the one I was referring to was the spark plug replacement pump as Pruster carried on his airhead BMW. Not the electric one which I , as you, carry on both of my bikes. Made by Slime. When you would pull the sparkplug to installed the hose and check valve, using your engine as a pump and would have to be turning it over with the starter. I was in wonderment of how that would drain the battery Vs how long it would take to fill up , say , a 4.00 x 18 tubed tire.
