Thanks to this post by TwoTired ----->
http://forums.sohc4.net/index.php?topic=17711.msg184209#msg184209 a year and a half ago detailing a methodical approach to testing electronic ignitions and coils, I was able to determine why I lost spark in #1 and #4 on my 750 riding home last week.
Turns out the 30 year old Martek 440 stopped firing 1 and 4 on me. This post by TT allowed me to quickly determine that my coils weren't the problem and that the wiring all the way to the Martek would create spark in 1 and 4 plugs. I replaced the Martek with a used set of points, dressed them up, set the static and advanced timing, and away I go.
Thanks TT!
