I wanted to change the points on my old Yamaha RD400 to something without points and maybe a hotter spark. Surfing the net, I found what I wanted at http://ignitech.cz/english/aindex.htm The unit I bought is a CDI which is good for a two stroke, but the best thing is that it is easly programmable with a windoze based PC, that is the only thing I have against this unit, they don't have a Linux version of the program and it won't run under wine (windoze emulator).
The pictures are from my RD installation, but this ignition can be adapted to anything. My unit has two channels, therefor two pick ups. Each pick up can be trimmed by software independently from the the other so it would work quite well on an ofset crank. A regular Norton could work OK with a single channel non CDI unit (Sparker TCIP4). They use inductive pick ups, but they told me it would work with any type of pick up (optical, hall) I chose the inductive pick up on my Yamaha because I didn't want to run extra wires down to the end of the crank, with the inductive pick ups, I could use the stock wiring. There are also programmable inputs and outputs, for example one of the outputs could be used to turn on a light at a specific RPM, or if you wish, a shift light. The shift light could be linked to one of the inputs to kill the ignition for a few revolutions to shift without a clutch by just preloading the transmission so as you reach the set speed, the bike shifts, that could be hard on an old girl, but it just shows what can be done.
Here are a couple of screen captures of the control program with the bike running, the ignition curve can be custom tailored with the click of a mouse, just pick a point and move it up and down or left and right. The rev limiter can be adjusted to any value. The green line on the graph shows the current engine RPM. A very cool product, well worth the extra cost compared to anything else.
