Running out of gas

To test the miles after reserve, I thought to carry a 2 ltr canister.

Can anybody tell me if running dry could cause engine issues?

Shouldn't be an issue. As soon as you notice the engin stalling, clinch the clutch and steer towards somewhere safely.

I happened to run the bike completly out of fuel, from the first signes until the engine died I travelled about 1.5 KM (throwing the bike from side to side) and just made it to a station.

No issues what so ever after the incident. I'v put about 5000 KM after it happened.

So do we have a full usable 6 gallons ? Yesterday I stopped for gas just after the low fuel waring came on and it took 4.4 gallons to fill to the baffle. The most I have put in was 5.1 gallons and that was riding about 30 miles after the low warning light came on. I have 2500 miles on it now and the fuel mileage is averaging in the upper 40's, the last 2 tanks were 50.2 and 50.5, non interstate riding. The low fuel light came on at 217 miles and 222.

I'm curious how much fuel it actually holds, never put in over 5.2 gallons.

No problem if it happens on occasion, but done regularly it will tear up your fuel pump.


It'd be great to know what you learn.

46 miles into "reserve" and took 5.4 gallons over the weekend. That's good to know.

Talking about gas, I noticed the manual for the US bike says its fuel consumption meter reads in imp. miles per gallon and not US miles per gallon. Interesting.......

You are correct, that is what the owners manual says (page 4-11), but I believe it is a typo ???

Is there a difference between Imp. miles and US miles? I think not.. But there is a difference between Imp gallon and US gallon.

an imperial gallon is approximately 20% bigger, my calculations have always been within 1mpg, U.S. of the trip computer. living on the u.s./can border, I fill up on both sides frequently.
my concern is with running a fuel tank dry. I had heard that the gas is what cools the fuel pump, and to try to never run out of gas. any truth to this? anyone??

As someone else said, you don't want to do it routinely, but I wouldn't worry if it happens a time or two. This is one of those things that probably gets more worry than it deserves.

It would be nice for someone to really see if we have six-gallons usable capacity or not. The anecdotal evidence seems to be piling up that perhaps we don't.

Well dang, I just filled up. Could have run out real easy last night.... was about 40 miles into the empty count.

I agree, when mine goes to the empty indication it takes 4.4 US gallons to fill it. The manual says I have 1.0 gallons left at that point. The manual also says I have 6.08 (6.1) gallon tank. Something does not add up.

FWIW, I was 36 miles into "reserve" and it took 5.6 to fill up.

Yes, the pregnant question is whether we have a 6.0 gal capacity with a 1.6 gal reserve or a 5.4 gallon capacity with a 1.0 gal reserve. I suspect Yamaha fudged both the numbers a bit so we probably have a 5.8 gal capacity with a 1.4 gal reserve. Ideally, someone will test this out. Or at least we'll get enough data to establish a high-water mark over time about how much fuel can be put in after running it low.

I ran mine from full to 205 miles this past weekend and filled up (to the bottom of the filler neck), on the side stand (level ground). It took 5.04 gallons. Based on that, I figure I've got another "for sure", 30 miles left on the tank, even if I have to go into a "fuel conserving", riding mode. This was 100% level grade, one up, slab riding at 80 mph average per my Nuvi 500 GPS. "Touring" mode was set, with MicaTech side cases, Givi E36 top case, Calsci medium screen and a 60% touring load (for me, and I load heavy), on board. Wind was crossing at about 90 degrees, 15 to 30, with gusts on the Skyway at close to 45-50, or better. There isn't a windscreen in the world that's going to prevent that kind of helmet buffeting! :D

I'm figuring the bike will do 200 miles per tank, in just about any topography/road quality/riding style I'll ever use it for. I always keep a close eye on the trip set odometer anyway. A couple of 1 liter MSR fuel bottles and a siphon hose on long trips gives peace of mind. Only had to use the spare fuel once on an unexpectedly long, country road detour in central MO, a few years ago with my DL 1000. The bike went bone dry at 220 miles. Just 10 short of a #$%^&*, gas station!

As it breaks in further, and going to synthetic oil at 5K miles or so, I'm hoping to see close to 45 mpg with this bike. ::001::

Maybe a bare S10, with a good screen could get close to the "Holy Grail" of 50 mpg. I did it once on my "unbagged", '02 R1150 RT, but that bike was one "slippery fish". :D

I was the one who wrote that fuel pumps don't like to be run dry, and yes the reason is because they are fuel cooled.


As for volume, the tank has a large expansion space at the top which isnot very usable. You have to work to get tha t last gallon into the top expansion space. Next time you fill up, notice at what point the pump stops. Then keep filling the neck until it really stops. The difference is pretty large.

I really find that tank 'insert' really annoying, making fillups a real pain. Never had a bike with that before. Just may have to remove it. I wonder what the fuel dripping out of the vent lines will be like then!

My Ford diesel has the same thing....for some reason Ford did not want you to use the fuel pumps as a truck stop; the truck stop pumps have a larger OD nozzle and flow much more fuel than a 'regular automitive' diesel pump. Not to much of a problem if you have a small tank, but my main tank held almost 40 gallons and my in-bed tank held almost 60.

I wouldn't take the insert out, as it provides an expansion space. The volume of gasoline can change pretty rapidly with changes in temperature. Without the expansion space, the next softest thing would probably be the shape of the tank, the gasket for the pump, or even the pump housing.
