Hi Hooper, Im in sorta nearby Camarillo. heres a link to a page with links to the instructions, I don't know which version you have so you have to scroll down to the bottom to find the different instructions. http://www.dragonfly75.com/motorbike/JNM/CDI.htm
If you are ever in my area and want to go out for a ride with someone let me know.
It has two sets of jumpers, 0+1, 1+2, or none. One will adjust the curvature of your ignition sequence, the other will adjust initial timing (but it will still be on a curve). You'll have to check that site, but jumper A is the initial timing
