Still got a gerbox noise

[buzzawak]

Hi guys, it’s been a little while since I was last on, been busy with my bike club.
I am still getting some gear box noise. Symptoms are a bearing noise which is noticeable at idle in neutral and
decreases with the clutch pull in. I have replaced the clutch basket needle roller bearing thinking that may be the culprit but this has not helped. The noise does not effect clutch operation or gear changes.

Wondering if anyone has a similar problem and knows the possible cause?
