I have a 97 sportsman 500 and an 02 for parts that ran until engine blew. I have changed the cdi box the voltage regular the pickup coil and the starter and fly wheel 1 cdi i get no spark at all and the other one i get 1 spark when i let off the start button. There's no power to the cdi box idk if that's an issue but i cannot figure this out please help. And for the longest time i could cycle the key on off and it would start and work and it won't do that anymore. The ills fly wheel had a magnet off could that have wrecked both cdi boxes? And would i get spark If the regulator or the reverse rev limit was bad?
