Thanks everyone, I did smooth them out but I didn't bevel them to the extent of the pictures. I'll pull it this weekend and see what happens. Once again thanks!!

Be sure to let us know if that fixes it. I'm battling a similar whistle out of my 62 mm bored TB. I very lightly touched up the sharp edges with my dremmel, but didn't take off anywhere near the amount from the write-up. I still have the whistle, so I'm looking for a solution...

That did indeed fix it. I didn't go deep enough the first time and it still whistled slightly. Took it back off and went deeper and the whistle is completely gone now!

Good man. I get a failing grade and you get rid of the whistle.

Just an FYI on this thread:

If you bore to 60mm there is no need for a new flutterby....... Works fine on mine.

Beveling the port eliminated my whistle too. Thanks for posting the writeup! I ended up beveling the top port above the butterfly a little bit too b/c I blew compressed air over it to clean off any metal flakes and got a slight whistle.
