The solenoid has absolutely nothing to do with the spark. You could be looking at a bad coil ( the one of your recon may not work on the this quad), bad coil wire/plug boot, bad plug, bad stator, sheared flywheel key. If the 300ex CDI works, then you will know that you need a new CDI, otherwise, I would check the list of manuals that Rocky Mtn Honda has posted in the Honda forum and see if your model is listed in there. There are some tests that you can do on the electrical components so you can find the faulty part or at least rule some things out. BTW, I am moving this thread to the Honda forum, for some reason it is in the Yamaha forum now.

Don't forget the simplest things first.  1997 Fourtrax300FW was running fine, stopped it to split some firewood, wouldn't start back up, plenty of fuel.  I pulled the sparkplug, zero spark.  I read a couple forums which made it sound like the most common problem for no spark was the CDI.    From a YouTube video, I followed the instructions and used the multi meter Ohm meter to check the resistance on the two coil leads and the reading was about 0.8 as expected for a good coil.  Ordered a CDI, replaced it, still no spark, but when I was checking it I noticed I was getting a shock holding onto the plug wire.  Used a multi meter to check the spark plug (from instructions on YouTube videos) and there was no continuity on the spark plug.  Replaced the spark plug, turned the engine over with the plug grounded to the cylinder head, visible spark.  Then reinserted the plug, and it started right up.

The moral of the story, if you don't have a spark, you may want to check the plug, or replace it first.  That was the cheapest option, and it would have saved me the time of pulling the front cargo carrier and plastic off to get to the CDI, and order and pay for the CDI.  I hope this helps someone else down the line.

      Couple of quick points:
      1. the Odyssey, or FL350R. This was 30 years ahead of it's time.  Fast as greased owl crap, reliable, stupid fun.  Never took off.  Fast forward to the RAZR which was just replicating the FL350R.  What would Honda have done with it if it took off in '85?
      2. Everything about the ATC.  Reliable, good power for small displacement, easy to work on, simple front to back, still running 30 years later.  My son's 185s is 36 years old and outran a 400 Big Bear the other day until it ran out of gearing and the Big Bear caught it around 50 mph.  I can dig a 110 out of the weeds and as long as it has a little compression, I'll make it run in 2 days for about $20.  Can't do that with a Yamaha 225.
      3, 1981 250R.  What happens if you stick a CR250 2 stroke in a trike?  Yeah, a death machine.  Then by '85 the 250R had a 6 speed and would do 70 from the factory.  Death Machine +2.  The 250R gave birth to the trike racing circuit.
      4. The ATC 70.  Small, quiet and reliable.  Just never took off.  Gave birth to the entire small displacement chinese quad market.
      5. 82 200ES - first Big Red.  The BR single handedly created the UTV market as we see it today in the Ranger, Mule, etc.
      6. The ENTIRE chinese quad market in front of us today came from expired Honda patents from the 80's.
      7. 300 fourtrax.  By far the most coveted 4x4 in the market right now, absolutely indestructible.  Pick one up a couple of years old, stick massive wheels and tires on it, and you have a mud machine.  Kinda like the Polaris or Can Am...but reliable.  And cheap.
      To be fair, Yamaha, Suzuki, Kawa, all picked their game up along the way and make good ATV's.  I'll leave the Polaris/CanAm discussion for another day.  While Polaris gave birth to the automatic, the reliability issues of both still exist today.  While great ATV's, I don't consider them any more than specialty machines.
      FIGHT ME.
      or debate...whichever is easier.

      I recently purchased an 07 Honda sportrax and when I was checking the spark plug I saw the boot was ripped nearly in half. When I removed the plug it was blackened and covered in oil. How can I thoroughly clean the plug hole and remove any debris that is in there? Is there a small tube like vacuum or something of the sort made for stuff like this? The machine my dentist has would be perfect, maybe they do rentals! 😁
