Distributor to electronic ignition
 

I have a 93 model carb Suzuki 800. Want to make an electronic ignition kit for its 3 cyl engine. I knw there are some available in the market, but thrill of diy is something else altogether. So I will make my own. I can use the existing distributor for a basic electronic setup.

Also planning to put an extra spark plug in the head to make it twin spark. So want to knw what additional treatment will be needed. Thanks in advance.
