after you figure out how to start it and all. you will want to check your plug when riding it real hard. for example that cam is good to 6500+
run the bike right up to 6500+ and then kill the motor and try to set your self up to coast back where you can pull the plug out. at this point you will be able to see the correct color. otherwise everytime you pull the plug out after you sat and idled, it will be BLACK. goodluck...
