(video) Unusual noise when running and turning off
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. |

The noise is the fuel pump. Seems kinda loud, but I don't hear anything to be concerned about.

Thanks csmith12 for the answer. I'm not referring to the noise when starting the bike though, but when the bike is actually already running. Might be hard to hear, but there is another noise going on besides the normal engine noise. Also, have you heard the noise when turning off the bike? That's definitely easily heard, and not normal. |

I hear what I think is a starter drive making noise. Obviously when hitting the button to start it, but it does make a similar noise when the engine shuts down.
Not sure if that's common or a problem. Could the starer drive possibly not be disengaging? |

I did hear the hiccup at the end of the vid, and it kinda goes along with other comments thus far. If I hear that and my starter is still strong, then I would suspect the starter clutch. Is that a common problem? I don't think so on 250's, but as you have a 300 it might be as they don't have years of history built yet.
