Need an experienced plug read

I wish there was some kind of rick single I could flash in the sky. Possibly some version of the yamaha star?.... . The #3 plug is not firing at at all anymore. Yesterday it ran "fine" for a few miles and then starting getting hesitation. That soon turned into a lack of power which soon turned into a... unplanned stop. On the side of the road i checked my plugs to find 1 and 2 badly fouled. #3 clean as a whistle and not appering to have fired and #4 looking lean but not bad. I was able to get the bike running enough to get it back. I then rode the bike hard until it starting show the same symptoms in an attempt to recreat the same problem. When the bike starting getting a hesitation I pulled it into the shop and this is what the plugs look like. I think i'm gonna have to pull the carbs again this week to check the jets on 3. Any other thoughts on the plugs? Any tests you can think of to narrow down the issue? Thanks guys. Note: I tried to put up pictures of my plugs but I am horrible with computers.

 

Tommy the error is obscure - you need to size your pics to 500x500 max.

 

I tried cropping it down but could only get it to 1500x1500 with microsoft paint. Is there an easier way?

Did someone shine a searchlight with the Yamaha Logo across the sky?
