Well, happened day before yesterday on way to the weekly ride meet at local Harley dealer. First time in 50 plus years of motor-biking. Called my buddies, all 5 on Harleys...oh there is one Indian, and they rescued me with 2 gallons of gas free gratis from the Harley dealer. Funny feeling when it happens......you are still moving forward and you feel the bike going backwards. Anyway, my new fuel sender unit needs calibration, someday, because it shows empty and light comes on when there is about 3 gallons left. So, when I keep riding off and on and lose track of when it first went to empty on the gauge and, well, the rest is history. Need to get in the habit of eyeballing the odometer and zeroing it out at every fill-up. The Indian rider, 87 year old retired Korea era Marine, is giving me one of his gas bottles next week......holds maybe a pint of gas. So, next time, if I can remember the bottle in my saddlebag, I can go a few more miles in search of a petrol station.
