I mix AV gas and 100ll at 50/50 and my bikes and four wheeler like it fine. AV gas straight in small motors I'm not a fan of simply because it still has lead in it and I've seen pretty nasty buildup on 450 race bikes that were ran on the 100 ll. I have not seen the same issues in my cr250 though. Might have to try some straight AV gas in my saw just to see the results. AV gas is easily bought where I live. I run my turbo sled on it and haul 4 five gallon race jugs out to the pump and get them filled regularly. I do live next door to a very small airport also. And I know the people working there.
