Lifted up fuel tank for first time ever....was very mistaken.
That big huge tank....covers the air filter.....the fuel buggers off down some aluminium space bag to an unknown place of magic.....someone with knowledge...explain.

Whatty what? The fuel tank carries some of it's load right in front of your crotch area.

It's quite a normal tank afaik.

Well, I always thought that the fuel tank you see on a bike...stores all the fuel, giving it to the engine when you are on the throttle....But underneath, is just the air filter, with a bag that collects the fuel and pipes take it down to the middle of the bike! Weird...well its not weird, probably normal on ALL bikes, but I have never noticed.

Fuel bag?

If you've got a bag collecting fuel then there's something extremely wrong going on there.

Take some pics of this bag and post them here when you have to lift the tank again.

rofl :D

all the fuel is stored in the tank......


tell you what take the tank off, pull off all the connectors (no fuel does not just poor out) and give the tank a shake, i think you might just find theres fluid called fuel in there :lol:

I will take pics, but not for a while, can't be bothered to undo two screws to just show someone.

And no, it is not just in the tank, thats my point. You think it is, but its the air filter underneath in a black box.

The fuel goes in, and is carried down the bike. The tank, is just a lid basically. Believe me, I did it yesterday and I'm not stupid.

Look closer at things before telling people who know more than you that they are wrong... just IMO.

If you look closer you will see that alloy "bag" thing is just a heat shield held onto the bottom of the tank by some little bent clips.

The tank is steel and holds all the fuel.
Inside tank there is a fuel pump which supplies fuel under pressure via a pipe to some throttle bodies.
The airbox does not hold any fuel, it is just a housing to filter and direct air to the throttle bodies.
In the throttle bodies the injectors spray fuel into the air stream to atomise it, it is then burnt in the engine.

Go on howstuffworks then take another look, or go buy a manual.

c'mon guys I think your all been a bit mean here. we'd all look pretty stupid if it did turn out he had a tesco bag instead of a petrol tank.

Boom boom box take some pics, and if you can pop them into paint or photo shop so that you can highlight the areas which seem to be causing your concern. Im sure that someone on here will be able to give you a straight and simple answer, which should clear everything up.

Even though I kinda knew what he was getting at, I did hope to see some bodge-repair or redneck fuel tank hehe.

lammypie
03-12-10, 03:04 AM
Im going to take pity on him.. i believe he was trying to say that he expected the fuel tank to be more box like in shape (instead of curving around the airbox) and that his suprise is that the fuel tank appears from the outside to be much larger than it is. its that shape to stop the fuel sloshing around so much that it unbalances the bike. besides if the whole space for the airbox was fuel tank i think it would have about a 1000 miles between fills giving the fuel time to go off (kinda clutching at straws)

think im gunna go try youtube some automotive hillbilly bodge jobs. fingers crossed for tesco bag fuel tank

A pointy SV tank holds about 17 litres. Think of how big a 2 litre coke bottle is. So a tank has to be more than 8 times the size of one of those. Plus it needs to curve around the air box. I can never understand how all that fuel fits in there either. It's definitely some kind of magic :D

Now this thread has got me worried.


My bike has not got a 'tank bag' I have seen atop many a bike, now I'm assuming this is for the reserve fuel supply.

Should one have been supplied when I purchased the bike?, just need some clarification before I ring who I bought it from to complain.

You can have 21 or 32 litres fuel reserve if you expand it with the zip. And it's got pockets in the side too, one for oil and one for coolant.

I'm not sure whether to be very sad that people can say such things, or very glad that they will not inhabit this planet for very long...

On a comic twist side, WWII British planes were far superior in terms of amount of bullets they could survive to their German counterparts specifically because they had an internal fuel bag (internal to the tank, that is). This separated the air from the fuel inside and would thus prevent any fuel vapors from forming. This would, in term, prevent the fuel to ignite when the tank would be hit by bullets. The German planes were not endowed with such a design and thus would allow fuel to ignite very easily when bullets struck. This caused an over-proportionate amount of casualties among German Luftwaffe and would eventually help the brits in gaining air superiority.

I would thus consider a "fuel bag" a thing of interest..

ill be sympathetic, when I got my bike i knew very little about it, but knowledge is just gathered over time. When I lifted my tank for the first time I expected the tank to be the same size as it looked from the outside rather than the little bit at the back.

At first glance I suppose the heat shield could look like some sort of bag.... but the actual tank is in behind there I assure you...

I was in the same boat the first time I lifted my tank to run the wiring for my heated grips, too.

"What the.... where does the fuel go?" Not knowing much about bike internals, I was expecting a more or less flat bottom to the tank - certainly not a dirty great airbox.

Everyone has to start somewhere, innit. :cool:

04-12-10, 04:44 PM
I have to admit, when I collected my curvy (1st bigger bike) from a private seller I took tools and restriction washers with me to fit. I lifted the tank, looked at the hole in the top of the air filter and had to think about it for a few seconds, laughed at myself, fit the washers and pootled home.

The engineering made sense (to stop sloshing), but I do still wonder why they don't hold a bit more, vertical fins creating a cellular system inside a tank would would allow for a much larger capacity.

yorkie_chris
04-12-10, 04:45 PM
There a quite a few bikes with big, flat bottomed, empty tanks. The slosh doesn't seem to do much.

Space under tank is more for packaging reasons, IMO, than to avoid slosh.

barwel1992
04-12-10, 10:06 PM
if they wanted to stop sloshing they could just use fuel foam like they use in race car bag tanks..... cheep and works well

Only material point is you looked and did not see what is really happening.

Pretty sure you wrote "the fuel tank is just a lid".

You cannot ask a question about throttle bodies being a place of magic in your OP and then tell me that I am ridiculous for explaining to you how the fuel system actually works rather than calling you an idiot.
Well, you could, but you'd come across as a bit of a wazzock.

This is exactly what I mean. Thank you, for once, someone with sense. And you Owenski ;) I saw your picture in the end, thing is, you are missing the aluminium bag I was going on about.

That "aluminium bag" is heat shield which is clipped to underside of fuel tank... so you can't see it in his pic

i never noticed you write anything reffering to an alloy, so its this;http://bolty.net/wp-content/uploads/2010/03/disconnect_before_removing_sv650_gas_tank-400x300.jpg

As has been pointed out this is the heat sheild.

Generally speaking if something makes you say "WTF this cant be right" its prob that you've got it wrong and may be best if you look into a bit more before you post on here.
As others have said, you're not the first to think its a little odd, but you were the first to post it on here before figuring it out.

You'll get a lot of help from most people on here, but you've got to show you're willing to help yourself first. You took a crack at the hot grips which is mroe than some people are willing to do so you're on the right track, just try not to alienate people from here along the way.

I had a Laverda 750S.When I first rode it I went to fill up and noticed there was no fuel cap on the tank.Took me a while to discover the "tank" wasnt a tank at all,and the fuel cap was under the pillion seat.The "tank" was actually under the riders seat.

My first bike was a Honda MT50 when I was 13, rode it, fell off, fuel pipe came off from the carb and fuel was p1ssing out everywhere.

Me and a friend decided it should go inbetween a random one of the air cooling fins to make it work :D, then pushed it home after all the fuel went into the floor.

Give us some credit, it was dark, we were 13-14...
