my son has a kazuma 110 and about 8 months ago it quit runnin just stopped i checked it out there was no spark so i changed the ign.coil and the c.d.i. box it came off another 4 wheeler we had not a kazuma but everthing is identical does anyone have any ideas which way to turn from this point

 

On the CDI, the bottom row should have 3 wires, the top should have 2, the middle bottom one, take it out & check for spark again, this is the kill spark lead to turn the machine off, if you have spark after taking this bottom middle wire out, it is most likely a kill switch, meaning the left hand kill or the key switch or any pull tethers it may have. If it still does not have spark after pulling this wire, it is most likely the Coil or the Stator, because you already changed the CDI so its not that. Hope that helps.
