I had a look at that but it was a little more complicated than my small device. In the meantime I found a short video that did a very nice explanation. I think my primary has too much resistance and thus the amount of current is not enough to create a strong secondary pulse. Thanks for the reponse.
I have a 1999 Lem ATV that I believe has the same engine as the Lem motorbike. I am replacing the ignition system with the PW50 Black Dragon ignition kit. It seems to be easily done but after installation there is still no spark. Interesting enough is the fact that the kick start is done down...
