I recently bought a 98 yz400f for a $700. The bike had no spark but for $700 I thought I could easily find the problem and already be riding the thing. I started with the kill switch, that wasn't the problem. New spark plug...nope. I tested the stator and the numbers seemed to match what the manual said. So I bought a new CDI and a new Coil, put them on and...nothing. Is there anything I'm missing? Any help would be greatly appreciated! Thanks!
