fuel put into the tank.

fuel pumps are cooled by the gas they're immersed in....running the tank dry on an injected bike runs a risk of frying the pump

How would a bike with submersed fuel pump differ from a car/truck with a submersed fuel pump?

I'm sure that you could get away with running it dry once without seriously damageing anything but pumps don't like to be run dry for any lenght of time, regardless if it's a car/truck or motorcycle. I wouldn't make a habit of doing it because it does take it's toll on the rotors/turbines in the pump.

At some point someone is going to run out of fuel, it happens. I don't think anyone would want to make a habit of doing that.

Yes I understand that sometime, somewhere, someone is going to run out of gas. The point that I was trying to make was that it puts undue wear on the fuel pump so I don't recomend intentionally doing it.

Understood. However...

At some point someone, possibly myself, will see the low fuel light come on and think OMG I am on a long road with spotty cell phone coverage! I know what parts of the road have cell phone coverage though. At that moment it might be nice to know if I could reach the gas station, or I need to pull over and call a friend to bring fuel.

What I do not want to have happen, is to actually run out of fuel on the part of the road with no cell phone coverage. Especially if it is a road that has little traffic (long walk).
 
Today at 141 miles my fuel light came on. I made it to a station at 149.6 miles. It took 3.23 gallons. It coughed as I was pulling into the pump but did not die. Most of the miles were at 65 to 75 mph in strong head winds. 49 mpg is not bad but I hope for more once its broke in.
 
I burned up my CBR fuel pump when I ran dry during a track day at Mid-Ohio. Have also gotten away w/ it on several occasions.

About 30. Bought my bike on a Thursday, rode it to work that night, failed to note that light came on after leaving in the morning, oops. Come to find out that the dealer only puts in 2 gallons at sale, and neglected to tell me that when I picked up the bike, so I got to sit on the side of the highway for a bit while my buddy brought me some gas.

Interesting! Thank you for your input. :thumbsup:

My bike was filled to the brim, then the low fuel light came on 163 miles later, and finally got to a gas station 27 miles later (after the low fuel light came on), and it took 3.5 Gallons to fill up. So the total range 190ish miles? I will continue to keep tabs on this topic...

Anyone else?

My consumption also matched to the 1oth of the gallon on all fill ups. Love that.
 
I've seen same accuracy between fuel consumed and fuel filled. But we don't know if all the fuel in the tank (4.2 gallons or whatever it was supposed to be....I forget) is useable.

Next opportunity I have to "run her dry", I'll give it a go. I'm not skeeeered! I'll strap on a rotopax and won't stop till she dies.

We got to know the ultimate range, folks. No more "tapping out"

Correct.

Nor do we know the variability between bikes, nor do we know if going uphill, flat, downhill is more prone to running out of fuel.

I continue to experiment and will present data later, but the farthest I've gone is 27 miles on the odo after the low fuel light comes on, and did not run out of fuel.
