I had posted a thread about weird, knocking noise cumin' from the rear wheelor a drive chain that I could not specify. {it was a CBR 1000 F '94}
https://cbrforum.com/m_228605/tm.htmSudden noise - scared to ride it !
And what it was?
Rear sprocket carier fell apart. Literally into pieces. When I took it for a service the first mechanic did not even pull the wheelout otherwise he would notice there is something wrong. Interesting was that since that happend the terrible knocking noice didnt appear again and I was riding with it another 2000km. {Honda }Well..I replaced it + as well as chain and sprockets, wheel bearings and everything is nice and smooth again.
That sprocket carier that actually looks like a bearingwas $20 {AUD}and wears out by its age and all that dirt picked up on the road.
Hope that will help to detect somehidden noises for someone else.

Cheers.

 

Good one man!! That is nice to know for future reference
