weird situation. a few weeks ago ATV was running great (Zebra 250). went to start it the next day, no start. tested spark at plug. no spark. got a coil off ebay for 10 bucks. still no spark.

went to try it again yesterday and it fired right up. the only guess i have is that we had a bunch of rain/snow (about 10 days straight) and something got wet (i'm guessing the CDI). after some nice dry weather whatever was the problem dried out and it fixed itself.

the CDI is a 3 plug, 7wire unit (not a common one for sure). i thought about undoing all 3 plugs and using some dielectric grease on the plugs to keep moisture out. any other ideas of what i could do to prevent it from happening again???

thanks! scott
