Title: fuel consumption
Post by: Blubber on Friday, 10 March 2017, 01:00 AM
Hi Guys,

Just out of curiosity.. what kind of fuel consumption does your 14 have AND with what modifcation.

Mine is a K2
Stock cams, stock airbox
Full Akravopic system
PCV + autotune

A indicated 300KM is exactly 20 liter of Euro95 , so per liter I can run 15km under normal conditions ( commuting ) and using all 6 gears.
Consumption during Play time is different.  :devil:

So , my AVG is 1 liter : 15 KM's

I managed 429 all highway kms one day & a month later less than 200km at a track day. Average around 300/320km before I think about fuel on a town/country ride. That usually takes 17 to 18 litres of 91octane or E10 after that.

280 tops with a squeeky arse
250-260 I'm looking for fuel stops

I dont really take any interest in real mpg -  when empty fill, then ride :grin: :grin:

yoshi cams
pc3 (for now pcv on it's way)
pod filters
full acroprovic system
4°advancer

i regularly get 180 miles per tank but have pushed it past 200 miles per tank .
sitting at motorway speeds over in europe.

i notice if you can get a few more liters (up to 5lts) in the tank if you fill very carefully letting it settle and then adding a bit more fuel .

:cheers:

Thanks for all the replies so far.

So, It's perfectly normal for the 1st bar to go blinking around 280km. I haven't had 2 blinking thingies  :cool: must try harder / ignore longer :boogie:

I tend not to let it sit in 1 bar too long as a rule of thumb but can get about 170 miles before filling up - I have never actually looked at whats left after its starts to flash

327kms from full then put in 21.7litres.

Post by: froudy on Friday, 10 March 2017, 07:36 AM
I never take too much notice of MPG.
I do approx 140 miles and it costs me £17 to fill back up at £1.15 per litre..

So as the "septics" say..Do the math :lol:

42MPG...Caning it on the motorway isn't bad!!!

Bloody hell Col, you run it close.  Only takes 22L!

@Blubber


with 2 blinking / flashing thingies, that goes off once you're down to 1.75L left in the tank. The only issue is, you might not see it straight away & by the time you do notice, there's not 1.75L left at all, maybe only 1L!!

@Beaker   @lawrie   


That's the price for a Litre, not a gallon.  Depending on where I fill up & how empty it is, it'll cost $40 - $45 to fill up.     Wonder if diesel is an option??  Plane the head & replace sparkplugs for glow plugs . . .  There ya go Lawrie, something to really get yer teeth into

Title: Re: fuel consumption

Two flashing thingies?
Never seen that even when coughing due to lack of petrol....

I usu get around 270ks per tank mostly commuting.
Title: Re: fuel consumption
Post by: KiwiCol on Friday, 10 March 2017, 10:03 AM

@VladTepes


it's the last bar that blinks & the wee pic of the fuel pump above the last bar. These are the 2 things that flash.


If you not seen it, 1 of 3 things.  1, part of it isn't working,   2, you're not that low on fuel after all, or 3, you just never noticed.
Title: Re: fuel consumption
Post by: VladTepes on Friday, 10 March 2017, 10:26 AM
Oh yeah ive seen both blinking... is there a stage when only one does?
Title: Re: fuel consumption
Post by: KiwiCol on Friday, 10 March 2017, 10:38 AM


Yep, the fuel pump icon will flash when you're down to 6L in the tank. 
The fuel pump icon & the last bar will flash when you're down to 1.75L. 


Basically got between 25 & 30 k's left before you're walking once they both start.



The trick is to notice when they both start, not notice it after 10k & think you've still got 25 left.
Title: Re: fuel consumption

Cool thanks for that.  I'd never noticed just the pump flashing by itself but then I never really looked.....

Post by: Mick_J on Friday, 10 March 2017, 06:36 PM
I get about 50 miles to the gallon, hardly ever get down to anything flashing as I fill up whatever I've used every time I ride, always park it on a full tank.
Title: Re: fuel consumption

Hell, to get 50mpg I gotta ride 'very sedate' I mean hardly crack the throttle at all.

Post by: froudy on Friday, 10 March 2017, 08:20 PM
I did do 160 miles once while hunting for a petrol station to fill up and was getting nervous :grin:

My commute is 35 miles each way so I do two days (140 miles) then fill up on the way home. Ride my last shift as I do three shifts per week and then fill up again after 70 miles, so I'm ready to go again the following week with a full tank.

As mjgt said I always park up with a full tank too.It helps prevent condensation forming in the tank in the winter if it's parked up for a few days :onya:

It's nice you look after the fat slug. Treat her nice n she'll be with you for years n years, actually, she'll probably outlast me & you.   But cane the ass out of that trumpet, they'll take it.  (so will the 14)

You poor buggers up north have a whole different set of issues, ask an Aussie if they've ever had a problem with condensation in the tank, Bet nope,   BTW, Tassie doesn't count as Aussie, ask a Queenslander.

My last three refuels were:
299km @ 15.42km/l
307km @ 16.59km/l
318km @ 16.70km/l

Best is 17.85km/l.
Title: Re: fuel consumption
Post by: gsxbarmy on Saturday, 11 March 2017, 01:25 AM
Consumption is always going to vary depending on how you use it, where you use and how long you use it for.

Cruising I could get about 44mpg out of mine, nice sunny day, no wind. 2 up into the wind that dropped to about 41mpg. If I just used around town, then about 35mpg. If I rode it like I stole it, I didn't measure mpg.

Just polished with Megs (paintwork shiny and slippery) added a further 0.0000458268 mpg to it (roughly)  :rofl2:

Especially with ethanol in the fuel, it loves water.
Title: Re: fuel consumption
Post by: essexboydave on Saturday, 11 March 2017, 10:20 PM
Mines just standard other than a bit of a noisy pipe and I normally average about 10 miles to the litre over a tankful of petrol. Since my bike only gets used occasionally though I have found that filling up with either BP, Esso, Texaco or Total super unleaded and I don't have any problems with fuel going off or water in the tank-this is due to those brands allegedly not having any added ethanol. The 14 is not too bad but the Guzzi is a nightmare if I try to run that on ordinary unleaded it's ok at first but leave it parked for a few weeks and it will not run clean, when I first got it I had to replace all the fuel lines too as they were leaking and apparently this is caused by the ethanol. My old Volvo 760 would frequently play up if I ran it on any other fuel and apparently the plastic fuel tank as fitted to my Jeep will go soft and start leaking if I regularly use cheapo petrol in that! I have also heard from some of the classic bikers I know that old British bikes suffer all sorts of running issues plus leaky fuel pipes, gummed up carbs and rotting petrol tanks, and anything with a fibreglass tank or the Ducati plastic tanks have leak problems or tanks that go soft due to the ethanol!
Title: Re: fuel consumption
Post by: Mick_J on Sunday, 12 March 2017, 08:57 AM
All petrol sold in the UK has at least 5% ethanol in it with the exception of esso super unleaded, which is expected to change later this year.  Most are going to 10%.
As for plastic fuel tanks made by acerbic, the ethanol has water in solution and this is able to penetrate the plastic causing it to expand and growing the tank, this can lead to the tank leaking or touching where it should not.  I have two bikes with plastic tanks and only esso super in them, unfortunately I only discovered this after the tanks were affected, at least they don't leak.

I don't know if it's happening in the old dart but in Oz there seems to be a large amount of vehicles catching fire since the introduction of ethanol.

Post by: grog on Sunday, 12 March 2017, 07:05 PM
bastards, ethanol making its way in here also. water mixes with it. very sad all the old bikes feeling its results. im in car repair industry, stories all starting to come thru. just last week, mazda 3 , designed to run on it, clogged up cat converter, 2800 bucks plus head off to clean it out. another 2 grand. less than 80 th ks on speedo. very bad fuel.
Title: Re: fuel consumption
Post by: Mick_J on Sunday, 12 March 2017, 07:50 PM
I have noticed that Yamaha now fit E10 stickers to their fuel tanks letting everyone know they are designed to run on 10% ethanol fuel.

Had been looking for fuel consumption figures on here. I knew I'd seen the pump flash, then pump and bar flashing fuel remaining figures on here somewhere.

So on Sunday did 330kms two up, got home and the last bar still hadn't started flashing.
I did fill it up from a can and took ages to really fill it up.

I see Seth says he can get an extra 5 litres in if filled up carefully. Well I reckon I had got more that 22 litres on board when we started out.
Title: Re: fuel consumption
Post by: grog on Monday, 08 May 2017, 09:07 PM
Usually 310 on a run loaded, starts flashing. Have had just over 400, was very dry. Filling is the key, slow n easy on centrestand. Very rarely that fussy. 18 k/litre is normal for mine, has never varied. 91,95 or 98 make no difference.
Title: Re: fuel consumption
Post by: Tony Nitrous on Monday, 08 May 2017, 09:47 PM
My tank has a few dents in it and one side pushed in a bit.
(Holds a fraction less)

I don't have stock clocks or stock fuel gauge.

My bike has a Yoshimura Cyclone full system and a dyno mapped PC111.

I know from previous trips, my Sat-Nav and google maps, that when I head North
the town of Childers is 307K's (191 miles) from my house.

I always make it on a full tank with the GSX.



My little game is to try and time the traffic lights in Gympie on the way.
On a good day I can do my driveway to Childers without stopping / putting my feet down.

Standard engine - just the obligatory cans.

Most ever achieved 217 miles. Just been through a nearby town - out of fuel. So, onwards with mate following closely. This was nerve wracking. Out on the missile of nowhere.

I normally do more when the missus is pillion - as I go steadier. For obvious reasons. Now only run on BP ultimate. 47-49mpg. When missus comes along (rare) 51-52mpg.
