In the morning:
1. I get to my bike, flip the gas levers to "on" for about two minutes before starting.
2. Crank the...urr, choke lever all the way, and start her up.
3. This first days initial start bellows out a light blueish smoke just for a second and then it clears while the engine idles healthy and sound.
4. Throughout the day, during any other start-up, THIS DOES NOT HAPPEN. Only occurs on the initial start-up when the gas has been sitting in the carbs for 8 to 10 hours.
Question: Is it perhaps the gas left in the carbs overnight? Does it indictate poor gas? (I have been using 87 octane, 10 % ethanol) OR is this normal on an older Airhead?
