86 moto 4 cdi

It’s hard to say but I would guess the last two years before and after would fit that. Just look up the part and compare the plugs. They should be noticeable as far as fit up.  But before you replace everything do some testing and check the stator and pick up coils first. If your handy with a tester let us know and we will walk you through it.

Just FYI...I have the same machine and my spark issue was caused by the ignition coil mounted under the gas tank where the spark plug wire comes out of. I replaced it with a new one from Partszilla for under $20 and it solved my problem. I don't know about the CDI.

Mine lost spark until I charged the battery. I figured out that the voltage regulator/rectifier was bad by using a multimeter. I tested voltage from the stator at the connector the regulator plugs into, white wire to blue wire. You should see at least 12 volts AC. It should go up higher than that when you rev the engine (mine goes up to 30 VAC). If that's there, you have a good stator. Then test the regulator/rectifier, which would probably be best tested by connecting your multimeter to the battery with the engine not running, and note the voltage. Start the engine and rev it up. The voltage should go up. If it doesn't, you need a new regulator. The inline fuse is part of this circuit, too, but nothing works if it's blown.

For you electronics nerds like me, I test the regulator output at the battery because the raw feed from it while disconnected from the battery can confuse some multimeters because it's pulsed DC, not constant DC.

There are only a couple of years that fit the 86. They used the same CDI for the last 3 wheelers and first gen 4 wheelers. They are very rare indeed.

      I have a 1996 Kawasaki Mojave KSF250. I have no manual on it and it has a no spark issue. If anyone could give me a hand with this or would possibly have a manual would appreciate it.

      in this thread, I want to discuss how 4-cycle atv engines work- what the different types are...  how they are set up and which you prefer.  To start off, are the cams on ALL atv 4-strokes powered by a cam chain?  I know that on say a lawn mower or logsplitter engine, the cam is turned by the tappet, pushrods, and valve rockers.  Which is better and why?  Chain-driven cams or pushrod-driven cams?  Are the pushrods just an old version and everything is transforming to chains or the other way around...or not at all?  Just looking for some explanation, history, and downsides/upsides...

      I have a 99 250 Quadrunner. Currently has no spark. It would run for 5 minutes, then shut off. After it cooled down about 20-30 minutes, it would start again. I ordered a new stator and found the old one was damaged (copper windings broken)  I installed the new stator, filled with oil and now it has no spark. Any assistance would be helpful

      Hello I am new to this site and I havea problem. I have a 1987 big bear 4x4 that will not spark. I tested pick up coil per repair manual and I tested my new coil both ok. It puts out 9 volts at the coil but It is reversed polarity. So when I hook my meter up to it she shows -9 volts while cranking. When I put a test light  on it it flashes. Being an electric system this should tell me something but I don't know what its telling me. I have yet to meet one i could not fix but this old girl has me stumped. Any help would be awesome. Thanks to all.

      I’m working on a Kawasaki Bayou KLF400 for a family member that doesn’t have spark. I’ve already replace the ignition switch and the stator which were defective. The stator had a melted connector and one of the phase had low resistance and low VAC output. 
      What I’ve figured out so far is that I’m not getting 12V to the ignition coil when I turn the key to the ON position. From what I understand, the 12V should come from the CDI. I’ve resistance tested both wires going from the CDI to the ignition coil (Green/white and black/yellow). They are fine. The only 12V coming from the ECU is on the yellow/red wire.
      I don’t have the wiring diagram for the 400 but I’m working with the one for the Bayou 300 which looks pretty similar except for the wire color between the CDI and ignition coil. On the 300 diagram, the yellow/red wire goes to the ignition coil, not the black/yellow… All the other wires color match except for this one. Not sure if that’s normal?
      Thanks!
