either move needle clip or drop down in jet size.
once you find a jet that you think is the one then do the test. ride with 1/4 thrtl see what motor does. does it run away or load up.
then do half thrtl then full thrtl. if bike want to rev up then its lean, if it holds and runs smooth then your good. if it starts to load up then your rich.
i would try a 185 to 180, to start
