I'm curious, when and where is the 10% ethanol added to the gas? I've seen a gas station way out in the middle of no where with a sign that says ethanol free gas. Also is ethanol free gas from a no name gas station better than lets say a Shell or Chevron station who advertises their 10% added ethanol gas plus additives as being better for keeping your valves cleaner?

I don't have any scientific evidence to support it, but I use ethanol free gas whenever possible in my bikes, garden equipment and RV (primarily for the benefit of the Onan generator). Everything else gets Shell regular. Ethanol free gas is readily available near most recreational boating areas. www.pure-gas.orgAt least around here, most stations get their raw gas from the same tank farms and just add their own brand specific additives. I'm guessing the ethanol was added during initial refining. All things equal, I go for the busiest station to help insure fresh gas. That seems to be more critical with the ethanol since it attracts water.

My bike will run a full whole number richer (per AFM) on non-E (pure gas) than it will on E10. It also gets slightly better fuel consumption on non-E than it does on E-10.
A carb bike can be optimized for pure gas, or optimized for E-10; it can be compromised to run either, however it can't be optimized to switch tanks without first wrenching it.

At the tank farm. There was some talk recently about trucks dumping the corn in the underground tanks at the retail end, but that's not correct. I have a friend that hauls gas and the E10 is mixed and loaded at the tank farm.

So the trucks have to make special trips with the "non ethanol" fuel?

We have a pure gas station close to me. I've not used it but everyone I know gets there small engine fuel from them and claims much healthier running from lawnmowers,weedwhackers,chainsaws and the like. Personally I just add an ethanol fixing agent and get gas wherever I want.

No, the ethanol is already mixed when he pulls under the feed hose. The same stop, different feed for pure gas.
Your bike will run fine on 10%. There is no pure gas for the entire metropolitan area of San Antonio so just got used to it. I notice no difference other than the moral issue of "Why are we driving our food?".

Nope, the tanker has as many as 8 baffled sections, they can carry 87, 89, 91, diesel, whatever on the same load. The driver can even put lunch and stuff on the passenger seat.

I thought they didn't have passenger seats so that the drivers knew what side to get in.

I wonder if you guys in the State's use a different rating system than us. Our lowest rating is 91 which all stations sell and 'Super' is (depending on brand) either 95 or 98.

Ok answered my own question. Google is your friend. An excerpt from Wiki- In most countries, including Australia, New Zealand and all of those in Europe,[citation needed] the "headline" octane rating shown on the pump is the RON, but in Canada, the United States, Brazil, and some other countries, the headline number is the average of the RON and the MON, called the Anti-Knock Index (AKI, and often written on pumps as (R+M)/2). It may also sometimes be called the Pump Octane Number (PON).

Has anyone tried using 87 Octane (US) rather than the recommended 89? I have run a few tankfuls through and it seemed to run the same. 9:1 compression isn't all that high but I am not familiar with the shape of the combustion chamber on a BA. If I don't get any pinging I am thinking 87 is just fine. Will some more experienced folk jump in here?

I'm thinking the recommended fuel for mine was regular, nothing more was needed for stock configuration. After cams & big bore the shop recommended mid grade as the c/r had gone up a little. They said nothing "wrong" with still running regular but mid grade fuel would be a better choice.

Yep...however, with a remapped igniter with more advance or a big bore kit, or hot cams &/or in really hot weather, then I suggest 89, or 87 with a little Lucas Octane Boost.
