    I've been running 100LL for years. Mixed with UL Premium at different percentages and also straight. All my bikes run perfect.
    Used to put it in my 1969 Cadillac Coupe DeVille (472 CID) at about 25% 100LL with Shell UL Premium and it ran like it had time warped back to 1969 and got a fresh drink of Sunoco 260.
    We had an area Sunoco Station that went out of business about 20 years ago, they had a 94 Octand UL Premium at the pump. After they closed, I switched to the 100LL
    Luckily, in Indiana, we still have access to premium without ethanol. For how long, who knows. Over the years, I have personally worked on bikes that were brought to me with problems and many many times, returning the jetting to the correct range and changing the gas fixed it. It is my experience that you cannot correct junk fuel with jetting...

    As many here have said, it's all about trouble free fuel delivery. My biggest concern when the bike has sat awhile is if oil has separated in the carb bowl. I switched from maxima to golden spectre to help.

    That is funny. I have not used Golden Spectrok since I sold my MAR Ossa in '76. I have been running Super M for one reason ever since. The little guys riding out of our shop on RM 80's. I got to see the inside of rhe motors regularly. Became a believer in Maxima, and they continued on to race Arenacros and Supercross as adults.

    All oil will separate in the floatbowl after awhile espec if it is hot because the gas evaporates.I have been taught since I was a little kid to turn the gas on give it a shake and lay it over to get some gas in the bowl.If it has been idle for days.Av gas is great as a mixture to prevent knocking never had a problem with It.Never used it sstraight.Everyone has their own ways that work for them.No worries!

    Avgas is just high quality gasoline. It's a little less dense than pump and might affect jetting. We all run it in our 2 strokes including my wife's GasGas contact. They're usually all jetted rich and throttle response is better. The rumors of less power and blah blah is all just rumors. For years it was the base used in all race gas.

    Around here it's the same price as premium non ethanol and the local airport is on my way to work.

    Some 4 strokes are jetted lean and avgas will make it worse. In my wife's last bike it would run lean with a white plug on avgas but ran fine on premium non ethanol. Lead is good for motors and was phased out due to epa not because it didn't work.

    By the way last weekend I tried Bene's chain lube thread idea. Food grade chain lube. It did work pretty damn good. Of course I got it for free.

    Yesterday Brewtus the landscaper was busting his ass trimming the sections for the Roswell Nationals. Luckily he lives in that crappy Texas town. Otherwise he would be driving home in the snowstorm with the boys! Surprised he had any energy to chime into a fuel thread.

    I knew what he used to run (In Albuquerque), but now he is probably trading for it straight from the source. We will see you the 17th.

    Alpineboard, I see you repeating this in a lot of threads. My research shows everyone of your claims to be false. So please post some sources to backup your claims. My sources that dispell your points are below.

    "Low lead by Aviation standards only, it actually has approx. X 10 or 20 the lead that was in gas in the 1970's"---

    Not true. Gas in the 1970s had 2-4 grams of lead per gallon (http://www.ethyl.environmentalhistory.org/?page_id=27). 100ll has 1-2 grams per gallon (https://en.wikipedia.org/wiki/Avgas#100LL_(blue))

    "AV gas has a grid type carbon chain which gives it a longer burn time for use in Airplanes"

    Not true. The carbon chain in AVgas is 4-12 molecules long.(https://www.repsol.energy/en/products-and-services/aviation/avgas-100-ll/index.cshtml) Automotive gasoline has similar chains at 7-11 molecule carbon chains (https://www.ncbi.nlm.nih.gov/pubmed/26415451)

    Don't make me show everyone your picture now... :lol3

    Your old 304 will get the same fuel I run in the rest of them, 100LL Aviation fuel. Don't care what folks think about it either. :D
