The crankshaft position sensor resistance you are looking for is 192-288 Ohms between the blue/yellow and green/white wires at the 2-way connector block.

It is probably worth checking the resistance value when it is starting and running OK and make a note of it. Then check it again when the bike fails to start and the 12 error code is showing up. (Measure it with the ignition switched off though)
