Primary Noise When Down Shifting

When down shifting and letting out the clutch I hear a screech noise in the primary. It seems to go away as the bike warms up. I have changed the fluid and adjusted the tension with no luck.

I have seen and heard many rear drive belts act this way. Take a little WD40 and moisten the outside edge of the belt when cold. Do not use too much as it will collect road debris, try this and let us know. Also what model what year what mileage would be helpful.  Wrench Safe, FMH
