All honda's come from the factory rich, they run rich so it can prolong the life of the engine. Itz nothing to worry about at all, just remember running rich is better than running lean. If you really want to get rid of this problem, purchase a piggy back and adjust the A/F Ratio to lean it out a bit (via Dyno of course). It will increase your performance slightly and improve your fuel consumption too. All another way is to reset your ECU, see if that helps as well, as it will refer back to the stock maps.
