Accuracy of miles to go readout

As to drilling the filler neck- if you do this are you a bit simple? The reason the neck is recessed is to prevent it leaking past the cap when the bike is upside down, which happens on a off-road bike.
I'm not sure I understand this. I've had a look at the filler neck/tube and can't see what safety element the tube provides. Could you explain what the danger is?

I thought that the whole point of the neck is to prevent the tank being fully filled. This forces the rider to allow some air at the top of the tank to allow for thermal expansion of the petrol.

If you drill the neck and completely fill, you've got to make sure that you don't just ride 100yrd down the road and leave it in 40deg of heat - otherwise you'll be ok.

Cannot see any other 'safety' aspect that this. It certainly won't stop fuel leaking out if upside down.

This is a crash safety requirement for YOUR and OTHER people's safety.When you drill the neck to allow an extra teaspoon of gas to go in, and you fall off with your leg stuck under it, petrol could drip onto you and ignite, think of the Goose in Mad Max! Hey, but what do I know, go torch yerselvvves....
Whilst lying in the middle of the road this morning, courtesy of a black cab (:eek: :mad: ), I can confirm that fuel does not leak past the cap, but goes down the overflow.
 
Sorry, but Mouse's comment made me roar with laughter :D:D

Sorry to hear about your off, much damage?...but hey at least you don't smell of petrol ;)
 
Filled up in Louth yesterday.... (14 miles left on reading!!... 16 miles to get to Grimsby!!).. Got 19.5 Ltrs in tank... checked Ode from last fill... 210miles.. mostly 2up!!.. some tear-arsing about, some cruising 80ish.. some C road pottering!

Again last litre or so.. is a tad slow to get in...

P.S.. Have run it past zero b4 today.. and still made it to the petrol station ;)

Oh.! and the rev limiter works at spot on 8500!!!... was giving a Fazer1000 a run for his money :D

I was told by a motorbike journo mate of mine, that, when he had one on long term for an article, he ran his down and found out that when it says 0 miles to go, you've just started reserve! It's a pet hate of his.

Mine's a late model(sept) and so, I ran it down to 0, then blithely rode for another 20 miles before filling up, by which time it was on vapours! Perhaps the early gauges calibrated 'empty' differently, but I always just use the trip, and when I've done 200 miles, fill up( mostly town work BTW), and its about 18-19 litres

As to drilling the filler neck, are you mental? If you fell off, and ended up under the bike (off road bike-duhhhh) petrol could leak past the filler cap and onto you/hot exhaust, hence the inset neck, it's a big safety feature. Remember what happened to Goose in Mad Max.......

......and not to mention that fuel, like most liquids, expand and contract under different temperatures......so fill to the neck in warm air, park in the blasting sun and guess what comes out onto a possible hot exhaust............ !!!! drilling filler neck.....worth it...hummm, you decide!!!:P
 
1. Obviously you only go to the trouble of brimming the tank if you're concerned about fuel range. You have to get the machine on the centre stand to get maximum capacity and only an idiot would then park the bike in the hot sun.

2. Nevertheless, it would have little effect as the volumetric thermal expansion coefficient of petrol very very very small (950 x 10 -6 per degree C)

3. Having started riding, fuel consumption on the R1200GS is about 100cc per mile, so five miles down the road you will have a half-litre air gap.

Mouse Funnily enough, when I was lying on the floor I was looking at the bike thinking "That fella who said petrol would leak all over the place was talking out of his arse"....funny how the mind works:tosser

Clive Sorry, didn't have a camera with me at the time. But picture the scene.....07:00 dark winters morning. Me in the middle of a one way street on my back, pride and joy next to me. I didn't get up, I just sat there in the middle of the road for about 10sec thinking "I've only had this for two weeks and I've trashed it already!!" Then got up and was surprised at virtually zero damage:D :D If it'd been my old CBR it'd be a bunch of cracked plastic.

Bert The fuel overflow gets routed over the top of the exhaust anyhow. I didn't burst into flames when fuel leaked out. I don't intend to fill it up then leave it in the sun. I'm the type of guy who thinks "This product may contain nuts" is not required on a packet of peanuts.

Zmeagol Common sense as usual:)

Glad you're ok!!! :beerjug:

How did it happen and what was damaged?
I was filtering down a one way street and went to go for a gap left in front of a taxi. As I moved across, the taxi went into my rear quarter and punted me off. Very little damage to the bike, only the cylinder protector was scuffed, which you can't complain about really, as its there to protect the cylinder!! Minor scuffs were added to the hand guards (regularly clatter them agains van wing mirrors anyway) and a slight scuff to the can.

All in all, everything is ok. First accident I've had in five years, last two bikes never even got dropped.
 
Yesterday I filled up with 4 miles to go on the gauge. By slow filling I managed to get 20.68 Ltrs in the tank. The mileage on the trip, zero'd at last fill up, was 252 miles. That means I'm getting in excess of 55mpg at a very rough estimate (no calculater to hand!) That's pretty good I reckon.

Whats up with you people. You buy your petrol in Ltrs but drive at MPH.:confused:
 
Eyeguy.......get yourself a cup of petrol, heat up your engine as hot as you like and drop the petrol onto it.......

It won't ignite.......it needs a spark.

Fair enough, if your HT leads are damaged, you may get one, but there's no danger in having petrol dropping onto hot exhausts or engines.......

(As Rob Farmer will confirm ;)

Scares the living crap out of you mind.....

:D :D
 
The autoignition temperature (temp that it will spontaneously combust) of petrol is in excess of 400degC. So you could maybe get a fire going if you let the bike idle for a few minutes than throw onto the downpipes, close to the exhaust port. I don't recommend that you try this though, unless you're wanting to claim off your insurance:D

Can't say I'm particularly worried about all this re. drilling filler neck.

No, me either. It takes a little longer, seconds really, than the Africa Twin or my old 100GS to fill to the top but, I still manage to fill it to the rim.

Price here for 96 is $1.19Litre kiwi or .85cents US
Well its probably about .50cents US a litre here, its just the extra $1.50 US that the tax man robs that hurts:mad:
