All plugs will look like yours if the bike is regularly started from cold and even run at idle to 3500. The 600 runs slightly rich and the plugs will never get hot enough to burn off the carbon caused what you are doing. Take the bike for a motorway run of 15 to 20 miles and then check the plugs on return when the engine cools down. This will give a much better idea of the how the carburation is doing.Uneven idle can be caused by out of balance carbs.
Not ideal but much better than starting it and letting it idle for a long period. The colour tune kit is not much use on the more modern bikes like the Fazer as the carburettors are of a better design to the ones back in the sixties/seventies when the colourtune was first marketed. I used to use the colourtune on the my old Ford Carpri 2.0 V4 and 1.6 GT but would never even consider using it on the fazer.I agree with His Dudness, set everything to factory setting, (unless you have a 90 Degree Bevel Screwdriver it will be carbs off the set the pilot screws) clean the plugs you have or wait until the new ones arrive, change/check the air filter, balance the carbs, set the TPS after balancing and setting the isle speed and go for a good 20 mile spin.If you still have problems come back to us.
