Welcome to CRF's! You're on the right track. You'll want to do a number of things simultaneously. Open the airbox, re-jet with the JD jetting kit (available here on CRFs), for ease of maintenance I would recommend switching to the Twin Air Powerflow kit with flame resistant filter (air filter), napalm filter screw. While you're re-jetting it would be a great time to add the CRFs fuel screw (makes adjustment way easier). There is a wealth of info on this site, it has a great search feature and even greater people who are always willing to help.
