CDI ignition

[Frank Angerano]

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.

Not sure if you have the service manual , but I just restored a 2001 Kawasaki Prairie 400 2X4 with CDI problems. The service manual had a chart with the CDI Pins and what you should see on your Test meter when touching every combination of the pins.
