Title: Running on empty.
Post by: Kiwifruit on Tuesday, 12 September 2017, 08:52 AM
Pleased I stopped for fuel and didn't try to go any further. Thought I'd fill her up.
Ooops nearly pushing  :facepalm:

I have a fuel pressure gauge in my bike for certain reason. I have noticed that the fuel pressure starts to wobble when 19 liters is used,
even she runs ok.
So, it may not be safe for fuel pump to use those last three liters?.

That's a big drink for the girl Col!    Cheaper gas up there than we get down here, we're over $2.00 a litre for 91 & about $2.15 for 95.

Geez KF, you were cutting that bloody close  :facepalm:

As T 24 has already mentioned, probably not a good idea to run it that low if you can help it.
You have been a bad boy, so go sit in the corner on the naughty chair (but take a beer with you)   ;)

Wish we could get fuel that cheap  :shocked:

What's it cost where you are Mick?     Aussie get it much cheaper than NZ too.

Don't know about the fuel pump. But riding pleasure can certainly suffer. My current 14 has never had less than 4 liters in it. My first (brand spanking new) had problems with less than 3 liters when ripping the throttle fully open while going up steep hill.

I have not tried to use full throttle, while fuel pressure is wobbling. I dont want to burn holes to my pistons.

Wouldn't either. That's why she stays plenty fueled. Just normal driving puts enough Gs into the game to cause pressure fluctuation by low fuel level (as you noticed through pressure gauge).

Your fuel works out at about £0.93/ltr, we pay about £1.18/ltr, that's a over a fiver per tank full.

Its rare that I run it that low. Only had 276k's up, dont usually look for gas till 300k's shows. I guess it was a bit shy when i filled it last.
Interesting point about the fuel pressure. Will keep that in mind. I'm also starting to wonder if she's running a bit rich. The pipe looks quite black.  No complaints about the bikes performance.
Still get silly grin face....every time i ride it.

Small item but I wish they would standardize the colour coding of the pump/nozzles. Not a problem if you never leave your country but when biking around the world one has to double check all the time.

Whats the capacity of the tank in these things?....I regularly run it till the last fuel indicator bar is on & flashing resulting in 20+Ltrs going in....figured it was at least a 25L capacity....
Title: Re: Running on empty.
Post by: KiwiCol on Wednesday, 13 September 2017, 10:05 AM
22L, pretty sure.
Title: Re: Running on empty.
Post by: Kiwifruit on Wednesday, 13 September 2017, 11:23 AM
Yep, handbook says 22L.
Title: Re: Running on empty.
Post by: HLAH on Wednesday, 13 September 2017, 06:04 PM
Right-o, noted...id say the last 5+ fills ive put in over 20L....must have been real close to stopping...Ill be a little more conscientious of my fuel management from here on in...
Title: Re: Running on empty.
Post by: Kiwifruit on Wednesday, 13 September 2017, 06:32 PM
 300k from full is when i start looking for gas. But i must have been a bit shy of full last time and thats why i nearly got caught out.
Title: Re: Running on empty.
Post by: grog on Wednesday, 13 September 2017, 06:58 PM
yeah mate, you mustnt have filled. my first bar always starts flashing around 310-320 ks. 6 l left. most ive done is 410, nearly 22l to fill. scary.
Title: Re: Running on empty.
Post by: Sweaty on Wednesday, 13 September 2017, 07:58 PM
Ok, when you guys fill, what is your cut off point.
I stop when the fuel starts hitting the internal filler tube (if you know what I mean) but I'm sure I can keep going.
Title: Re: Running on empty.
Post by: Andre on Wednesday, 13 September 2017, 08:32 PM
I fill up to the internal filler tube. That gives me a good mark to measure fuel consumption. Also, I won't go higher as the fuel expands when getting warmer and I don't want to lose even a drop of the precious stuff.

Yours is much more economical than mine Grog, 310 - 320 & I've got both flashing! I'm out. No way I could get 400K out of a tank.

I fill mine right to the top each time, basically up to the cap as I'm usually going somewhere & it won't be sitting around with a tank filled to that extent.

Fill mine to the cap then ride,  l dont fill it and park it.
Years ago I was at Amaroo for the Castrol 6 hour. It was all the go to try and freeze fuel to get more in. Well it was cold and pissed down all day. Many bikes were getting round with a hard frost on their tanks. Very unpleasant !!
