250 miles from a tank.

[Lumpy]

well impressed as the last tankful on my 98 got to 250 miles before I chickened out and refilled it, 64mpg when filled up, with care you can get just over an extra litre in the tank which helps so still had 1/4 litre in there.

[darrsi]

Have you got an original 18 litre tank, or have you upgraded it?

Bugger i only get between 130 and 170 to tank , 1998 600 Gen 1

I think 10 miles per litre is probably a rough guideline, obviously depending on how you ride and in what circumstances.

it's the original tank, albeit a horrible paint job


keep thinking about the later tank.

the first bikes had a very long filler neck. You can open up the internal vent hole to 10mm, and add an extra 2 liters to your tank. Did it on my 98. I used to get 200 miles out of it then.

Crikey, that ain't bad going at all. 
I've never considered letting my tank get low, the thought of running out doesn't appeal to me at all.

I am going to drill a 2mm vent hole, that's all it needs, to aid filling, there is bound to be a good reason Yamaha designed it with an air gap though.


The front sprocket is 1 tooth up and most of it is commuting 1 and 2 up but shortshifitng. Saying that when giving it shitty death it still gives 55mpg plus

[darrsi]

Just wondering, but what about swarf or filings in the tank after drilling?

[richfzs]

Hehe, or sparks while drilling, be careful out there!

i assume those would find there way  to the fuel filter, and that you would rinse the tank out thoroughly with soem fuel before re-onnecting it?

I used a cocktail umbrella, closed it up, placed it through the filler neck and opened it up, taping it in place whilst I drilled an 8mm hole where the already puny 3mm hole is. Once the hole was done,  closed the umbrella, and removed it from the tank with swarf in it. The tank takes another 2 litres now.
Yamaha realised how long the neck is, and reduced its length for the 2k model. (hence its 2 litre larger tank)
You need not worry too much about crap in your tank, have you ever emptied the fuel tank on a 10 year+ bike, there's normally all sorts of crap in there cleverly filtered out by gravity and the mesh filter.

I wouldn't bother with 2mm, there's already a 3mm hole there. I tried 5mm first, and it still took forever to get the last 2 litres in. Opened it up to 8mm, and it was better.
As for the air gap, pretty much all tanks have an air gap for fuel gas expansion should you experience a sunny day on the UK to leave your bike out and exposed with a full tank of fuel.

I wouldn't over worry about the filings, there is a magnetic bung on the bottom of my 99. U can see it when u look straight into the tank.... ( see it slightly better when it's empty  ) I hadn't a clue what it was until I seem crap stuck to it and when I put an extendable magnetic  screwdriver in it got sucked to it lol.

I'm sure even a very small air gap is fine, just make sure your vent pipe isn't caught or kinked under the tank, which has happened and the tank gets sucked in....

Not sure how your magnetic bung is gonna help my bike?

I get better than that from my blackbird so would be appalled if I only got that out of the 6.

As i said, depends on your circumstances.
If you ride in traffic everyday (me) on shorter runs, then mileage will definitely be less than if you were steadily cruising down a motorway at 60mph over a long distance.
Anyway, i think 200 miles on a 20 litre tank is a very good, albeit rough guide!

[Chris]

I usually fill up when I get to about 200miles and i've usually used just under 18 litres. Having said that I don't do much town riding mostly open roads.
 
I've got an 02 bike with the biggest of the tanks the 600 had so should easily get 240 to 250 out of a tank.

What? I only get about 140-150 from full until red light comes on.....

[darrsi]

I'm pretty damn accurate 'at least' with the 10 miles per litre, something ain't right.......check your top box for refugees, they can bog you down a bit!

[darrsi]

Mind you, reserve is apparently 30 miles so that sounds about right!

[dcurzon]

'99 and I get 200 to the red light coming on. London commuting

[darrsi]

Fuel's a weird one, 'cos i'm always in traffic, i dread to think what i get per tank, that's why i don't really wanna know?

[hightower]

Last time I checked it was working out about 49-50 per gallon. I do various riding, maybe about 50% 30-40 mph with gentle acceleration, but as soon as the national speed limit comes (the other 50%) I open her up good and proper. Not much sitting in traffic for me.

[mtread]

A quarter of a litre, even at 64mpg is just 3 and a half miles. Gulp, nearly a push job
