Installed the Procom CDI the other day. Finally got to take it out for a ride today. What a difference. So far after my first ride it feels as though it was worth every penny. Set it on #6 ,it's like a different bike. Can not wait to get the time to play around one day and try a new program. Bike has K&N's ,rejetted, aftermarket freeflowing mufflers,and a few other mods.
