I have a 99 speedster, ran great every year but all of a sudden this year there is no spark on both motors. I checked all fuses and all check out. cut a bit off the plug wires and still nothing. checked all the connections and all are good with no corrosion. used only in fresh water for the last 4 years so everything is clean and no corrosion. The only thing I can think of is stator or mag, but find it strange that both would fail at the same time... any ideas?
