Hi folks - If you have a Doppler internal Rotor ignition for Aerox/Nitro/Ovetto/Neos/Booster etc AFTER 2003 (with catalyser) I want t know the serial number on the CDI. In point of fact I badly need to know the serial number on your CDI. If you have one - and you need to take a panel off and fiddle about to do it - there is a belgian beer in it for you. I am not kidding -
