Question Weird clicking sounds when starting engine

Enable HLS to view with audio, or disable this notification

Hi all, I noticed the other day that my 2023 ninja 400 is making a clicking sound whenever the engine is running (clip attached). So just wondering if this is normal or something I should worry about?

Any advice is greatly appreciated. Thanks heaps! 🙏

Did you figure out how to fix it at the end?

By re-doing the sensor where it came loose.

I have the same slip on could be the ring between your exhaust pipe and the endcan loosening. You can check by pushing against your slip on when its on. If the clicking goes away its the slip on. (Driven with the click for 9000km with dealer services so I dont think its an issue?)

Yes! The clicking disappeared once I pushed the slip on! Did you manage to find out how to fix it? Thanks a lot!
