$5.20 a gallon? You got ripped off. I just picked up 20 gallons of 100LL for $3.85 a gallon. I have run avgas for 20 years in all my two stoke bikes. Stock and modified. Avgas even gives the stock two-storke bikes a boost. The mith that avgas is made for hi altitude is bs. Its good at not ever vapor locking and planes always takeoff at full power on the ground and then idea back when in the air. The LL does stand for Low Lead but has more lead content then regular pump gas used to have. Also the lead helps keep your motor cool.
