I'm fixing to take my TB off and give it a good ole cleaning. However I had BNut ask me if I was going to port it also. I wasn't sure how to and neither was he, so I went searching on the net for instructions and found these 2 places:

I'm a little hesitant to do this but I really want to.

Has anyone out there done this to their TB before? If so can you give me some pointers or tips that would be helpfull. Thanks alot.

Don't do it.
You have to have the flap/valve thingy the right size to your new ported diameter or you'll start to run lean. You'll just end up retarding your timing, getting poor mixture and gaining no power.

Do not port unless you know what you are doing and have a flow bench. You will do more harm then good.
