Mine does the same, seems to get louder with more wear on the belt.

 

Had the same problem at a little over 900 miles, I took an air hose and blew out the clutch and replaced with a new belt. Sounds like it did when it was new.

 

I purchased mine at 1800 miles. It had a belt squeal when I let off the gas. I changed the belt at 3000 miles and there was no squeal. Now the squeal is back after a few hundred miles. I understand that a good cleaning of the sheaves with alcohol a scotch bright pad dose the trick. I haven't done that yet though.
