after readin all these mpg you guys are'a gettin, I better shut the throttle orf'a bit,or take the motor...
tank range
- Thread starter smartbear
- Start date
Just looked in hand book, when down to 0 miles, you then go on to reserve fuel ie 4l left.

Always get 200+ to a tank on my 56 GS. Managed to get from Edinburgh to Hull, 243 miles, one a tank, panniers loaded and sticking to decent round about the limit touring speeds on A + B roads.
Be careful when filling
In hot weather (if/when you have any in the uk) you can get quite a build up in tank pressure if you fill right to the brim; Leave some margin for fuel expansion - otherwise it can spray out of the breather - onto your rear tyre!

A question of climate.
Thank you for your kind advice. I know what your temperatures are like in Manchester; here it can often be around 40°C at road level in the long hot summers! (Just to rub it in!).

Thank you for your kind advice,
but i have ridden farther than the outskirts of Manchester 
I confess
I am sure that no GS owner would confine himself to Manchester 'et environs' and I also know that Manchester is a beautiful city with an excellent university etc;etc; so i apologise if you have been offended!
I was only quoting what is said in my (French) handbook - and possibly in yours too? Here is my translation: "Petrol expands under the influence of heat.If the tank is filled too high petrol can escape and end up on the rear wheel, with the consequent risk of a fall. Fill up only to the bottom of the filling tube." It seems to make sense to me.

I'm not really sure what I am doing wrong. I have an '08 GS, and in my first 2,000 miles, I am averaging just under 40mpg.

And you think running the bike dry once is an accurate way of telling how far you can go?
Pretty much the most accurate way, yes. And why are you implying that it would only be done once? Do it several times on several different rides, and you get some useful information.
Science, you see, it can be your friend.
Whatever.

Silly question really, why wait to fill up, potentially running out of petrol???? Surely, if you reset the trip each time, you will know how many miles you've done, and if you fill up to the top, you will know how much fuel you've put in.
But you will not know how much was still in there, though. After all, you don't know how close to the capacity you have filled when you pull out of the garage, so will be left thinking "could I have fitted two more litres in there if I'd taken a bit more time, or only a few hundred milliltres? Even if you ran the petrol over the top, you still cannot tell if there was an air gap.
No, the only way to actually tell how much yo ucan get from a tank is to actually run the tank dry, and see. Even at my terrible consumption (I am getting less than 40 miles from each gallon of BP Ultimate), there is still about 30 miles left when the countdown clicks down to zero. Knowing that gives you a whole world of extra options when you are far from the density of petrol stations that we are used to in the UK.

??? Whatever what? That post makes no sense. Is it some kind of "in joke"?
Nope. It means whatever you say.

".....No, the only way to actually tell how much yo can get from a tank is to actually run the tank dry,...." I have to refer to the dreaded instruction book again and, translating into English it says " any fuel shortage can provoke back firing and stalling of the motor. This backfiring can damage the catalyser and the motor stalling can cause an accident. Don't run until the petrol tank is empty...." ;

Nothing to be offended by.
I dont like looking into a petrol tank when filling, to see how much petrol there is in it i tend to stand to one side.
First oilhead i bought was r1100 rs in 95 and did the fuel filler mod [some people seem to think its a recent mod to BMW ] did over 100,000 milles on brim and ride, bought r1150 rs same tank mod same brim and ride, bought 1200gs same tank mod same brim and ride, now 08gs no need for tank mod
neck already vented, so easy to brim and ride.Brim and ride means just that, dont brim then stand around around talking.
Hand book is only a guide.

What Dennis said!
Brim it to the max then ride off. Never had a problem doing it yet.

We live and learn
I was only a humble rocket scientist (yes, really) and an Engineer I knew managed to 'implode' a Blue Streak rocket - ignoring the compression and expansion of gases! It cost (the taxpayer) quite a lot of money in those days when five or six zeros after a £1 was a large sum.

<sigh> Blue Streak blew up because your colleague overfilled the tank? 
See the Germans got it right by not over-filling their rocket tanks
If only we still had our own space industry

Just the reverse in fact
No, in fact the rocket 'imploded' - that is to say it collapsed due to the atmospheric pressure; It was undergoing a cold test and the oxygen tank was beng filled with liquid nitrogen. The (empty of fuel) tank beside it of about 16,000 gallons was not kept up to pressure as the gas inside cooled.
No, its is not really relevant to this thread except that I am always wary of tanks and changing teperatures; - and I did sign the official secrets act - but that was all 50 years ago.
