hmm, not sure what to do. i have five gallons of it sitting in my garage. i too am a pilot and heard all of the reasons: high altitude additives, it burns hotter, it burn dryer, its made for low compression engines, etc. but, i did use it in my two stroke for years and did no harm. a friend of mine used to work for boysen and dyno'd fuel. he found that av gas was within half a horsepower of the top fuels at the time, circa mid 90's. im just wondering if its gonna hurt it. i think i will try half and half.
but when i went from pump to av on my two smoke, it made a world of difference. it only made it run way lean, which it will do on any bike. thanks for your imput guys!!!
