Thanks shiney, there was oil on the plug, now whether or not that caused it to turn black I dont know.  I ran it past a buddy of mine locally who seems to think all the carb work I did on the bike could have fouled out that plug.  I put the new plugs in while working on the bike over the winter, then Ive had the carbs off and on 4 times.  He seems to think I should just replace the plug and not worry about it.  Im just wondering what could cause that and is there more going on that I should be concerned with then just carb work fouling out a plug.  Why would it only foul out that particular one?  Thanks for the response.
I know enough to get me in trouble.
