Reading therough the threads last night and looking at the one in particular that mentioned the early 08s as being able to remember which ODIS display you were using from ride to ride I decided I would look in the manual to see if it mentioned it (it doesn't)

What it did mention, and I'd obviously missed before is the method to reset the average MPG and more importantly (for me) that it was possible to set the display to MGPI (miles per gallon Imperial).

Now obviously this is really only of use if you are in the UK (as I am) but those two things were a bit of a revalation for me. (I know I should have RTFM properly before!)

Firstly it shows I am actually achieving an average of 35MPG (Imperial) which is significantly better than (a) I thought and (b) I expected.

I realise this is old news to most of you but it's really nice to be able to reset the average MPG display... I should've read the manual better earlier!

Knowing I am getting 35MPGI out of a bike that I commute to work on and cane the tits off is really nice. My old TL only manage 25MPGI and my ZX9R is only managing 30.

I know fuel economy is one of "those" topics and I absolutely bow down to the likes of Froggy in those stakes but as I had previously been looking at a MGP (US Gallons) display this is a big improvement for me!

LOL

I cannot fathom someone who would pay many thousands of dollars for and operate a vehicle which literally puts their life at risk if operated or maintained incorrectly NOT reading the manual.

RTFM!

Oh behave... I read the important bits if you think not knowing how to reset the average MPG setting puts lifes at risk then god help you...

Resetting the tripometer and average fuel economy are the two most important functions in my book! I don't give a damn about the rest. (Although the warranty fine print can save your bacon if you have a stubborn dealer)

What is lame is you can't set it to display speed in kilometers and fuel economy in US MPG at the same time. Perhaps I should try the imperial miles per gallon, so it really looks great. My 48mpg US on my R would be 57mpg imperial.

It's a pity you can't mix and match displays, I'd like to have the Gear display and battery voltage together sometimes, othertimes I'd like instantaneous MPG and battery voltage... Sometimes IAT and CT..

Guess that's a lot to ask though really LOL, i guess I'm greedy.

57MPG (Imperial) LMAO, seriously that is impressive stuff, my hat is off sir!

I've also wanted voltage and instant fuel economy. I am sure it can be done if you hacked the instrument cluster.

Jules: I'm just giving you a hard time mate. Cheers.


I've often wanted to see all the info at once.
I believe there's enough room on the display to show:

V13.8 G 6
C209F A102F


Or maybe:

A 39C G 6
C 98C V13.8

i must have read the manual for my CR, but so long ago ive forgotten. before i even rode the bike i set my units to imperial (yes, another damn brit!).
i am actually getting 43mpg (Imperial of course!!), and i cant actually get it any lower even if i try harder lol.

i dont use the gear indicator much, but it seems to default to that every time i switch off, so have to set it to temp (in Centigrade)/volts, after each fuel stop/food break.

i prefer that anyway as i can keep an eye out in case anything goes wrong

(and then forget everything about how to work it on the track )

Worst I've ever got riding my bike on the street is 28 MPG US (33.6 MPG UK) and that's being a total hooligan with lots of wheelies and blasts over 150 MPH.

Best I ever got was 48 MPG US (57.6 MPG UK) while drafting a semi truck trailer through the Nevada desert (Hwy 95) at night. No joke.

I Averaged 17 MPG US (20.4 MPG UK) during my recent track-day.

Here's a Fuel Consumption Calculator.

@Stimbrell.

i wonder if its accurate. i just reset it occasionally, not every fill up. i might run a proper check if i can be bothered.

the best mileage from one tank so far has been 175 miles with the warning light on for 20 of those miles.

I reset it today and went out for the day, checked when I got home and 27mpg (imp). I have a stage 2 Sportster which runs way less mpg than others with similar builds, coming up to 3,500 miles on my 1125 the second rear tyre is almost done as is the original front. I just enjoy myself too much, my fault not the bikes. Not bad for a nearly 50 year old guy I think, I am certainly not going to worry about it. Enjoying myself way too much.

Actually, it's not.

I had been having doubts about that lately, so I began tracking the relevant information.

I have compiled the results in the following spreadsheet:
Buell 1125R Fuel Economy Survey


quote:

the best mileage from one tank so far has been 175 miles with the warning light on for 20 of those miles.



Best mileage I got was 190 miles before the light even came on. Filled up very soon after that. This was during my recent trip to Southern California and was 100% highway cruising miles.

That's the great thing about fuel economy, the main limiting factor is generally the rider.

I'm VERY happy with my 35MPG(I) as that's far better than I expected... but then again I do ride like a complete !

That 57MPG(I) I managed on a run to a rally with some friends on trikes does prove the bike is capable of it... It's just me that isn't!

..Wait until you find out how to work the lap timer!

Bloody Hell - I'd forgotten it has one of them!

just got back from a ride. the fuel light came on 200 yards from home after a 150 mile ride. still averaging 43mpg (imp)! i dont like having the bike parked in the garage with a full tank, so will check the actual mpg next time im out.

as for the lap timer, well 150 miles in 4 hours that included coffee break, nature break (twice, damn coffee), and photos.

in 4 hours?

I find the MPG to be pretty accurate. I reset it whenever I fill up. The low fuel light comes on when I've used 4 gallons +/- 0.1 gallons. And of course, you should correct for the speedo error, which is about 5% (it reads high).
I got 48MPG on one tank, riding with a group of Harleys,of course, at altitude. Mostly, I get 33.

I also reset the Average MPG after every fill-up. I do so at the same time I reset the trip meter, after getting my gloves on, before I start the bike.

I would say the Average MPG accuracy is acceptable, but it's not at all "dead on".

I have observed, based on tracking the mile posts vs. my odometer, that for every 31 miles the bike says I have traveled I have actually traveled only 30 miles.
Therefore, the 60,000 miles on my odometer is actually only 58,000.
