i've had the same dyna s on 3 bikes now, still works perfectly, the 2000 is more of a race piece i've been told. also been told that you need to run a 3 ohm coil with the dyna s. the stockers are 5. over time the difference will cause damage to the ignition i'm told by ken at cycle exchange. the money spent on the ignition is so well worth it. theres one less variable (points) when tuning your bike now.
