Do you have to re-jet? I removed the airbox lid, and put on a K&N Filter with outerwears.

As the temperature fluctuates you will have to rejet to compensate for the change in the air to fuel ratio (temperature change alters the density of the air). When it is cold you will have to jet richer. Because of this I would suggest buying a kit or several sizes...it will save on shipping later. you will obviously have to go bigger than what you have now, try 4 or 5 jets of the next bigger size.
