Fuel capacity

[Joesmoe]

My second (and most recent) fill -- so certainly not enough data to make any conclusions -- took 5.585 gallons after 169.2 miles of around town riding. i'm not sure how full it was when I started, so the 169 miles may have consumed less.

In any case, a lower limit has been set for distance/tank. If I can improve my riding style, and get better than 30 mpg, that would be a plus. Until I can afford a cruise control of some sort, a tank full will be a good interval to get off and stretch.

I said it before and I am going to say it again. Unless there are major differences between the 2005 model and the later touring versions, putting 6.3 gallons in the tank of a Rocket III is pure sci-fi to me and I'm going to tell you why.
The low fuel light on my 2005 comes on at about 109 miles. The first time it happened and being new to the Rocket I went straight into a gas station and filled up. To my surprise it only took between 3.5 and 4 gallons. "Knowing" that the tank capacity is 6.5 gallons I figured there were at least 2.5 - 3 gallons left in the tank.
Next time the low fuel light came on I choose to ignore it trying to accomplish what people like you have accomplished. 200 miles on a full tank of petrol. Guess what happened next? I ran out of fuel with 154 miles on the clock. When I refueled it only took 5 gallons which shows me that you don;t actually have 6.5 useable gallons. So if you don't, then how is possible to get even 180 miles out of a full tank? If when you refueled you were able to pump 6.3 gallons into it, it means you have an alternative energy source for your bike. That it runs on some s h i t you are not even aware of. Can someone explain that to me? How is it possible to get that many miles and put that much petrol in this bike?

I have a 2005 and the most I ever put in was 23.5 litres which is 6.2 US gallons. I usually fill to just over the bottom of the chromed thing when on a run to maximise distance.

I have a 2005 and my light comes on at 119-125 miles every time. When i put fuel in It only takes 3.5-4 gals.. recently I went on a ride and choose to ignore the light I stopped for fuel at 200.4 mile and added 5.8 gals.. I was running 75 mph with a friend on a Harley.. doing what he could to keep up.. I would love a fuel gauge but heard they are about as reliable as catching a fart in the wind... but would still me nice to have one.. not the fart..but the gauge

It all depends if you are talking US or Imperial Gallons ,also if you are using a accurate measuring device not the Junk shop kitchen measuring jug , made in some shonky Asian factory.

Ken..as I live in the USA..that would be U.S. gallons.. but hard to say as most of the service stations here are owned and ran by Indian/Pakistani .. I have also pulled in with half a tank of fuel and according to the dial on the pump I pumped 18 US Gals. into my 6.5 gal tank... when I confronted the clerk he said...oh it does that sometimes.. here's your money back..no need to call weights and measures.. I called them of course.. I ain't real smart but I can add and subtract..

And I am sure their cousins are running a lot of the fuel outlets in OZ.

Second full fill yesterday . . . ran the count-down to ten miles remaining . . . showing 200.0 miles on the trip odometer . . . tank took 5.484 gal US. Still too little data to draw firm conclusions. There is some indication there that the count-down in conservative, or similar to an airplane, they have to take into account that under certain conditions some fuel is unusable, so the limits are calculated from those so-called corner conditions.

Still, I'll take 36 mpg and 200 miles on a tank.

The economy will improve as the bike "runs in" my R3T was averaging 5.5 litres per 100klm roughly 42mpg US given that the US Gallon is 3.78541 litres and 100klms is almost 62.5 miles ,this has risen to 6.5 litres per 100klm after derestricting map and TORS and K7N filter , however the performance improvement is well worth the minimal economy loss.

So ... funny story....

My rocket had been turning on the light and showing 0 miles to empty at around 130 miles. It usually had 2 gallons left in the tank, so when my light came on yesterday morning I ignored it.

Today, at 160 miles, I got the privilege of pushing the rocket, uphill, for about a 1/2 mile to the gas station. She took 5.97 gallons of gas in a claimed 5.9 gallon tank

R3R_Slip Tune and a heavy hand yield 8.6 liters /100 km or 27.5mpg (US).

TL/DR: When making right hand turns, if the bike stalls, you are about 1 mile from being OUT of gas!

The thirstiest bike I ever saw was a H3 750cc Kawasaki 2 stroke triple, a bloke on one of these beasts came to Bathurst with us one year ,reverse cone expansion chambers bigger jets in the carbies foam pod filters a real screamer ,we had no chance of seeing where he went let alone catching him ,except at every service station, he ran out of petrol between Richmond and Lithgow about 40 miles on a full tank giving it full stick , it was drinking at the rate of 14 mpg Aus or 10.6 mpg US but I reckon if it had wings it could fly, he just wobbled around the corners and fired it up the straights a lot of time on the back wheel.
