EDIT: SOLVED. I want to leave this up here for anybody else that it might help. Tip sensor was installed upside down :). I thought it was just another relay of some sort, but there's a tip sensor towards the top of the tank near the flasher relay. Once I righted it, all was well. Have a good and safe weekend errbody.

Hey All,

Having some difficult-to-diagnose starting troubles. This is a U.S. 2017 with ~4000 miles.

I'll give you the timeline:
  1. Yesterday, I left ignition on at work, had to get a jump. Rode home no problem.
  2. New parts had arrived, decided to install them. Don't think I did another start after the jump (oops).
  3. Installed new air filter and booster plug. Buttoned up and went to bed.
  4. Bike wouldn't start this morning. Tried several times, then noticed the vacuum tube at the rear of the tank was disconnected (oops).
  5. Reconnected, still wouldn't start. Tried several times. It cranks fine, battery is good.
  6. Finally started for like 2-3 seconds, then died. I got this result one more time later on.
  7. Removed booster plug and re-installed back to stock.
  8. Checked all fuses (they're all at the front left, right? no hidden ones?)
  9. Still no start. Disconnected battery for ~30 mins, still no start.
Here's what I'm seeing:
  1. Battery voltage is good. Left on a tender for a few hours, 100%.
  2. Cranks well, doesn't seem weak, though battery died after ~20 cranks.
  3. Air filter just drops in, so I don't think that could be installed incorrectly, causing an air blockage or something.
  4. Haven't checked spark.
Seems like a fueling issue, maybe? When ever I pull the tank, there's plenty of gas in the fuel line. I'm at a total loss. I've always done my own work on bikes and just don't know where to go from here.

Tried the odometer-two-button-press to get any error codes, it just goes to the rev counter. Started looking into Kawi-specific obd2 tools, but didn't want to pull the trigger yet.

I'm pretty surprised that I managed to get a no-start scenario with so little tinkering. It usually takes me a lot more :)

Anyway, it's labor day weekend and I want to ride, any help is VERY much appreciated :D

Any update on spark test? This does sound like a fueling issue, even if there is fuel in the line the pump may not be priming. Can you hear the pump "whirring" when you turn the bike on before cranking?

Sorry, I put the resolution at the top of the post as an edit, probably should have just replied to it, my bad :)

It was a tip over sensor installed upside down. Took me way too long to figure it out.

I'm glad you got your bike running again!

I've been having trouble with the battery on my 2017 Z650 and dropped my bike tinkering with it in the driveway because I forgot to put the kickstand down... Oops! I did not restart my bike before removing the battery. I got a replacement battery and installed it. Now, my bike will not start. It turns over in Neutral but will not start. I am wondering if it is the tip over sensor, but I cannot locate it on my bike.

Would you be able to tell me where the tip sensor is located?

Thanks a bunch!

It's underneath the gas tank towards the front on the right hand-side. It will have the word "UP" on the rubber housing. It's about 1"x1" or so. Somewhere around the red circle below.

If you take a look and can't find it, let me know and I'll take a picure (avoiding that becuase tank has to come off, but no biggie).

Thanks! I found it, and now I'm not sure how to tell if it needs replaced or not. I was actually able to remove it without taking the tank off. I accessed it through the left side once I removed the left fairings and ignition cover, I was able to remove the sensor. When I tip the sensor it seems to be working smoothing from what I can hear/feel. I plugged it back in, but my bike is still behaving the same way. I guess I will run down to the Kawi dealership and see if they have a replacement before I move on to the next possible issue.

Let us know what you find out. It'd be good to get another non-start issue solved and documented here👍

The "New" battery I bought was bad or just not working as I needed it to. All I had to do was get another battery.

The first battery I purchased at a battery store. It was a 12V battery and stated it was for motorcycles and ATVs. After speaking with the local Kawi dealer, he suggested it might be the battery since I didn't get the "New" battery from a motorcycle specific shop. He said that the bike wouldn't start with a charge of less than 12.6. The battery I purchased was reading 12.9 fully charged, but as soon as I took it off the charger it would drop down to 12.3. I ran to a dealership and bought another new battery, and it started right up. Problem solved!

See this so much check the basics first. People seem to think the worst. Do you basic checks, then move on.
