86 moto 4 200. No spark. Plan to replace everything from stator to spark plug. 

Can anybody tell me what years/models cdi box would work?

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.

      Fixing for a friend. Atv was at a different friends house to be fixed and he rebuilt the carb and had it running nice, then it shut off and no more. He replaced the key and the coil.
       
      So he got busy, so I am helping, I checked the wiring from the stator to the cdi, and from the cdi to the coil. All is good. I checked resistance on the pickup coil, good, and on the source coil, open. I buy a new stator (China) and the 4 prong plug only has 3 wires in it while mine has all 4. I checked resistance in the source coil and it's in the 300's. I pulled one of the old pickup wires out of the old stator and wire it in the new one. Still no spark.
       
      Why do the wires differ, I checked the VIN again and it's "J" for the year and I got a 1988 stator. Please help!

      Can anyone recommend a good shop in Winnipeg, Kenora or Thunder Bay to rebuild / rewind a bike stator?

      Hi All,
      Following on from the brief interlude in the "introducing myself" thread....
       
      In a nutshell, I acquired a YFM250 Moto 4 (1991) for cheap recently with the previous owner citing "no spark, needs a new magneto coil and I don't have time to fix it"... anyway I am dubious that the magneto/generator is the issue and thinking more along the line of ignition coil as after a clean up of the magneto I was able to get a rather decent voltage reading off the magneto with pull start and resistence readings seem to check out that the magneto is all ok (all 3 x phases = 1.2 ohms and no run to ground)
      None the less I ordered a new Ignition coil and Magneto/generator coil and am waiting for them to arrive.
       
      In the mean time I cleaned up the current Magneto, popped in a new battery and sparkplug, checked out all the wiring harness, all seemed good except I came across the "neutral switch" wire was broken.
       
      After wiring up a new neutral switch wire, the neutral light now comes on  (small win) and the starter relay (attached to rectifier) now clicks. If I hit the starter switch on handle bar the starter motor spins and if I  pull the cord starter I get a spark on pull....YAY!! I'll try and attach a video below if possible.
       
      So onto the starter motor. Starter solenoid seems to work A-ok, even if it looks crappy and starter motor spins as it should when I hit the start switch....but here is my issue.
       
      When the starter motor runs it turns Cog #1 and Cog #2 (see photo below)....but the chain in the back of the starter which I assume is the timing chain, does not move and there is no apparent movement of the piston in the cylinder.
       
      If I turn it by hand (per photo) or with the pull starter however the chain moves and the engine turns. However cog #2 rotates but not fluidly with the "Crank" (part I turn by hand) for the lack of a better word to use if that makes sense?
       
       
      Is there a grub screw or similar on Cog #2 that fixes it to the center shaft to make it all turn when the starter motor is run? Could there be a part missing? Previous owner had the starter apart so could be possible?
       
      The outer/front part seems to be on a key-way so not sure how to remove this easily to check how Cog #2 is attached.
       
      What am I missing here?
