setting the carb bro is trial and error..
make sure to start to the richer mixture first and adjust to the smaller jettings accordingly or one at a time..
dont rush things..be patience to jet your carb..
and dont forget to sparkplug reading..too lean will eventualy damage your engine like piston,valves..
too rich mixture-running your engine too rich will result in your engine not running at its best bro..
right reading to the Sparkplug bro is brownish color..hope to help Bro..

I guess you are using Keihin PE 28 series carburetor similar to Honda NSR SP carburetor, so for 150 cc displacement with hi duration and lift cam you can try start Pilotjet from 42 and 115 for Mainjet.
Do this combination first and don't forget to check your spark plug color so you can decide to increase or decrease your jetting combination.
