nice exhaust....is that the patriot defender? I bought one from a member on here an I really like the sound!. My plugs look similar to yours...a little rich...but I'm only getting 34 mpg! might be riding style, I like to jump on it an it has a cam. I read somewhere that if the bike is running well but plugs look a little rich some fuel may be getting into the vac line on the stock petcock causing it to be a little rich.
