My son has a moto 4 225 with no spark. I though the problem was the CDI after replacing it still no good. the coil is testing good at 15.6 ohms. not sure about the stator or the pulsar. any body have any hints on this?

 

Follow the manual on testing for spark. Make sure you always have a ground to the spark plug threads when testing. I have seen ungrounded spark plugs kill a brand new CDI.....

 

I have not bought a manual yet. I hoped to have more time to find one. It has been broken longer then we had it.
