glen, my egli has twin plug heads and a kirby rowbotham ignition system (except for the coils which are some great big clonky american things) and it has been 100% reliable. That system was already on the bike when you rode the bike with you massive size 15 boots resting on the rear brake pedal! I still have all the paperwork that came with the system so maybe I can scan it or something, anyway it is very straightforward so give me a ring and I will try to help.
thanks
mark
