[QUOTE="CaptainObvious, post: 711533, member: 17060"] Adjusting the air screw isn't going to cure a spooge problem. The airscrew really affects throttle response below 1/4 throttle. More than likely your pilot jet is too rich, a very common problem. If you are happy with the throttle response above 1/4 throttle you needn't worry about the needle, however, if the bike seems a little fat in the mid range you might want to raise the clip by one position. But before you go changing jets and needle positions, make sure that your air filter is clean and that you repack your silencer. Both of these items can lead to jetting that is too rich. [/QUOTE]
