Engine Knock; Doesn't Go Away When Clutch Pulled In

Do you have any wear on the inside of the clutch cover?

I have a knock coming from my engine and when I first took it apart I noticed wear on the clutch cover, but I put it down to old damage that a previous owner had repaired as there wasnt enough metal in the case to be recent. But since I have taken it apart again I decided to open the clutch pack and there was a huge amount of alloy fillings trapped in the top pressure plate. So I think that Crazybond is right about play in the main clutch bearing.

No wear on inside cover, but even the fill plug had a few small shavings. 

 

I believe the shop took apart the clutch discs and looked for shavings/fillings.  I only removed the entire basket as I didn't have a 12 point 7mm socket. 

 

I did check the main clutch bearing and it felt okay.  No real slop just little play when I rotated it clockwise/counter clockwise which I think is normal.

Inspect your gears as the tinyest bit of damage to them can cause huge knocking!!

 

This was my bike with a little dent in the clutch basket gear.
