      I just looked at his previous posts and found that he has installed "cone filters", so he needs to re-jet for them.

        exactly. the cone filters give me more air and lean out the mixture. so now i need to go to larger jets to compensate for more airflow. but i'm still new to moto ownership and mechanics so i dont know where to go from here. thanx
