The Harley Davidson motorcycle engine is over 100 years old. The design has been changed, tweaked and modified the whole time. People have had their own opinions after every single one, yet it has survived no matter how negative those opinions have been. Water cooled motors, which Harley already produces by the way, are just another in the hundreds of changes the motor has gone through in its century old evolution. To me its no big deal, and I will not miss a nights sleep if they all change over next year. Sorry if it will ruin some of ya'll's beauty sleep. I know most of ya need it.
