OK I did a search and can't find any thread on this.

I've refilled 3 times as soon as the fuel light comes on and each time it has taken spot on 12 litres. Magazine tests state the F3 tank holds 16L but my Owners manual states 17 litres?

I now want to find out is the manual accurate in stating you have 4 litres remaining from the warning light. And does the uptake actually let you use those last few drops?

So far running in I got 230km until the light. More recently I get about 200 under harder riding obviously.

So lets hear how far people have gone on a tank and how many litres it's taken from empty
Cheers

Glad you asked the question, MV. I was paranoid after a hard ride yesterday about mileage and getting to a gas station. So far I have gotten about 40 MPG...is that about 62 km/liter? - not sure if my math is right on that.

I've run to the warning light two times now and went another 10 miles (6.2 km) both times but didn't push it any further than that.

When the warning light comes on, it looks like some "fuel range" display comes up - but I see nothing in the manual about it. Yesterday the number increased as I rode more on the yellow, which confused me.

Hi MVNoob.
Yes a fuel counter starts when the orange 'low fuel' light comes on and counts up from there. Personally I prefer that. My Tiger and before that my Daytona 675 countered down once the fuel warning kicked in. Triumph's count down to zero estimate was too conservative by about 50km (30 miles). The D675 would go warning at about 220km and I could get another 60km from there = total range of 280km normal road riding, Ok quite fast riding. Track days was a different story of course.

You getting 40pmg (US gallons, not imperial I assume) equals 17 km/litre. I got 19km/l when running in below 6,000 revs but now it's done the 1,000km I got it down to 14 km/l

I hope the F3 will also give me at least 250km (156 miles) a tank as I do regular long trips away over summer and gas stations are few in remote places in New Zealand's deep south.

I'm going to carry a bottle and run it dry I think to find out exactly how much useable fuel there is.

I got about 35miles/gallon (14.88kpl) when riding hard (10k-14k rpm in 2nd gear).

I'm thinking the counter might be an estimate of fuel used, as it increases while riding. Not sure what the units might be, but maybe still metric even though the rest of the dash is English. I'll have to watch it closely next time and see if the math makes sense. One note of caution for you MV in NZ: Running the tank dry may not be a good idea for the fuel pump as most injection pumps depend on the fuel for cooling. Run the fuel too low and you might heat-damage the pump - not good.

i've never bothered to check accurately my consumption figures , but within about 10 miles or so of the fuel warning light coming on i fill to the brim and from then i get about 100 miles on average .

Holly crap on a cracker, 230 klm’s? The first time I saw my light I’d only gone approximately 170 klm’s. The second time I had tried to be more conservative but traveled only 186 klm’s. I have noticed something though, my bike doesn’t roll down hills. This past weekend I pulled the clutch in at the top of a long, steep hill to see how fast I’d pick up speed but to my amazement I began to slow down, rather quickly too. I tried it several times and each time the same result. Almost as if I was lightly dragging one of the brakes.
It’s hard to tell just by spinning the wheels, the rear has so much drag due to the chain. However, the front doesn’t spin as easily as I’d like. It doesn't appear to be due to brake drag, I don’t think. Maybe it just needs more break in time? I have had to clean up a lot of excess grease from the front bearings. Maybe they over packed mine?

Are you serious. We run minimum fuel in our bikes all the time, especially when just testing something, sometimes just 3 or 4 litres, never had any problems.
I cut the low fuel light wire, because it will come on during a race and irritate me.
I can respect what your saying but I honestly don't think running low on fuel, now and again, will damage anything, after-all, how long can you go on a low fuel level.

Was that with the bike running or was it switched off ? That sounds quite unusual to me.
They don't pack front wheel bearings mate, sealed from the factory, if I was you I would quickly remove the brake pads or calipers, and spin the front wheel, 5 min job.

48km after the light comes on seems to be my limit of easy riding. I can not comment on range with the tank full as my riding style uses power consistently.

I have run the bike out of fuel, pushed it 1km to the fuel pump, filled up, turned the key and started the bike finishing my 350km ride with no issues.

I reckon more likely to be clutch drag. Whack it on a rear stand and see how much there is with the engine off in gear. The ride by wire might be hiding it by trying to keep the engine at standstill, i.e. Clutch in and little/no throttle opening.

Meaning either poorly adjusted or needs some bedding in. I've experienced this with fitting barnett clutches in older race bikes.

Pure speculation on my part tho.

Thanks for the input Donsy - I've seen this happen more than once on the automotive side, but I'm pretty new in the motorcycle world so there are probably many automotive failure modes that don't transfer directly to motorcycles. I probably shouldn't have said "low fuel" either. Automotive fuel pumps fail when the tank is run dry, not low. The failures happen very quickly though, usually with the pump motor melting down.

Still no word from anyone on exactly how much it takes to fill from empty. Well I did 249km last night taking 14.5 L to refill. Light came on at 208 so now I know 40km on reserve is OK. When filling I tried to look inside the tank and could see about 2 inches maybe at the bottom, but I couldn't see the section under the seat.
So I'm still guessing it will take 16 L , which means for me 270km tank range is possible and that's good news.

The final word. 15.5 litres tank capacity

Sputtered into the gas station today after doing 266km on a tank with the engine conking out. Not hard riding.
Listening to the tank with lid open as I shock the bike and not a sound of any splashing petrol so I believe I totally ran it dry. Took exactly 15.5 L to the brim. Reserve light came on at 208km

So for you Yanks thats 166 miles from a tank and 4.09 US gallons or 3.4 imp. gallons. .

Thanks, that sounds right. Every time I have been filling 3.5 US gall after my reserve light goes off.

Anyone figured out what the bizarre count-up is yet?

Fucking freaked me out the first time it came on yesterday. I was waiting for a message to say "YOU HAVE TWENTY SECONDS TO REFUEL YOUR MOTORCYCLE OR YOU'LL DIE!!!!"

If it reaches 60 the bike self destructs because the rider is an idiot for not refuelling.

The counting up from the low fuel point is far better than the traditional counting backwards. Counting down assumes the estimated starting point is accurate.
