getting more fuel in the tank? - sinto607276 - 30-03-15
Hi, just wondering if someone can point me in the right direction....
I read somewhere that you can drill a hole in the neck tube of the petrol tank thus, allowing you to put more fuel in the tank, does anyone have any info on this or can point me where to go to get it?
Thanks in advance,
Colin

What source? Curious to see who advocates holes in tanks! :eek Anyway, isn't that what breathers are for?
On my old Fazer, I used to roll the bike gently from side to side to "slosh" the fuel when filling. Did an OK job at getting the air out, I could always overfill the tank. That said, I filled while sitting on the bike - my logic being that's how the bike sits most of the time on the road.

But I'm sure I read it somewhere on the old yuku site, I've tried searching but not getting anywhere fast :-(

Is it in the tank? Yes.
Are you advocating drilling a hole? Yes.
Therefore a hole in your tank. :lol :lol :lol
I understood ya first time. However, I wouldn't want to have a drill near petrol fumes - nor swarf going into my tank! :eek :eek

Paul, I can't give you pics as I've not done it, I'm trying to find out about as well as was just something I got in my head, mind you, it's fairly empty most of the time ;-)
Re: getting more fuel in the tank? - midden - 30-03-15
Think sinto607276 is suggesting a hole drilled at top of filler tube (higher the better) freeing the possible air trap and thus allowing more fuel.

1. I imagine you'd then have to block the overflow pipes
2. What's the gain, a few extra miles before having to remove your helmet. Whoo :rolleyes
better to carry a jerry can

Thats what I was thinking, it would just piss out unless you rode bolt upright for x amount of miles.

Re: breather mod
You CANT remove the filler neck, however as you rightly worked out it's only the length that's different.
If you look on the right hand side of the neck about 25mm down, you will see a very small bleed hole. All you need do is enlarge this hole, to about 8mm, DONT what ever you do use an electric drill or the hot swarf could well ignite the fuel :eek :eek :\ .
Get hold of a large cocktail umbrella lengthen the stick, pop it in the filler neck, open it and secure it so as to catch the swarf.
Use a HAND drill and go up in drill sizes until you can get it to at least 7mm, drill remove the umbrella, dont worry if any drop in they will just sink to the bottom and do nothing.
Job done
All you do now is fill the tank to this bleed hole, the bigger the hole the faster the fill.

There you go, got it done, originally from 2005 so quite a while back :-(

Whole thread is under 'Cutting the Fuel Filler Neck down' in the mods, mods and more mods in the old yuku site if you want to read the whole tread on it.

Cheers Paul, I can't do that as I use my phone and don't see the page link :-(

The bigger the hole, the greater the airflow, the less time you sit at the pump waiting for the fuel level in the neck to go down.

ahh that makes sense so it doesnt allow more fuel so to speak it allows you to fill it faster...
so could just wait for it to settle

Precisely. Which is what I was on about with my slow "sloshing". Forces the air through a little faster.

WARNING WARNING WARNING
Well mind and vent your tank really well or have a fire extinguisher real handy as it's the petrol vapours that burns and not the actual liquid, vapours will still be present for ages after emptying your tank of fuel.
