2001 yz426f still no spark.

Cdi changed. Grounds checked. All electronic components check for proper ohm readings. All wires checked. Tps checked. I have signal from the stator pickup to the cdi but nothing past the cdi. Please help.

Wow...nothing. that sucks

If you have checked all three coils on the stator (source, exciter, and trigger coil), the ignition coil, the TPS, and the kill switch, and you have tested each of the wires in the harness for continuity from end to end, then it's likely to be the CDI.  But only if.
