Do the aftermarket fuel screws tend to give you the feeling that they could loosen, I know that there is more leverage. I am coming off a 2 stroke, and wonder if you need to mess with a 4 stroke more or less . I ride between 4,000 and 11,000 ft. on my yz 250 I would only have to adjust the air screw a quarter turn depending on temp , and of course a main jet up or down. After looking around the carb on my 06 wr I don't want to mess around any more than I have to. Also how far out do most of you have your fuel screws set at and with witch pilot jet thank you.
