Hi,

I have an 2004 xb12s which is an awesome bike.



But, approximately one out of every four times I try to start the bike, it doesn't respond to the starter button.
All is normal, i turn on the ignition key: headlights are on, I hear the fuell pump for a few seconds, three lights come on onto the display, one goes out after a few seconds (the engine light), all normal. And then.. nothing when I push the starter button.
Also no sound or relay click at all. Absolute silence.

Then when I turn off the ignition key and switch it back on, most of the times it does start and after that all is normal.

It doesn't matter if it is a cold or warm start.

Sometimes it doesn't start a few times in a row. I get the impression it makes a different if I put the bike in gear and push it a bit front and back so that the crankshaft rotates a little. But I'm not completely sure this is the case as I have tested it only a few times and I am not sure it is a pattern.

Where to start the diagnosis?
