Mine did the same thing once. Ran great, for a while, then would drop the right cylinder. Pick up was fine, got a Procom box. Worked great for about 5 years. Then one day it gave me fit starting it. Had to push start it. Ran the tail of the dragon fine and would intermittently drop the left cylinder on the way back, 800+ miles. Bought some Nology coils to replace the stockers and it ran great the following weekend. Went to go out on a ride 3 days later and it had no spark. CDI box was dead. Got a TTP firstarter and it fired right up. The Procom box just died all of a sudden.
