Trying to pop start my bike
How’s is it going ninjas in a little bit of a dilemma I am trying to pop start my bike due to the fact that when I laid my bike down the housing for the starter crank or stater broke off inside my crank case. I clean the carburetor add a new oil cleaned out my crank case put everything back together but I’m getting no fire. My battery does seem to be a bit low so I’m going to charge it other than that I’m out of ideas as to why it won’t turn over Any suggestions I’m willing to do appreciate it

Battery also powers ECU and ignition-coils. If battery is weak, you won’t get any spark even if you can push-start it quickly enough. Don’t just charge battery, measure its voltage:
1. Key off, measure battery voltage 2. Measure battery voltage while cranking |

So after letting it charge For a little bit it was showing 11 1/2 and then I tried popping it a couple times as well checking my blinkers tested it again and it read 10 1/2 . Would be clutch relay or kickstand have anything to do with it not firing

No, battery is way too weak. Should be about 13.8v off charger and about 12v when cranking.

🤦🏻🤦🏻🤦🏻🤦🏻🤦🏻🤦🏻🤷🏻🤷🏻🤷🏻🤷🏻🤷🏻
This is so frustrating!!! I feel resistance while in first and clutch lever engaged . Which I never felt before while popping it ! It’s as if my clutch isn’t fully engaged. It used to feel like when my clutch was engaged in first like I was in neutral until I released it and then it would fire

Stop trying to pop start bike! You’ll cause more damage and end up destroying engine!!
Do it properly and fully charge battery and/or get new one. Now let’s backtrack and post photos: 1. What exactly broke? Show us the pieces. 2. How was this repaired? Did you get new case cover and starter? 3. Did you fish out ALL broken pieces from crankcase? Matched them up to broken case and starter to confirmed you got EVERY broken chunk out? Show us the pictures! I’m thinking there’s metal bits and pieces that wan’t recovered and they found their way into clutch. I would completely disassemble clutch and clean to verify it’s in good condition. There’s never enough time to do job right first time, but there’s always time to do it again! Often on side of road in complete darkness. |

Update
So this is the starter crank the housing that is attached to is what broke off which has made my electric start non-usable so I’ve had to resort To pop starting it. So I replace the battery replace the spark plugs drained the crank case made sure that I got all the metal shavings out refilled with new oil new coolant. I had to replace the handle bar and clutch lever with an aftermarket bracket. The clutch relay that attaches to bottom of the bracket won’t fit so I’ve left it off . Would that keep it from firing and if so how can I bypass it ? It’s still not firing. Could it be the kickstand or the clutch relay keeping it from firing up

Clutch switch only deals with starter circuit. You need to measure and come up with some numbers for fast and efficient troubleshooting:
1. Key ON, put transmission in neutral. Does neutral light on clocks come on? 2. Key OFF, what is battery voltage? 3. Key ON, what is voltage at each red-wire terminal of each ignition coil? 4. kickstand switch. How much resistance/ohms from each kickstand-switch wire to chassis ground? |

So battery reads 13 in key off position, when I turn key on all dash lights come on and are bright . It reads 12 while key is on. Like I said it’s a brand new battery

Also I wasn’t sure if I was clear the side that I laid my bike down was on the left side of the bike kickstand side and the kickstand did receive some minor damage

I’m getting 12. On the red terminal wire on each side.

Just because it's new doesn't mean it's good. Over 1/2 of stuff from auto-parts stores are bad right out of box and needs to be tested. ALL batteries needs to be charged before use. Did you charge it? Put battery on trickle-charger for 24-hrs and if it's not over 13v and stays over 13v when key ON, you'll need new battery. Here's how to use multimeter: https://learn.sparkfun.com/tutorials...multimeter/all Update on #4: unplug kickstand from harness. 4a. measure resistance between terminals of kickstand switch with stand UP 4b. measure resistance betweem terminals of kickstand switch with stand DOWN 5. pull every fuse and measure resistance between legs. Measure every fuse and list results here. |

I wasn’t getting anything out of the kickstand safety. I measured both the from the female to the wiring connected to the kickstand . I’m going to look to try and bypass the safety killswitch . And conduct the test of the fuses .

A 12 volt battery reads 12.7V when 100% charged. A reading of 12.0V is about 40% charged. Your most important reading is under load (cranking) which should stay about 10.0V minimum. Sounds like a bad battery to me as well. |

I would charge the battery regardless but that's probably no the culprit. I was able to push start my bike when I purchased it and the battery on that was totally shot after 12 years of usage. I think it was reading about 10v. If the neutral and oil pressure lights come up and are not dim that should allow the ignition to work. The electric starter would obviously not work. I saw that on many bikes of the 80ies that had a kick starter. Sometimes they would even start when the lights are half dim. Ninja is of a newer tech but my experience with the bat confirmed they are still capable to start on a garbage batt. I would not run it with a shot batt, however, as it will overheat the rectifier.

Trying to get it to run right with a questionable battery is going to complicate the troubleshooting process, but whatever... |

On old style points-style analogue ignition, you can probably get by with 10v battery charge.
But with new style digital ignition like on Ninjette, ECU won't work on anything less than 12v. I wonder if there's issue with 100-ohm resistor here... |
