Hi people
My new to me 2015 CR.
55k miles
Full service history.
It is making a clunking noise under load from the sprocket/gearbox.
I have uploaded a clip. Listen for the irregular metallic click behind the engine and chain noise.
The chain was slack. I had it tensioned by the local bike mechanic. Now the sound is more prominent. It is louder when underway.
My description in the video reads as follows:
I'm hoping someone can tell me what's going on here please. There is a noise coming from the middle of the bike.
The chain was slack, so I thought the noise was from that. The noise was obvious at low speed but went away.
With correct tension on the chain, the noise is worse and present at all engine speeds. The chain is definitely not too tight.
The video clip shows the bike running in first gear on centre stand. Behind all the chain noise, there is a random click, coming from the front sprocket/ spindle gearbox area.
I'm thinking spindle bearing is worn after 55k miles. Or is there a broken tooth rattling around the gearbox (under load the noise is regular, I call it a rotational knocking. It speeds up with engine speed, so I suspect it's not a loose tooth).
Does anyone have any experience of this on their bike? What's the solution please?
