My after work night rides are not over yet, went out today in the neighborhood for about 5 miles. I could not believe my little bike would even run after going through the fuel system, the tank and lines were completely plugged with sludge. Used Simple Green to get the crust out of the plastic tank, worked pretty good, it's singing nicely now. I like to pedal with the motor off through the scenic MUP's, and power back up back on the side streets ( I even get a little exercise with it).
