I'd be looking at the needle bearing, and the bushing and thrust washer behind the clutch basket.
This bearing only come into play when the engine is running and the clutch is disengaged. When the bike is moving normally in gear, and the clutch lever is released, there is no movement of this bearing, and no noise from it.
