Weird starting noise
Anybody know what is causing this? I got the bike running fine after a few carb cleanings, and it ran and idled like new. After putting on all the fairings, my '12 ninja does this...

I’ve had a sound just like that before, and it was indeed the battery. Needed a new one.
But yes like the above poster mentioned, I’d put a multimeter on it with everything off. Should be somewhere around 12.5-12.8 if I remember correctly.

it's actually drop in voltage when cranking that'll tell us if battery's any good. Let's see those numbers.

Resting voltage is 13.15 volts Cranking voltage went from 11.95-12 volts I will bring the battery in to my Advance Auto for a proper testing. Definitely wondering what is causing that metal slamming sound! EDIT: The mileage is 4400, and it seems the bike has spent some considerable time sitting in the weather, I bet with no cover/partly covered. |

Hmm, voltage drop isn't excessive. Do one more test to verify:
1. jumper with known-good auto-battery. Connect battery with car not running. 2. measure before and during cranking voltages This might not be as simple as it seems. Could be starter-clutch weld is cracking. Does it make difference in sound with clutch-lever squeezed? |

Just a few minutes ago I had it running and it idled well, so it seems the carbs are not an issue any further, but I need the oil change to give it a proper ride test. When it makes the metal noises, I disconnect the battery for about 5 minutes, and that makes the bike able to crank or start without the metal noise. I forgot to test the voltage when running and on a successful start. Will post those later, if they help. |
