Hi! Bought used Z650 2017 with mileage 36000. Sometimes expericence the problem that I can not start the engine after turning on the ignition. Behaves like battery is discharged (rapidly turning on-off starter motor, making 'clicking' sounds) though battery is fully charged (and actually was replaced to be on a safe side after couple of these cases). Pushing bike to 10-20 km/h helps to start the engine in the 2nd gear.

Did anyone experienced such behavoiur? Bike still on warranty but it happens so rare and they don't know what to do.

I have a similar issue. Sometimes when pushing the starter nothing happens at all! The lights are all on but nobody is home! I suspect that it is something to do with the engine immobiliser, as turning it off and taking key out for a minute or two then trying again sometimes works. Also, if low of fuel (less than a quarter tank) and on a slight incline it seems to think that it is empty and wont start. Walking it a bit then trying again seems to help, but is really frustrating.

I have a similar issue now
bike turned off mid ride today and wouldn't start again
gear indicator was showing " - - " and was blinking
starter made sounds but it didn't start, no matter if I put it in neutral or first (gear indicator was still showing nothing)

a few hours later it started again but it wouldn't start when it was cold in neutral while on the side stand, makes only a clicking sound

well now I'm afraid it will turn off again mid ride, I'll try to get to the garage tomorrow

I've had this problem ,I put mine in gear push it forward and pull in clutch then it starts. Think it is either the battery,solenoid or starter. however my batter charges up ok on my optimate charger .When lock down is over going to get my bike serviced if I find what the answer is I'll post it here.

Just to add my experience, I have a 2017 with 6.5k miles. I have a voltage monitor on the battery. It has been sitting 5 days and the battery has 12.4 volts with the key off. So I will start it. I turn the key on and voltage drops to 12.1 volts - makes since with headlight. When I try to start it, the voltage drops to 11.9 volts (no lower) and the the starter starts making a clicking sounds maybe 2 times per second like the solenoid is trying to engage but cannot. I put it in gear and just shove it once so the engine breaks free. Then it starts right up and the voltage goes right to 14.1 volts and I am good for the rest of the day with no starting issues. I do not have to roll it to start it and it can be in gear with clutch in or neutral once I bump it loose - and I mean super easy bump. So if your bike acts up, do not panic and try that little trick to get you home at least.

Considering my experience and what you have all shared, I will propose a theory and maybe we can all consider if it makes any sense. Assume the starter on this bike as designed has an undersized or defective solenoid that drops out when the voltage falls below 12 volts - a starter solenoid should not drop out at near that high voltage in my opinion. Before the starter motor engages the voltage is above 12 and the solenoid engages, that pulls in the motor, but it drops below 12 when the motor pulls high amps, that draws down the voltage instantaneously, the solenoid disengages dropping out the starter motor as it should, the voltage rises above 12 under no load, and then it all repeats itself. We only hear a clicking a couple times per second as we hold the starter button.

A fresh battery could maintain a voltage over 12 volts even with the starter motor pulling, but a 2 year old plus battery is not likely to be able to do that even though it is still plenty strong enough to drive the starter - and should be good.

I propose there is a flaw in the starter solenoid design. You can overcome it with a new battery every couple years, but a battery should be able to last as long as it can hold the voltage above 10 amps under starter load and that might be 5-10 years if you maintain your battery. If that makes sense, and if many of you agree, maybe we can ask Kawasaki to make it right.

Please share your experience; buying a $50 dollar battery every two years is not a big deal. What is important is to understand the issue so we can manage it so it is only $50 every two years rather than several hundred dollars to the shop or worse a stranded bike.

Thanks guys!
