(video) Unusual noise when running and turning off

[prcsc]

Hi there guys,

I have been following this forum for a long time now, but never had the need to really post anything. I have found the forum extremely useful, so thank you all.

A couple weeks back, my ninja started making a weird noise when running. This noise has increased over time. I though it could possibly be low oil pressure, so I decided to change the oil, and oil filter at the same time.

Yesterday I ran the bike and the noise is still there.I have uploaded a video in Google drive - https://photos.app.goo.gl/mJ1b4zCOw1Djcg0z1

If you pay attention, the noise start when I turn the bike on. It's kind of a mixture of soft grinding and low whistle. Please watch until the end because it also makes an unusual noise when turning the bike off. Both noises started at the same time, so pretty sure they are related.

Does anyone have any idea what this could possibly be?

Thanks in advance.

Sounds like the starter motor pinion to me but wait for more experience peeps on here.

The stopping noise sounds like a starter motor so I wonder if the starter motor fails to disengage properly and is being spun by the engine. Faulty solenoid? Not sure though.

What could I try then?

Definitely starter motor. To me it sounds like its still trying to turn over the engine when you stop the engine until you switch it off.

If you have the kill switch on, can you still turn the engine over on the starter motor? If you can, start the bike then stop it on the kill switch and see if the starter is still turning it over.

Don't run your bike like that it will wreck the starter very quickly and the starter gear too, possibly causing broken engine cases.

At first I thought it was the starter clutch not disengaging but it actually sounds like the starter is still under power whilst the engine is running.

Suspect the solenoid first, since it's that which supplies power to the starter.

The others have pretty much covered it. I just wanted to say well done on a first post that gave us everything we needed, a good description of the problem and a video. Noobs could learn well from you
