So my bike was working fine. I was running with only a rear lambda. Parked it one night and next day plug in a newly received lambda for front that I got on eBay. Went to start and it would not catch. Eventually drain battery. Buy brand new battery and find out that it wasn't the issue. I checked the plugs and they won't spark even tried an old coil on front and back and nothing. I also don't think it's sending fuel in as I don't see or smell anything when I crank with plug out. This thing was running great before I plugged in that lambda. Could it have ruined something???
No spark on either cylinder. Cranks but no boom.

My last no start scenario was different (no crank, CEL/ ERRORS would flash with starter thumb), but I'll give you some things to check. There's some starter/ battery related relays near the battery. Not sure which one as my mechanics English is not so good but he said a relay was faulty due to my Lithium battery. I don't think this was the problem as I found a bad lead to the forward fuze box was causing the no start. The bad lead would actually kill the running engine too.
Not much help but good luck.

I've ordered a new crank sensor to see if maybe that's the issue. Won't be here for a few days though
Another symptom it cured was the slow starting! My idle was also kind of erratic and not stable. Also I had several occasions where the motor died while on free way. All lights and dash on but it's like someone hit the kill switch. It maybe was the sensor this whole time

My sensor had 60k on it. It's somewhat easily accessible from the left side just remove one bolt that's a little cramped and it'll wiggle out with some persuasion. I just cut the old sensor wire so I would not have to remove things to pull it out. And I routed the newly installed sensor differently. Over the top of the coolant bottle.
Also my kickstand sensor just began failing and was causing the same engine kill symptoms I described while on freeway. Plugged up a dummy connector with jumper and it cured it. Definitely starts easier with my new sensor and it was a used part off eBay at that.
