Hello
I just got a Kz 900. It was sitting in a barn and was pretty ruff. I was getting spark on all 4 plugs. Then for some reason, the middle two plugs didn't have it. I checked the points and both of them were sparking. Then checked for bad wires or wires unhooked and couldn't find anything. Can you think of anything or maybe a wire over looked.

Thanks

sosunds like one of the coils, the one that sparks 2 and 3 is dead. Use a voltmeter to check voltage going to the coils, and if voltage, check the resistance of the coil by switching voltmeter to ohm meter mode and pulling off cables 2 and 3 and check resistance between the 2 of them. They are supposed to have a certain amount of resistance, which I dont know, sorry I can't help you there. Primary voltage is checked on 2 wires going to each coil by the way! Good luck and happy testing. Also unless you have new sparkers I would change those ones.

try swapping the 1/4 coil for the 2/3 and see if it makes a differance;)
