I'm still not that good on motorcycle electricals, but here's my two penny:
- You can try to check if you get a dummy indication for the side stand switch (shorten the wires in the green connector).
- I don't know what is the right way to simulate the bank angle sensor, but it seems to me that you didn't give a good solution there either.
- So right now, as I understand it, you are in the stage of "cheating" the ECU, and only after you have settled into this stage properly you will it be possible to think about checking the classic troubleshooting scheme.
