I'm tired of this...

The issues caused by running pump E10 through my Amals have reached critical mass. I've dealt well enough with popping them off every 2 months on average to remove trash which I cannot see getting past my inline filters.... As soon as performance and starting goes to hell, and it pops and blubbers I clean them.... Okay, I'm good to that point.... It's just when some speck is missed and makes a beeline in right after putting it on the road that I crack..... This never happened in the old days when I could feed this fine machine properly.
Now for the question I've been pondering.... What does this race fuel octane boost stuff I've seen on offer at Summit and other places really work out like when mixed with the lower octane Ethanol-free pump gas I can purchase about 15 miles away?

As to your current “junk in the carbs”, what is the condition of your gas tank? If fiberglass, it Isn’t going to work. If steel with some tank liner goop, it isn’t going to work. None of the tank lining chemicals has lasted for me as the ethanol eats it all. Bare steel inside so far has been OK, but I don’t leave that E10 in the tank very long.

Race gas works great, but if your on the road and need to refill, then what?

You could remove the ethanol from the fuel, however, you will be throwing away 10% of your fuel and lowering the octane by about 3 or 4 points, and as above, if you need to fill up whilst out, then you are back to square one. How would that compare price wise to avgas or octane boosted low test?

I have no experience with this, https://torcoracefuel.net/products/torco-accelerator, but have read positive reviews.
I have just ordered up some to try in another application, hopefully not to distant future.

Firstly I never travel more than a tank's worth anymore. Secondly there's nothing in the tank except the gas. After the electrolysis and multiple flush/washings the tank is as clean as it can be, also inline filters on each tap to pick up possible escapees.
Lots of humidity here and the inlines also double to trap water which leads to draining and drying out the tank every couple of months also.... My gas here, regardless the vendor, is shockingly trashy.
I'm just trying to figure if the mixable stuff is any good and worth a shot. If it is I can do 10 or so gallons(US) at a time and perhaps alleviate this misery. Besides ethanol is not found in a Commando in Nature.

That info looks interesting MichaelB. Thanks.

I just realized we are forced to drain our sumps after riding due to bypass of the pumps and now we are busy draining our carbs and tanks as well!

The water absorption by the ethanol is our (amal) killer. If you run your tanks out in under 30 days you should be OK long term. The ethanol kills rubber, plastics, polyester Any "resins and most tank liners. The water absorption is what corrodes brass and the white metals zinc/aluminum etc. fresh gas no water no metal corrosion. Any "ethanol fuel treatments" supposedly has an enzyme that interferes with the alcohol "chaining"(which is accelerated by water) and dropping out as the phasing. If there is a few drops of oily stuff it might help prevent rust. There is isopropyl alcohol to absorb water, seabond is the same but has 4X the alcohol due to the humid marine environment. Methynol and lite petroleum as an igniters.
2,2,4-Trimethylpentane 80-100% of torco accelerator
caviat? MMT photolysis rapidly in water.
photolysis = the decomposition or separation of molecules by the action of light.
Yes octane boost not denying that .
found it interesting....

What a goofed up world we live in. Oil is below 40 dollars a barrel and yet we seem to think we need to produce corn to put into our fuel. And we subsidize the whole mess with tax dollars. Oops, did I just swerve into the pol lane?

I agree on bare steel. If the bike is used often, then the E10 hurts nothing. If not and the tank is kept full then it's probably not a problem. I don't care how rusty a tank inside is, I won't coat one - I get rid of the rust, keep the tank full, and try to never use the reserve.

Different point of view here. l lined a tank with POR15 close to twenty years ago. It's had e10 in it everyday since with absolutely no deterioration. l've also used Hirsch and Caswell liners with good results. Never tried Kreem but there a lot of horror stories about it. Needless to say any tank liner will fail if not installed correctly.

One would think that refineries would be able to make gas which is uniform in composition and quality throughout the USA (including blending in E10)
I have only had one bad gas experience in the last 17 years. Water in the gas. Drained the gas out and put new gas in. Voila! I find no crud in my Amal or Mikuni or have injector problems with my Yamaha. Perhaps you live in a high humidity climate and the E10 is just plain sucking the H2O out of the air?
Have you tried dosing your gas with Sta-Bil ? Any gas I store in a bike for over a month gets treated with this. All of my gas powered tools get gas
treated with it. I am not an investor nor do I have any interest in this product except as a consumer. Where I live, you can't buy AV Gas if you don't
have a plane, and the closest location to buy E10 free gas is 200 miles away.

For the time being we look to be lucky in the UK; Taken from the Esso UK web site a few minutes ago :

The majority of unleaded 95 Octane petrol sold in the UK contains up to 5% ethanol as required under the Government’s Renewable Transport Fuels Obligation (RTFO).
There is currently no requirement for renewable fuel (such as ethanol) to be present in super unleaded (97 grade petrol).
Esso super unleaded petrol (Synergy Supreme+ Unleaded 97) is ethanol free (except in Devon, Cornwall, the Teesside area and Scotland). We would therefore advise anyone
who has concerns about the presence of ethanol in petrol to use Synergy Supreme+ – providing they do not fill up in Devon or Cornwall, the Teesside area or Scotland.

Have mentioned before but , will pass along , I buy 5 USA gallons of 116 oct racing gas at local bike shop , I buy high test non-E gas at pump and mix 70% pump gas and 30% racing gas , I add stabilizer to mixture and run it in Norton exclusively , like you never go further than a tank full ..... the race gas is costly here so I use the stabilizer with 100 in name sorry complete name escapes , but with correct dilution it keeps gas for 2 yrs , which is how long the 5 gal can of race gas lasts me ..... hope this helps , non-E gas still relatively easy to find around here .... I’m still using original GF fuel tank with no issues ..... mil carb hasn’t been looked at in years haha!

Grab some Jerry Cans and go to your local airport and get some 100L avgas. Smaller airports will sell to you without wings on.
Another option is to get your gas at a Marina as boats with fiberglass tanks have been plagued with the same issues using Ethanol fuels.
Cheers,

The simple thing to do is to add the recommended amount of fuel stabilizer. Especially ! made for ethanol fuels. Brand names....Stabil marine formula, K100, Starbrite or Phase 4. These keep the gas and water which is absorbed from the atmosphere from separating and sitting on the bottom of your tank, floatbowl, etc.
I keep some in any equipment I have that’s used sporadically and for storage over winter, which up here is at least 6 months.

The gasoline is not contaminated until the tanker gets locally filled with gasoline down near Boston, then gets 10% E added and the blend mixes on the way to the dump site. (gas station)
The absolute last actual local gas station witn NO-E stopped in about 2006 here in Beverly Mass.
The reason Airports are shutting you guys OFF is it is illegal (in the US) to sell av gas for a highwy driven vehicle...no road tax. They don't want to run afoul of the US GOVT LAW.
I still buy at the airport and ONLY (really) use it for OPE.
What is happening in Canada and England is unknown and out of my control.

The majority of these locations are obsolete. My local NH airport still sells 91 and 101LL. I tell them it is for my Outdoor Power Equipment only, (true)
And the other verry few left are for VP racing or sunoco for big bucks and is still illegal to run on the road as there is no road tax. It's where the guys going to NHIS or Star speedway fill their race cars and cans. I will acknowledge the TX ones are much more current than here in the north east. Most of the local listing are way out of date....
Maybe it was a brit thing I saw proposing "preservation fuel". To bad the US corn lobby is too strong in the pocket of politicians to allow that.
Corn is for eating or drinking.....only

I have heard, but not verified, that E free fuel is available at marinas?

Best.

Here in WV you can get rec90 gas at Marathon stations. It's for recreational vehicles and is 90 octane nonethanol. Has its own pump and cost a bit more but worth it in the long run.

Paying the taxes doesn't bother me at all... I'm just sick of my fuel tank being used as a landfill. I believe I'll give the product MichaelB linked a shot with some ethanol free pump gas I've allowed to settle a few days and see how that pans out.
I'm going to run my old 932's until the goody is gone, and then I'll put some premiers or wassells whichever suites me at the time.
