Stator likely the culprit? If its not recognized by the ECU, the sparks won’t happen and also the ECU primes the pump directly.
Also look at your clutch switch (don’t bypass it as fake neutrals can happen) , neutral sensor ? , Side Stand Switch (bypassing it is OK as it is a very annoying object) = These would stop the ECU priming the pump or sending sparks.
If not, you will have to strip the bike down and carefully go through the entire harness making sure there is no dead circuits from one end to the other end of each wire.
Contact Cleaner helps keep the connectors in good condition with air compresor jets on the wire connectors.
ECU = Just blow air and don’t put any liquids on it.
Hopefully we get somewhere?
Also check your RO-SENSOR (Tip Over Sensor) = If bike can’t sense it or thinks you fell down, it will cut sparks off.
This PDF by another member helps go in more detail also:
While the harness is apart , get a meter and use the service manual on this forum to test every sensor connected to the bike (ie. if something says 0 ohms where the manual wants 20 ohms, that object is either faulty or connectors are bad/too oxidized)
Kill Switch Plug (where you press start) is also crucial, make sure that right handle bar switch cluster is fully cleaned out including the contacts inside the switch rockers and the actual black plug under the airbox
