2005 LTZ 400
Ran for an hour, backfired and now wont start.
Has new stator, coil, plug wire/boot. Checked EVERYTHING from the battery up ( CDI, Resistor, fuse, etc. ) No spark from the plug (new plug).
Getting fuel, so thats not the issue....HELP!?

 

Maybe make sure the motor is grounded to the frame.
Sorry, not my machine. Wish I could do better for ya.

 

I'd OHM from the stator and work your way up...electronics can fail...even new ones...
