I just got back from a very long ride on the 950A a few days ago and decided to give the 640A some love. 4th kick I hear a metallic clanging. I looked down towards the noise and saw the kicker flying across the floor, bummer. I put a new one on this evening and rode to the gas station on a flickering fuel light. I couldn't remember how long the light had been on, the mileage showed zero. It died a block away but I only had to push the last 10 feet to the pump still straddling using momentum. The tank holds 7.20 gallons in case you ever wanted to know.
