Firstly Mr Tweetytek, thanks so much for the 'how to check your mileage 101', I'm sure if I was some pimply youth on my first bike I would find that invaluable, but I'm 51, been riding since I was 16, and know how to check my fuel consumption. I wasn't using the gauge to check, merely saying that I had gas left in the tank so expected quite a few more miles to my tankful.
I have recently become aware of fuelly, but TBH life's too short for that sort of thing, I'd rather be out riding.
Lastly my first tankful was to see how much I could get if I rode like a granny on my commute, I managed 260.3 miles and used 19.17 litres.
You do the math and I don't care if you don't believe people get that kind of mileage. The second tankful will be to see how drastically it changes if I ride like a hooly, and I must say I'm enjoying it a lot more!
I wouldn't have a clue what my fuel consumption is on my bike, i do know when the bike's not performing right though so i doubt it would catch me out.
Bearing in mind i have to give myself 35 minutes on a normal day to travel 5.5 miles to work which is near the A40, but if the A40 gets clogged up at all the traffic can start all the way back to my house!
I rarely let the tank go less than a third full anyway, just in case i get caught out in bad traffic near my work.
It's been so bad before that i have been trapped in a side road and had to ride slowly on the pavement the whole length of a street to attempt to get out of it.
Another common one is traffic lights stuck on red which has happened a few times, causing more gridlock.
In those circumstances, which can happen quite frequently, fuel consumption becomes totally irrelevant.

What happened to the other 3 litres?

Super! Were the same age then, But your never too old to do a little simple math! or too young in our case
To be serious tho, what you have said comes over to me that everyone had a preferred way of doing things and we do what we feel comfortable with.. So it's refreshing to hear that you have find your own method that suits you.
to be brutally honest, I don't give a hoot what Mpg I or others achieve, life's too short and I worry about other meaningful matters.
Good on you and enjoy the ride...
It's all about frredom and fun.

I find this graph very useful for calculating mpg. It takes into account solo and pillion rides, mirrors folded or extended (mirror area req.), weight, food intake, jacket floppiness, insect/bug impact, touring or crouched position, arm thickness and size of helmet to extract a true mpg exponent figure............
Those are my principles...if you don't like them I have others.

I use an app (android) called Fuelio. Been using it religiously since I bought the fazer tracking both fuel and other expenses such as parts and tyres. Find it provides very useful information at a glance.
That is just some of the fuel stats, there's another 3 sections above it with more details. And then if you have been entering other costs like I have there is a seperate section for that.
It's handy, I take out my phone after I pay for the petrol and put in the details before I leave the station. No websites to be going to, no spreadsheets to be updating. You can even let it track where you get the fuel by GPS or add notes to the fill up so you know what stations are putting out piss for petrol. Get significantly worse fuel economy from one particular station? Don't go back!
edit: I've not been on the bike since May practically due to a broken finger so those stats are from Jan-May, and yes I only use about €40 petrol a month.

Maybe, but a logrithmic coefficient would yield a more intrinsic constant :lol

What about prevailing wind speed & direction,ambient temperature,relative humidity, tyre brand/tread pattern and tyre pressures. And bike clean/polished or filthy dirty? :lol

Im gonna try and break 300 miles to a tank. Im gonna brim it to the max with super unleaded then ride like mary poppins on valium. Anyone want to sponser me !!!! :lol

It's easily possible to do 300 miles on a tank. I did 74 mpg on my last boxeye once, but it was probably the most boring ride ever!
I set off in 1st, then change up to 3rd, then into top gear. Feathered the throttle to accelerate, rolled off very early before I needed to stop, and kept below 55 mph.
Got a feeling you'll be running on fumes though when you hit 300. (unless your on a Foxeye)
I've been regularly getting 260 miles to the tank, usually then takes 19l to (seriously) brim it meaning there must be a few more miles left on reserve. I expect mileage will start dropping soon as the temps drop though.

Arbie, in order to assist you with this scientific research may I suggest the following which I found very useful:
1) Chop off the front section of a pair of the wifes stilletos and attach to front of boots to aid aerodynamics (white patent leather is very slippery).
2) The use of stockings (70-99 dernier in beige) are essential aids for application to the legs and arms to reduce clothing flappy/floppiness.
In addition, tights with the legs cut off should be applied to your torso (70-99 dernier Red).
3) A traffic cone attached to the rear of your helmet provides an additional 3.196% reduction in drag factor (DRAG effect negated by the use of blatant drag queen stockings).
4) Inflate the tyres to approximately 58.45073 Psi front and back.
Good luck fella, may the force be with you :thumbup
Those are my principles...if you don't like them I have others.
Cheers frosties im gonna do just that. Except for the missus stilletoes....my nads look nice where they are thanks !!! Ill have to sacrifice a pair of my own
(08-09-14, 09:53 PM)tweetytek link Wrote: You cannot work out a reasonably decent MPG figure this way - i.e., looking at the needle .
A better way is to fill up at the station and make sure you insert the nozzle so that the handle is facing 12'o clock to 6'o clock, i.e. down the tank.
1. Stop at the station , Fill the tank up until the pressure valve in the nozzle stops fuel. Keep trying with pauses. Keep clicking that nozzle until not a drop more fuel can go in. Now ride your bike until nearly on empty
2. Reset your odometer trip counter; repeat (1) above AT THE SAME PUMP you used before; keep the receipt showing Litres used and total cost; write the trip counter value on the receipt; then repeat 1 above; take a note of the new trip counter and write this on the receipt.
3. Repeat 2
4. Now, for the two receipts , work out the MPG FOR EACH as follows:-
a) divide the number of litres by 4.5 - the number of litres is on the receipt - this gives you Gallons of fuel.
b) subtract the lower trip counter from the higher trip counter; this gives you Miles travelled
c) calculate MPG by dividing Miles travelled (b) by Gallons (a)
Simple math mixed with some stable test conditions, as stable as you can reasonably get, but I thought it may be of some help ??
This is basically what sites like "Fuelly" does but the above method does not require you to sign up to a site and get spammed via email as they sell your email address on - come on, you dont think you get something for free in this world do you
FIW , my average is 48MPG used on a 22 mile round trip commute, 5 days a week, 9 months of the year, on A, B and unclassified roads, same journey every time, 11 sets of lights on the journey so some stopping/standing. Rather sceptical of the claimed 65+ MPG I've seen touted , but hey if people want to claim it, why not ! what do I care
How about calculate MPL then multiply by 4.546092 for MPG.
Personally I'm liking the simplistic idea of fuely doing the job for me
Women have chocolate men have bikes.....
including ones who like chocolate....
Yes, I can see how the math is taxing :rolleyes
One still has to record figures / transpose receipt data into fully anyway, log on, upload data...
One man's easy is another mans headache
Great that there are so many ways to accomplish tasks, anyway I'm off to bed
:z
or too young in our case
