Intermittent No Spark, Bad Relay?

50% of my starts have no spark either cylinder. Cycle the power, and the bike fires right up. Is this a sign of a failing relay? 2003 vstar 650 custom. Has new oem pickup coil and stator. Igntion coils ohm out slightly high- 17kohms. I think the limit is 15kohms?

Probably unrelated but I think I should mention: Bike only has 1/4 throttle under load and tops out at maybe 50-55 but I believe this is carburetor related and not ignition or related to start problem (hopefully). Engine has full RPM range while not under load (in neutral). Suspect diaphragm issues, and will be testing with a separate rebuilt carb in a week as I've given up tinkering with my original carbs.
