You are only being tested while your bike is at idle. The three carb settings that control mixture at idle are: Fuel screw, pilot jet, and pilot air jet. The rest of them you shouldn't have to worry about for the purposes of passing emissions.

You listed that your jetting is currently stock. Is the bike still stock, or have the free mods been done to it? Does it still have the ACV (octopus)? The free mods - especially removal of the ACV can have a significant effect on the jetting.

I'm not sure what the ACV is. How can I tell if I still have it or not? When you refer to octopus all I think of are all the tubes hanging from the carb.....

The ACV is the octopus. See this thread for a description of the change and a picture of the bike with the ACV removed.
