... when I am coasting and the clutch is pulled in. It only does it when rolling.
If all answers are no... NPF (no problem found):
0. Does the noise sound occur when idling clutch in, dead stop?
1. Does the noise sound occur when idling, clutch out?
2. Do I have a hard time finding N?
3. When riding, is there vibration on the clutch side?
4. Does my clutch lever loosen up when warm?
5. When I leave from a stop in 1st gear, is there any chatter when the clutch is engaging?
6. Under robust acceleration thru the gears, does the clutch slip?
Sounds more like you are hearing loose plates act like corduroy pants sipping back and forth, but more constant in the one direction.
