Hello Guys,

I'm having a rattle/knocking sound on the right side (clutch side) of the engine.
The sounds happens when is at idle and barely dissapears once the engine pass the 3k rpm's, but I can notice if I'm close to the engine.

Here's a video :

Ideas ? Thoughts ?

I disassembled the clutch cover and found everything in place, except that there's some play (backlash) between clutch basket gear and primary gear on the crankshaft. Here's a video showing it :

Do you think that's normal or I should replace the entire clutch ?

To isolate if there was a engine problem, I removed the clutch completely and started the engine for 10 seconds, the knock sound was gone.

So I'm stuck if the problem comes from :

- Clutch basket
- Tranny (I rotated it manually and didn't find any abnormal sound)

Thanks a lot guys !

What happens to the noise when the clutch lever is pulled or even just lightly grabbed (thus preloading the clutch springs)?
Almost the same thing. In the first video, I pull the clutch, the knock/rattle barely changes but is still there...

Could be the roller bearing in the clutch when it's not under load? Worth stripping the clutch down and making sure the bearings have no crap in them and that the centre nut is properly torque'd up and the nut is staked.
