In this category you will find all the capacitors we can have for your motocross HUSQVARNA like FC 250, FC 350, FC 450, FS450,... What is the purpose of a capacitor? It allows you to start your motocross bike equipped with an injection system to start your engine by pushing or kicking. How does it work ? Even if the battery is tired, there will be enough energy in the capacitor to maintain a correct injection even with a weak or dead battery. How do I know if my capacitor needs to be changed? Simply take a voltmeter and set it to OHM. If the values are lower than those announced in your technical review, then it is surely to be changed.
