In this category you will find all the capacitors we can have for your motocross KAWASAKI like KX250F, KX450F, KXF 450, KXF 250,... 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.
