Thanks for the information you have shared on your twin spark Ducati modifications. We have made the decision to do something very similar with our project bike. I am going to use the smaller CPR8E spark plugs and I will also be using the TCPIP4 Ignitech to adjust the ignition curve. I will let you know how I get on with the project. I have posted a copy of your picture of your twin spark head to my facebook page before remembering to ask first. here Welcome to Facebook - Log In, Sign Up or Learn More
