What does a 6 gal fill look like?

[holligl]

Recently pushed almost to the point of running out, but got to the station and filled with 5.3 gallons. Fueling this bike full requires patience as the fuel keeps "settling". Have you ever run out and added a full 6 gallons? How far up on the baffle does the fuel go when it's on the centerstand and at the limit?

I know you should leave room for expansion, but if you are riding immediately and wanting maximimum range, it would be good to know what FULL really looks like.

Well, technically, you weren't. I filled today at 220 mi. Put in 5.2gal. (42.3mpg) Theoretically, I could have made it to 254mi and put 6gal in. But like you, I want no part of running out. And since we don't know for a fact what mileage we are averaging, we can't depend on 42mpg in case we're only getting 41mpg and will be empty at 246mi. So, "I" will never know what a 6gal fill up will look like. Too many variables for me. (and it's not good for the fuel pump)

Pushed it on this one.

Next time you do that, can you take a picture of how high it is on the baffle? That's pretty good mileage! I did notice in CO last week, the elevation really helps the mileage, and reduces the power. Trail riding is way better than high speed hi way.

Forgot to fill up before leaving work one day. I had a 46 mile commute each way. There’s a stretch of no service where I noticed the gauge. I figured I could run out of fuel turning back or just press on. The latter choice meant that my wife wouldn’t have to drive as far to bring me the lawn mower gas. To my surprise I made it into town, pulled up to the first pump I could and shut off the engine normally. Amazingly, it took 6.1 gallons, which is the rated capacity on the spec sheet! Must have absolutely been on my last drop of fuel. The trip odometer was showing 340 something miles on that tank.

Funny you should ask! While going to Alaska and me getting lower mileage I kept filling until it was full. Then one time we didn't take off right away and Cycledude turns around... Hey Guy, You have something dripping from your bike... ahhhhhh, gas was dripping out of the vent hose. It was hot out around 95 somewhere in South Dakota. Hopped on the bike and we stopped around 150 miles down the road. No more dripping gas. So you can keep filling it up until it is right up to the rim. Usually when you get a pump that just lets you keep trickling the gas in so the air has time to escape out of the vent... which is immediately to the back of the filler opening with a rubber gasket. As the cap comes down it closes and seals on the vent. It vents up through the cap.
Shortly after I got home I stretched it to far as I made it home but then had to get to town and forgot that I had barely made it home. Luckily I got to town and filled it up with 6.145 gallons... to the rim. Then went off to ride before it could expand out the vent.

What was the altitude? ish.

I'm taking the opportunity of this thread to ask a related question: what happens when an injected bike runs out of gas ? The Tenere is my first, and it has not happened to me (not that I intend it to !).
Do you get the few seconds' warning a carbureted bike gives (time enough to switch to reserve or get clear of traffic), or does it cut out instantly and try to kill you ?
Not knowing, I never had the nerve to run the tank dry, even when carrying extra fuel.

It happened to me once and I did get a little warning, kinda like a carb bike. Very bad for the fuel pump though. The pump is not made to cavitate and it needs fuel for cooling. It is actually kept cool by fuel running THROUGH it, not by bathing in it, so when it is run really low on fuel, it overheats mostly from intermittent starvation, which is what ultimately kills it.

This might be a good place for someone who has done it to post a picture of a punch hole in the baffle (lets the air escape more easily). I've wanted to do that mod but leery of doing it wrong.

All right, thanks. I guess the ultimate range of a tankful is best left uninvestigated, then.

Not sure what you mean, this is a pic of a Euro Tenere tank filler neck. Plenty holes in the baffle. I remember some elaborate US pump nozzles sucking back the air escaping the tank, so maybe your
baffles are different over there ?

5.3 gallons is the farthest I’ve pushed it. Some of you really get the full use of a tank!

I have one on each side... would recommend more.

 

[Silver Badger]

I just like the fact that Mak 10 got 54 miles per gallon!

 

[Mak10]

I have done the hole mod, and would recommend more holes.

Trying to maintain 85 into a headwind with my boxes on.. I've gotten 28.

 

[gv550]

I punched 2 holes on high side when on the side stand.

Same as US. The mod is holes are punched higher on the neck to allow more air to escape other than the one small vent.

That's what I was expecting. At Higher altitude, the ECU maintains the proper fuel:air ratio, which reduces the fuel usage. Downside is HP is reduced also.

When I took my Jeep to AZ, 4500', I was getting 25mpg at 70mph. I normally average 16mpg at our 900' elevation.

I ran out about a month th ago... power weakened and then coughed and died. So, yeah... you get a real short warning similar to a carb but quicker. Hard on the fuel pump and injectors though. Put gas in it and it started right away.
