I'm happy that the v-twin is going to be set free from its planned restrictions.Dyna,maybe MSD,will reverse the governor on these motors for the after market.It's been to long a wait for a easy mod for the novice to install. I've used Dyna on street bikes with good resultes.It seems to me the vtwin was detuned from the factory.They were probably scarred.I appreciate everyones innovation. Brushog
