So quick question. Has anyone tried the cdi box in the oven trick?  I have posted a topic last week on my 1990 Honda fourtrax. Picked the bike up cheap. Bike had no spark so I went right to the obvious suspects. Cdi, stator, coil etc.  Stator coil was coming back with good readings but still had my doubts and also wanted to change it for the learning factor.  Anyway no good. No spark and the new cdi is two weeks away.  So I remember watching a video on YouTube about putting the cdi on the oven on 250 degrees for ten min! Somehow draws the moisture out if any! I tried this today and to my surprise the darn thing came right back to life. 

So anyway just curious on the input on this. Would you change the box ? I resealed it with silicone? It's still working great and the bike is performing very well. 

Just curious on everyone's input. 

Thanks.

I've  never  tried it. Glad  it worked  for  you;  but  I'd  keep  that  new   box handy.  As  long  as you're  riding with  at  least  one  buddy  and  not too far  off the beaten  path I'd  leave  the resurrected box in the  machine.  It  may  live on forever  or  it  may   die tomorrow,  but that  can  be  said  about  just about  everything.

Yea i agree. New one going in as soon as I get it.  However this oven thing def worked. 

If your at a loss and not sure about the cdi bc we all know there is no way to really test it I recommend trying this out first.

      Winch question?
      By Tim Keiper
      I have a Yamaha Timberwolf 4x4 250. I want to put a winch on it, but just wondering if the charging system will handle it or not ? Has anyone added one to their machine and have you had any issues?

      2000 Honda 400EX Backfires
      By Trent Finnessey
      I’ve got a 2000 400ex with a dg slip on muffler, it came with he stock muffler on it but the previous owner had the dg in a box so I put it on. I’ve been riding it for the past month and a half and every time I let off it backfires, and the other day the backfires got way louder, 2x louder! I’m concerned that I may hurt my motor? Why does is backfire??? Thanks

      1999 Yamaha Big Bear 350 4x4 no spark

      Troubleshooting a no spark issue, was running OK, maybe a little rich, turned it off, now no spark. I've checked/ohmed out the main key switch, the start/stop switch, neutral switch, brake switch - all good. It will crank the starter, but no spark with the starter or when I try the pull start. I've checked all fuses and diodes. Swapped battery. New plug. New coil. Swapped in a used CDI - no help. Traced, removed, cleaned, reattached all grounds. Removed things like my winch from the circuits to be sure a bad relay or something was dragging it down. When testing voltages, the orange wire going from the CDI to the ignition coil shows no/very low voltage-shouldn't it have 12V on it? Sometimes I get a very weak, intermittent glow on my spark tester, but not enough to fire the plug. I've checked continuity on just about all wires in the harness. Checked/cleaned/lubed w dielectric grease- all connections, redid a few that looked old/dirty. I've checked the stator resistances, all good, but have a stator and rectifier ordered anyway, will arrive Sunday. I verified that the rectifier has a voltage output back to charge the battery while cranking - 10.5-11V, low, but expected while starter is engaged. What else can I check as part of troubleshooting? I have a Haines service manual, but the 1999 350 4x4 seems to be an odd model, there isn't an exact electrical diagram for it, but found one for another year that has all the same number of wires and same color wires, so I've referenced that. Any hints, tips or advice would be appreciated! Thanks!

      '03 Honda Sporttrax 400EX Carb issue.
      By Dumass
      My name says it all. I have a '03 Honda Sporttrax 400EX with a new aftermarket carb on it that seems to be having issues. I can start it but it idles really rough and when I give it throttle it just kills the engine. I have tried adjusting the idle screw but to no avail. I am in the San Diego Ca area. 
      Any advice will be greatly appreciated. I would also like to get an owners manual for the thing too but can't seem to find a downloadable one.

      1987 Honda TRX250 No Crank
      By Arizona
      I recently bought a 87 TRX 250 not running of course, the owner had a brand new Key Switch on it.
      I think it is the wrong one or wrong wire colors as the colors dont match up with wiring diagram i downloaded for it. 
      anyone have a pic of their ign switch wires where they connect with the wire colors for that model? I ended up leaving the black/w stripe and
      green wire disconnected in order to hot wire it for other testing but would like to know as the colors dont match diagram.
