2012 yz 450f. Went to start, nothing. Have another running yz 450f. Changed coil, rectifier, smoothing capacitor, ign box, spark plug cap, stator, and flywheel. New spark plug. Unplugged kill switch(left unplugged during changes). Got ohm meter and checked all this stuff with it. All good. Put non running bike parts on running bike one at a time. They all worked on running bike. Bought new wiring harness. Still no start. Looked at every plugin for bent or loose connection pin. All good. And checked with tuner. No codes. No fire at plug at all. Tried another new spark plug. Nothing!!!!!!!!!!! Any ideas????
Did not change temp sensor, throttle position sensor, airbox sensor or the two pressure sensors
