Aside from some standard tools - the only thing I'd recommend you have is a timing light. They recommend taking your gas tank off to connect/splice to a wire (Black/white stripe) with a connection they supply. You have to remove the points cover, remove points plate and advancing mechanism - install a magnet device on the advancer, then the electronic ignition, and connect electrical. Put tank back on and set timing. All of this is explained in their instructions - takes about an hour start to finish.
It works with stock coils - I upgraded to Dyna 3 Ohm coils a year later. Only because Uncle Sam paid me to - never had a problem with the stock coils.
