I recently purchased a 95 Sportsman 400 2 stroke and I was trying to find out why I cannot get spark, which is why i got it for cheap, but i have rechecked ever single ground on the entire atv, checked all connectors and have even tried replacing the cdi box but to no aid I cannot even find the right cdi box. It has a new spark plug, solenoid, wires, and battery. Every light turns on, great compression, starters great, but absolutely no spark from plug. Any help is wonderful. I am stumped.
