Learning this would put me off ever wanting to own a 4-carb bike like say a CB1000 (even if I was into 4 cylinder bikes which I am not anyway), Imagine the hassle of regularly cleaning 4 carbs, 4 fuel lines etc.
All this sways me even more in the direction of Singles or Twins.
Also I wonder would it be the case that a large single like a Dominator would have a large carb with large jets which would be slower to gum up?

Just been down to the lock up and run the Undercover and the Bandit....
Funnily enough, the deluxe has now used all the fuel that was in the tank......so basically she is now totally dry. I had an inspection inside the tank and to be totally honest, she still looks pristine in there - not a hint of rust - also no hint of corrosion of any kind on the reverse of the fuel cap - still perfect yellow zinc showing...
Is this all a load of hype?

Just to clarify something. Is the issue going to be with the fuel when it gets older in the tank or is the issue with the actual fuel itself - the way I am reading it and hence the panic is that the actual fuel will cause us problems without even the issue of being left to 'go off'...
Is that right or not?
I can live with draining my fuel out every winter but my actual concern is the fuel doing damage when it's in the system but still being used.

If its in contact it will do the damage not instant but overtime on metals, on plastic and rubber not long at all I stood a plastic paintbrush in some to clean it but was called away and forgot about it .It was left overnight when I went back the next morning there was a snotty melted stub and a few bristles floating on the surface

Please tell me you are only joking about the paintbrush, if this stuff can dissolve bristles then we are all F**ked !

They were nylon bristles so yes most of them dissolved it was only a cheap brush . On the plus side there is allready fuel lines on the market that are Ethanol proof and jets will be available before it becomes a real problem to us

Gents, sorry to drag up an old topic but I've found a solution for the problem. Been out for a few beers with a mate tonight who's still involved in racing. Ethanol's bad news for these guys too as it's not good for power, so it needs removing from the pump gas. Quite a straightforward process when you think about it.
What we do is pour say 5 gallons of BP's finest into a big drum, and then add a couple of litres of plain tap water and agitate (I reckon a fish tank aerator would be ideal for this) for about 15 mins. As you know, ethanol is soluble in water but petrol isn't. The water will draw the ethanol from the fuel and settle at the bottom of the drum as petroleum distillates float on water, allowing you to syphon/pour neat petrol from the top.
Surprisingly, from all the fuels that have been tested, Morrisons contains less ethanol than all the other brands.
Just thought I'd share..

I'd recommend that before you try this out, check up in it a bit more in case the lads had a few drinks on them when they told you this, maybe they are ethanol drinkers but didn't tell you !

Sorry pal! My first reply was maybe a bit harsh, so I have hopefully deleted it. May I politely suggest that you try my theory with a measuring jug, some petrol and a little water, as I have this evening. Then you may reply with your findings.

Very interesting research, Listey. Thanks for sharing.

Only winding you up Listey, your theory is excellent and makes perfect sense. Although I haven't got the room to do this process, someone smart will and then they will get a licence to sell it or what ever. It may be a bit dearer but I only clock up very small millage on my SDs, so happy days ahead, classics bikes will live on !

There is hope for the longevity of our bikes..... It is great to have options.

I'm in the middle of rebuilding a 1994 CB500. It's not been taxed since 2009, but belonged to a guy even older who used it on high days & holidays so the mileage is low and the bodywork was in fair condition. I've done one before with no problems, but this one's being a pain. This is what I found under the sound paintwork on the tank:- That was last week - the number of pinholes has doubled since then! That's the left side of the tank, same as the side stand. There's a couple of holes on the other side, but nowhere near as high. IIRC water is denser than petrol & would sink underneath it, so I reckon this is due to the ethanol absorbing water. I've treated all Gill & my bikes tanks for the winter, but now I'm beginning to think draining them is the only way to go.
