I had some nasty issues with the 88 I just bought's gas tank as some have seen. I got a new tank, but had to use the old hardware. I found out after 1 single short ride.... I needed to do some work.
Then what do you call all the crap you said and are still talking about me?Well folks, what can I say ... I have a negative response to sarcasm, arrogance, condescending and denigrating remarks when it's absolutely not warranted.
Apparently it hasn't because someone is still being allowed to make personal attacks while I get dogpiled on and warned to shut up. Fair and balanced, I'm sure.I think it's run its course here ...hopefully....please no more or I'll have to close this thread.
That understanding is flawed and has little to nothing to do with E10 in an organic hydrocarbon base. Chemical properties vary hugely based on concentration, in some cases at an exponential rather than linear rate. https://en.wikipedia.org/wiki/Rate_equation In fact, some chemical reactions won't take place AT ALL until a certain concentration is reached.From what I understand from my years in chemistry class, all alcohols absorb water. So much so, that there's no such thing as "pure alcohol" , even anhydrous alcohol (which means "no water") still has trace amounts of water in it, and will absorb more from the atmosphere.
Exactly. That's because it's hydrophilic. It actually helps, especially if you have a water issue with your bike sitting outside or something.This in fact is a good thing, as long as you're putting it through a system at a fairly constant rate.
Think about this for a minute. Gas with water in it so it settles to the bottom of your carbs and tank vs gas with EtOH suspending the water in much lower concentration. Denatured alcohol (ethanol) is used all the time in marine systems to treat fuel: Water in the gas [Archive] - Boat Repair ForumLet it sit for any amount of time, and of course the water can react with whatever can react with it.
Which means to me, don't let it sit in your tank or carbs for a long time.
Again, chemistry varies widely based on the concentration of chemicals. E85 and E10 are very different for seals. E10 is just fine and has been for decades, especially since manufacturers changed types of rubber way back when. If you're talking about the cheaper isobutylene/isoprene, that's just as susceptible to drying, shrinking, and cracking from gasoline alone because it contains toluene and other additives. Anyone who has worked on as many old carbs as I have has seen this.Actually ethanol is horrible for seals and aluminum
Yes it is, but in most cases it didn't. It gets there from bad gas and people leaving their bikes in the weather. As I said, ethanol doesn't have appreciable moisture absorption from the atmosphere in this concentration and medium especially in a FUEL TANK. Tanks have a vent to equalize pressure, sure, but only a TINY amount is going to change, and that's only if you have a big open space in a nearly empty tank and, even so, most of that space is going to be filled by fuel vapors because of the vapor pressure of isooctane and toluene, and that won't allow much of anything to come in unless you have huge and regular swings in temp during damp conditions, like leaving your bike outside. Due to the vapor pressure of gas, the absorption rate in a closed tank at low concentrations, water isn't sneaking its way in through the vent. Generally, gas is sneaking OUT.(you are correct that the white stuff is probably aluminum. It got there from the ethanol though.
