The ESI 530 should be trustworthy. What is the peak voltage of the CKP sensor measured at the ECU connector? What was the peak voltage at the ignition coil before it lost spark?   I've been too busy to chime in up to this point, but I'll try to check back here a couple times a day. Odds are we can fix it.

I have a true peak voltage meter, I never trusted the adapter that I bought. I bought an ESI 530 DVA multimeter hoping for better results. Running the troubleshooting that Honda has outlined. Originally this problem would arise when the machine reached operating temperature, but it will not start at all now. No spark! I now have no peak voltage to the coil. Nothing. I have wiggled, pushed and probed the ECU connections. I have voltage at the black/white wire of the ECU, from what I can see there is connection of the green ground wires to the ECU (continuity between those green wires and the frame with the key on or off), appears as if the gear position switch is working correctly since it shows all gear positions. I have checked peak voltage from the new CKP, first from the plugs at the ECU and PS module, then at the plug from the CKP as Honda recommends. Both readings are in spec.

first problem is you used china parts !. honda atv's do not like china parts at all. second: you got air trapped in the lines.

@ATC4ever I replaced the shift motor recently, but just to check my wife has the same bike so I took her shift motor off her bike and tried it on mine and it does the same thing.    @TBRider I have replaced everything with Honda parts.
