My ride home (with special bike-push novelty section)

My reserve light nearly always comes up at 100 miles (taking roughly 15.5 litres in). Regardless if it's a commute, weekend blasting or on track (!). I've just learned to accept that :) and trash the girl as she (clearly) demands. Isn't this what she's trying to say between the lines, after all?

I think she's trying to say give me a rest if its running out that fast.

I find the fuel consumption relates to how it the bike is being ridden.
A while back I guided my daughter back form picking up her new car and did 160+ miles on that tank and used about 20% of the bike's capability.
Normaly I get 100 - 120 miles from about 15 liters and use about 70 to 80% of the bike's potential.

Hmmm.. I stick by my theory that low mpg bikes are running very rich. My bike is not nursed and I defy anyone to ride back and forwards over the unrestricted sections of the TT course without giving it a work out each time. When I fitted the race cans on my original Falco the engineer who serviced it the next time round spent a fair amount of time and effort getting the fuelling right. This was with the RSC cans and the SLCarbon chip supplied with them. The bike was running way rich without further adjustment. My current Falco, running the chip supplied via Bef is not running rich. I would have to wring the neck out of the bike constantly to reduce the fuel consumption to the point where it did only 100 miles to reserve. As the bike does not perform at its best at the top of the rev range, this would be pointless. You often hear about these quite large discrepancies with fuel consumption with the Falco and I don't believe it is all down to the method of riding. No doubt an expert will be along shortly to give an alternative view.

Yep - I've held the view for some time that it's running rich - and I also think it doesn't do so well on short commutes.

When I've got the cans changed I'll go for a PCIII custom map to try to get the fuelling sorted.

Mind you - the 113miles to bone dry is the worst I've had. On a long run I once exceeded the 140mile mark without the warning light ever flashing at me.

And I am still puzzled as to why D R only got 17 or so litres into a dry tank

How do you get more in?
When I fill it I always get the fuel some way above that interior hole that you stick the nozzle in.
If you can get it significantly more full, I'd love to learn how to do it.

What I'm getting at is that I usually get 15 to 17 litres in and I don't (as far as I know) run it to dry. I have always assumed a tank capacity of 20 litres with 5 in reserve (light coming on).

Am I wrong about this?

Because surely if I am correct then...

either your tank wasn't empty or........

It has a reduced capacity or......

You aren't filling it up fully.

Of course I hope never to be put to the test of seeing how much I can get into a dry tank

One of the ways I increase range is to make sure I get as much fuel in the tank as possible - or that WAS my concern. I used to sit on the bike and fill the tank whilst gently rocking to ensure that no air was trapped. This way I could get the tank filled right up to the top. About two weeks ago, whilst doing this, I got a back up of fuel which erupted out of the tank into my face and eyes. The petrol also etched into the screen. Poxy garage would not let me use their toilets to wash petrol out of my eyes as they were "not allowed to let anybody in past the office". I had to use a tap at the side of the garage. Anyway, it was not a pleasant experience.

I now dismont the bike and just get in as much as I can. The Falco tank has always been difficult to fill to the max. This might be another reason why mpg differs. If you start with 2 litres less, it makes an appreciable difference.

Hammy could tell you all about spilling petrol while doing that.

Summat about continental roast nuts as I recall.

Umm, doesn't make the slightest bit of difference to MPG - only makes a difference to tank range.

Yes, that is what I meant, of course.
