All spark ignition bikes have coils; it’s just what triggers the spark that varies. I’d swap back the spark plug; I tried an iridium in mine and it fouled. These are really meant for engines where you need a mining degree to remove the plugs and they can foul easily if there’s anything wrong with the ignition or fuelling. Also, you should here the pump prime, then stop.
