250sx spark problems

[Rockthunder]

I have no spark on my 250sx and have tried everything I think. I have replaced the spark plug, cdi, coil, stator, wiring harness and still no spark. I have also unplugged the start switch still no go. Are there any tests that you can do with an ohmeter to check the parts? Anybody got any ideas? Very anxious to ride my "new" bike. Thanks!!

do you need the wiring diagam ? i can send to you but would need you to personal message me you e-mail addy. i can send full size that way and easier for you to read/follow.

try removing the cover from the CDI make sure the shaft is turning when you crank the motor,it tells your coil when to spark :(

The 250sx don't have the CDI on the Cam Shaft. It's on the crank. I would say check the wiring harness for breaks or bad connections. Then check the CDI box, Stator, Ect.
Hope this Helps.
