Swapped the Darkhorse compensator back to the stock compensator. Fixed it.

Rode the bike for 17k more miles after this before I sold it this summer. Kinda crazy sounding but true.

All I could ever conclude is that POSSIBLY the ecm didnt detect compression because the darkhorse comp allowed an older engine to spin over more quickly, therefore the ecm cancelled spark when it detected this. Thats all I could figure. I even talked to the DarkHorse patent holder and Fuel Moto extensively about it all. No true explanation was ever figured out. All I know is the compensator was my only factor that had changed, and ultimately had to be swapped to fix the problem
