Mine is behaving similarly now. For the last week or so, it won't start in the morning, starter motor will not engage, relay clicks though.
First time, I figured maybe I had a battery drain, it had been sitting for a few days, and it's getting rather cold. Tried to pop start it, flat ground and gravel, no luck. After that it started fine with the push button. Rest of the day it started up just fine.
Next time it happened, I held the start button down, and after a few false stutters without the starter motor engaging, it fired up. Rest of the day it started without issue. This same behavior happened on three or four more days.
Today it's just flat out refusing. Tried to pop start, tires are too cold, just locks and drags. I'm locked outside my friends house who headed off to work before I tried to start the bike. No access to tools till she gets back, but plenty of time for brain storming, I guess.
